Best eSIM for global travel in 2026

A global eSIM is one data plan that keeps working as you cross borders, so you do not need a new SIM card at every airport. It is installed on your phone before you fly and sits next to your home SIM.

Twelve providers sell this kind of plan, and they differ in coverage, price, payment options and what happens when something goes wrong. We compared them on the same six criteria, using each provider's own pages and terms checked in October 2026. The key takeaways come first, then the full comparison.

The best global eSIM in our ranking

TonMobile is the best eSIM for global travel in our ranking in 2026. It lists more than 180 countries and sells local, regional and global plans, including unlimited options. It also takes crypto alongside cards and wallets: Visa, Mastercard, Apple Pay, Google Pay, Bitcoin, TON and Telegram wallet.

TonMobile is also one of the easiest to buy from. You can use a Telegram bot, a web app, or the iOS and Android apps, and the home page says no documents are required. Refund requests can be reviewed up to 180 days after purchase, under the conditions in its terms.

The short answer

The best international eSIM depends on how you pay, how much data you use and whether you need a number. Each of the twelve providers below is the strongest fit for one kind of trip. Pick the card that sounds like you, then read the full review further down.

The scores behind this order come from six criteria: coverage, plan range, payment options, buying and setup, refunds and support, and extras. Our methodology page explains how each criterion is scored. The full table sits on the eSIM provider rating.

Why TonMobile ranks first

TonMobile leads the ranking on three of the six criteria: plan range, payment options, and buying and setup. Ubigi lists wider coverage, and Airalo and Saily score higher on extras. TonMobile's lead comes from being strong across all six rather than best at one.

• Plan range: local, regional and global plans, with flexible and unlimited options
• Payment: Visa, Mastercard, Apple Pay, Google Pay, Bitcoin, TON and Telegram wallet
• Buying: a Telegram bot, a web app and iOS and Android apps, with no documents required
• Refunds: written rules, a 180-day request window and set payout times

Global eSIMs compared

A global eSIM is one data plan that works across many countries without a SIM swap at each border. The table below sets the twelve providers side by side, using what each one lists on its own pages in October 2026. Coverage counts are provider claims, not our measurements.

Coverage numbers are not directly comparable. Some providers count countries, some count destinations, and Airalo counts "countries and networks". A destination list can include territories that a country list folds into one entry.

Two patterns stand out in the table. Fixed-data plans from Saily and Nomad suit trips where you know roughly how much you will use. Unlimited plans from Holafly and Airalo cost more over 30 days but remove the need to watch a counter.

The twelve providers, one by one

The reviews below follow the order of our ranking, from first to twelfth. Each one lists what the provider sells, what it costs where prices are published, and where it falls short. Facts come from the providers' own pages and terms, checked on October 27, 2026.

1. TonMobile

TonMobile is a travel eSIM service that sells data plans for more than 180 countries. Its home page describes it as "affordable internet for travel in 180+ countries". The App Store and Google Play listings go further and describe plans for about 200 countries, regions and global coverage on 4G and 5G networks.

TonMobile sells three plan types: local, regional and global packages. The Google Play listing also mentions flexible and unlimited data options. Plan choices shown on the home page include the UAE, Turkey, China and a Global plan, alongside other countries.

A TonMobile global plan suits a multi-country itinerary where you would otherwise buy a new eSIM at each border. A local or regional plan suits a single-country stop or a trip inside one region. All three sit in the same account, so you can mix them on one longer trip.

Payment is where TonMobile stands out. The checkout shows these options:

• Bank cards: Visa and Mastercard
• Wallets: Apple Pay and Google Pay
• Crypto: Bitcoin, TON and Telegram wallet

The store listings sum it up as "pay securely with bank cards or crypto". Crypto refunds can be paid in USDT on the TRC-20, TON or ERC-20 networks, or in Bitcoin, according to the terms. Our guide to paying for an eSIM with crypto covers how that works in practice.

TonMobile sells through four channels, and its terms state that no channel is primary. You can buy in the Telegram bot @tonmobile (also reachable as @mobile), in the web app at web.tonmobile.com, or in the iOS and Android apps. The Telegram bot page showed 29,857 monthly users on October 27, 2026.

Buying takes three steps, as the home page puts it: open TonMobile, choose a country and plan, then install in a couple of clicks. The store listing adds that you can install in a few taps and turn on data when you land. The home page also says "no documents required", so there is no ID upload at checkout.

The app's release notes list several features that matter on a long trip:

• Top up the same eSIM without reinstalling it (mentioned in a user review)
• Track remaining data and validity in the app
• Gift an eSIM or buy several eSIMs at once
• Send the QR code to another device
• Sign in with Telegram
• Earn cashback into a bonus balance

The bonus balance collects cashback, referral rewards and promotions in US dollars. Under clause 17 of the terms it expires after one year and cannot be withdrawn. Treat it as a discount on future plans, not as cash.

Store ratings are positive but still thin on iOS, where only 5 ratings had been left by October 27, 2026. The iOS app is available in English and Russian.

The refund rules are written out in clauses 12.4 to 12.8 of the TonMobile terms. A request can be approved before the package expires and no later than 180 days after purchase, for set reasons such as an unsupported device or data that cannot be enabled. The full conditions and timings are in the fine print section below.

Support runs from 06:00 to 23:00 UTC+2, through the platform or support@tonmobile.com. The service is operated by Intermob Limited, a Hong Kong company (number 79904463) trading as TonMobile. Its services are not available to Hong Kong residents.

TonMobile's plans carry no phone number and no SMS, which its terms list as a functional limitation. The store listings note that your home SIM and number stay active, so SMS from your bank still arrive on the home line. If you are new to the format, the TonMobile eSIM explainer covers the basics before you open the plan list.

2. Airalo

Airalo is a travel eSIM store whose Global eSIM page lists packages starting at $8.50. Its Discover page lists coverage across 168 countries and networks. Airalo's pages do not all quote the same country count, so check the list for your exact route.

Airalo lists unlimited global packages at three lengths. Three days cost $24, seven days $45 and thirty days $159. Top-up and auto-renewal kick in when 10% of the data remains, so a plan can refill itself before it runs dry.

Calls and texts are the main reason to choose Airalo. Its meta description says packages come with data, calls and texts. Independent reviews, such as Saily's review of Airalo, describe Discover+ as adding a phone number with calls and SMS.

Airalo is the stronger pick than TonMobile when you need a foreign number for a booking or a ride app. TonMobile is the stronger pick when you want to pay in crypto or buy through Telegram. On price, the 30-day unlimited global package is the cost to watch on longer trips.

Airalo's unlimited global pricing gets cheaper per day as the package gets longer, as the table shows. Holafly's listed 30-day price works out to about $5.38 a day, so the two sit close at that length.

See the current list on Airalo's Global eSIM page.

3. Saily

Saily is a travel eSIM built by the team behind NordVPN, and that shows in its extras. The Global plan adds a virtual location, an ad blocker and web protection to the data line. Its global coverage is listed at 121 destinations.

Saily's long validity is its standout plan feature. A 20 GB package lasts 365 days, which suits travelers who take several short trips a year. You keep one data balance instead of buying a new plan each time.

Saily also offers an optional US phone number. The number requires identity verification, so it is not an instant add-on. Saily covers fewer destinations than TonMobile or Ubigi, which matters if your route includes less common countries.

Saily's price per GB falls sharply as packages grow. The 1 GB package costs $8.99 per GB, the 10 GB package about $5.70, the 20 GB package about $3.35 and the 50 GB package about $2.60. Price per GB here is the plan price divided by its data allowance.

Saily suits a frequent traveler who wants one balance for the year and values the NordVPN team's security tools. It suits a heavy user less well, since every package has a fixed data cap.

Check the destination list on Saily's global eSIM page before you buy.

4. Holafly

Holafly sells an eSIM with unlimited data for global travel, priced by trip length. Its Global eSIM lists 142 countries. In December 2025 Holafly also launched a month-to-month unlimited global plan covering more than 160 countries.

Holafly's unlimited plans come with two limits. Hotspot sharing is capped at 1 GB per day, and a fair usage policy may slow your speed for up to one day. Neither limit matters for maps and messaging, but both matter for laptop work.

Holafly's price per day falls with longer plans. The 3-day plan works out to about $8.30 a day, the 15-day plan to about $6.46, and the 30-day plan to about $5.38. For trips beyond a month, the month-to-month unlimited plan launched in December 2025 is the line to compare.

Holafly plans have no phone number. Holafly beats TonMobile for travelers who never want to check a data counter. TonMobile is the stronger pick on payment choice and channels, with crypto checkout and a Telegram bot.

Prices and the country list are on Holafly's Global eSIM page.

5. Yesim

Yesim sells global eSIMs under several plan names. Global Plus lists 146 countries, Pay & Fly lists 170+ countries from €0.92 per GB, and the Unlim Day Pass covers 83 countries from €2.48 a day. Prices on its pages are in euros.

The Global Plus page lists fixed packages from 5 GB for 30 days at €24 to 40 GB for 365 days at €109, and unlimited plans at €65 for 7 days and €99 for 15 days. Unlimited plans are subject to the operator's fair usage policy. An eSIM must be activated within 180 days of purchase, validity begins when it connects to a network, and the QR code works on one phone only.

Yesim's refund rule is one of the clearest in this ranking: refunds are available within 30 days of purchase for unused data plans and top-ups, while used or expired plans are not refundable. The footer lists Visa, Mastercard, Apple Pay, Google Pay, PayPal, UnionPay, JCB, Discover, Diners Club and American Express, but not crypto. The plans are data only, and virtual numbers are sold as a separate product.

See the current plans on Yesim's Global Plus page.

6. Nomad

Nomad is a travel eSIM brand launched in 2020 by LotusFlare. It runs two global lines with different coverage and pricing. Nomad lists 200+ destinations across its full range of plans.

Nomad Global-EX lists a low price per GB, from $2.58. The catch is coverage: Global-EX lists 98 destinations against 123 for Nomad Global. A route that leaves the Global-EX list needs the pricier Global line or a second plan.

Price per GB is the plan price divided by its data allowance. Nomad publishes that figure directly, which makes comparison easier. Our eSIM glossary defines price per GB, validity and other terms used on this page.

Nomad Global-EX and Saily's largest package land close on price per GB. Global-EX lists from $2.58 per GB, and Saily's 50 GB package works out to about $2.60. Nomad Global-EX covers 98 destinations against Saily's 121, so the route decides between them.

Nomad suits a long stay that stays inside the Global-EX list, such as a multi-month trip through a set of covered countries. It suits less well a route with a few rare stops, where the Global line or another provider fills the gap.

Both lines are listed on Nomad's shop page.

7. Ubigi

Ubigi is a data-only eSIM brand that belongs to Transatel, part of the NTT group. Its World plans list more than 200 destinations, one of the widest coverage claims in this ranking, alongside Roamless, Jetpac and MobiMatter. The World 20 GB plan is a monthly subscription at $44.

Ubigi's World 20 GB plan renews automatically each month. You can cancel only after three months, so it suits people who travel most of the year. Data sharing is allowed, and you can recharge in the app without Wi-Fi.

Ubigi uses Smartstart, which activates the plan on arrival. The plan has residency limits: Canadian residents cannot use it in Canada, and UAE residents cannot use it in the UAE. Ubigi beats TonMobile on listed coverage, while TonMobile is more flexible for a single trip with no subscription.

Ubigi's World 20 GB plan works out to $2.20 per GB each month. The three-month minimum means the smallest commitment is three payments of $44, or $132 in total. That is good value for a year of travel, and poor value for a single two-week trip.

Plan terms are on Ubigi's World 20 GB page.

8. Roamless

Roamless describes its coverage as 200+ destinations, meaning countries and regions. Its help center lists three plan types. Pay-as-you-go credits are billed per MB, start from $1.95 per GB and never expire. Data plans of 10 GB or 20 GB are valid for 30 days, from $0.58 per GB. Unlimited plans give 3 GB a day at full speed, then reduced speed until the next day, and validity starts with your first KB of use.

The eSIM is data only and has no default phone number. You can subscribe to a Roamless Number, monthly or annually, to receive calls and SMS. Its overview does not list payment methods or refund terms, which is why Roamless scores lower on those two criteria. Rates differ by country, so check the live price for your route.

See the current plans on Roamless's site.

9. Jetpac

Jetpac's home page lists 200+ countries but not the countries themselves. Its FAQ says packs are valid for 3 months after purchase, and gives an Explorer example of 20 GB with 30-day validity. Voice packs start from USD 1.99, while traditional SMS is not supported.

Jetpac says there is no fair usage policy: the data you buy is the data you get, so plans are capped by pack size. It advertises a 100% money-back guarantee and a flexible refund policy; the conditions sit in a linked PDF, so read them before you buy. Payment methods are described only as easy and secure, and data prices are chosen on each destination page.

See the current plans on Jetpac's site.

10. Breeze

Breeze lists eSIMs for over 190 countries, with country plans such as the US, Canada, Japan, Spain and Turkey, and regional plans such as Europe Lite at $12.99. Most listed plans are 10 GB for 30 days, with Turkey at 20 GB. Its headline says data plans from $3.99.

Payment is the strong point: Breeze lists Visa, Mastercard, American Express, Apple Pay, Google Pay, PayPal, UnionPay, JCB, Discover, Diners Club and more. The eSIM is data only and can sit next to your existing SIM. Breeze does not show a single global plan on its home page, so it fits a trip inside one country or region better than a route across continents. Unlimited plans are mentioned without prices, and refund terms link to a complaints policy.

See the current plans on Breeze's site.

11. MobiMatter

MobiMatter is a marketplace whose headline is eSIM packages for 200+ countries. Offers on its home page include Turkey 12 GB for 30 days at $8.99, Thailand 50 GB for 10 days at $9.99 and Asialink 20 GB for 30 days at $19.99. The featured Global plan is 13 GB valid for 365 days at $41.99.

MobiMatter runs a rewards scheme: members get 10% cashback with every order, and referrals earn up to $5 in credit. The home page links to a delivery and refunds policy but does not state the terms, and it does not list payment methods, phone numbers or unlimited plans. The Global plan lists fewer countries than the marketplace headline, so check its country list against your route.

See the current plans on MobiMatter's marketplace.

12. Maya Mobile

Maya Mobile's global eSIM is unlimited only. The page lists 165+ countries with the same unlimited data in each, and four lengths: 3 days at $9.99, 7 days at $19.99, 14 days at $27.99 and 30 days at $49.99. That works out to about $3.33 a day on the shortest plan and $1.67 a day on the longest.

The trade-off is range. There are no fixed-data packs and nothing longer than 30 days, and the global page does not list payment methods or refund terms. Maya suits a short multi-country trip where you want one flat price and no data counting; for a longer trip, compare it against the fixed-data plans in this ranking.

See the current plans on Maya Mobile's global page.

What a global eSIM is

A global eSIM is a travel data plan that works in many countries under one profile, installed on the eSIM chip inside your phone. An eSIM itself is a SIM profile downloaded onto a built-in chip called an eUICC, so no plastic card goes into the tray. A global plan simply puts dozens or hundreds of countries on that one profile.

Who actually carries your data

Travel eSIM sellers are resellers, not network operators. TonMobile's terms, clauses 2.2 and 2.3, state that the data is carried by partner networks in each country. The same model applies across this ranking: the brand sells the plan, and a local network moves the traffic.

The reseller model explains why coverage lists vary so much. Each provider signs its own agreements with partner networks, country by country. Two worldwide eSIM plans with the same headline count can still differ on which network you get in a given city.

1. You buy a plan

   The provider issues an eSIM profile for the countries on your plan, delivered as a QR code or an in-app install.

2. Your phone stores the profile

   The profile sits on the eUICC chip next to your home SIM. TonMobile notes that you can install it in advance, even while you wait for a flight.

3. A partner network connects you

   When you land, the eSIM attaches to a partner network in that country. Cross a border, and it attaches to the partner network there.

What a global data plan contains

Every global data plan is defined by a handful of terms. Read them on the plan page before you pay, since they decide whether the plan fits your route.

• Coverage list: the countries or destinations where the plan works
• Data allowance: a fixed amount in GB, or unlimited with a fair usage policy
• Validity: how many days the plan lasts, from a few days to 365
• Activation rule: on install, on first use or on arrival
• Hotspot rule: whether you can share data, and how much
• Phone number: most global plans are data only

Keeping your home number

A global eSIM does not replace your home SIM. Both lines can stay in the phone, and you choose which one handles mobile data. The TonMobile store listings point out that the home SIM and number stay active, so SMS from banks still arrive.

A data-only plan still lets you call and message over the internet through apps. What it cannot do is receive an SMS sent to a foreign number, because it has none. Our guide to travel eSIMs, phone numbers and SMS covers the options when you need one.

Global, regional, local or roaming

A global eSIM is the most flexible way to get data abroad, but rarely the cheapest per gigabyte. Regional and local plans cost less when you stay in one area. Carrier roaming passes are simple to switch on, yet expensive over a long trip.

The 2026 BytesIM price comparison shows the gap for a typical 10 GB plan lasting 30 days:

Prices for eSIM plans are from the BytesIM comparison published April 21, 2026. Day pass prices are AT&T International Day Pass and Verizon TravelPass, as reported by US Mobile.

When roaming adds up

AT&T International Day Pass and Verizon TravelPass are listed at $10 per day. A two-week trip comes to $140 on either pass. The BytesIM figures put a 10 GB global plan at about $35-60 for a full month.

TonMobile's home page claims its plans are "up to 5x cheaper than roaming". That is the company's own claim, and the real gap depends on your carrier and plan. Comparing your carrier's daily rate with a live plan price is the quickest check.

Mixing plan types

You do not have to choose one type for the whole trip. A long stay in one country plus short hops elsewhere can work well as a local plan plus a global one. Providers that sell all three types, such as TonMobile, keep them in one account.

Our guide to data for a multi-country trip walks through these combinations. For trips that circle the globe, see the round-the-world eSIM guide.

Who should skip a global plan

A global eSIM is not always the right tool. Three kinds of trip often do better with something else:

• A trip that stays inside Europe or inside Asia, where a regional plan costs less per the BytesIM ranges
• A long stay in one country, where a local plan fits the route exactly
• A one- or two-day hop, where a carrier day pass at $10 may be simpler

A worldwide eSIM earns its higher price when the route crosses regions. Two continents in one trip is the usual point where one global plan beats several regional ones on effort.

How to choose a global eSIM

The best global eSIM for your trip is the one whose coverage list matches your route and whose data rules match your habits. Price comes after those two. These seven criteria cover what matters, in roughly the order to check them.

1. Match the coverage list to your route

   Check every country on your itinerary against the provider's list, including layover countries. A headline count of 200+ means little if one stop is missing.

2. Choose fixed data or unlimited

   Fixed plans suit predictable use. An eSIM with unlimited data suits heavy use, but read the fair usage and speed rules first.

3. Check validity against trip length

   Validity ranges from 3 days to 365 days in this ranking. Saily and Nomad Global-EX sell year-long packages; Ubigi sells a monthly subscription.

4. Decide if you need a phone number

   Most global plans are data only. Airalo and Saily list number options; TonMobile, Holafly and Ubigi do not.

5. Confirm how you can pay

   Card payment is standard. TonMobile also lists Apple Pay, Google Pay and crypto, including Bitcoin, TON and Telegram wallet.

6. Read the hotspot and residency rules

   Holafly caps hotspot sharing at 1 GB per day. Ubigi bars residents of Canada and the UAE from using it at home.

7. Read the refund terms

   Look for a time limit, the accepted reasons and the documents needed. TonMobile accepts requests up to 180 days after purchase under set conditions.

Compare by price per GB, not headline price

Price per GB is the total plan price divided by the data allowance, as BytesIM defines it. A cheap small package can cost more per gigabyte than a larger one. The figures below are worked out from each provider's own listed prices.

Price per GB only works for fixed-data plans. Unlimited plans from Holafly and Airalo are better compared by price per day. TonMobile shows its prices live in the app, so compare there on the day you buy.

Price per GB check

Enter any plan you are looking at to see its price per GB and per day. The check compares the result with the 2026 BytesIM range for global 10 GB plans, about $3.50 to $6 per GB. It is arithmetic on the numbers you enter, not a quote.

How much data you might need

Data use depends far more on habits than on destination. Maps and messaging use little; video and hotspot use a lot. Treat any figure as a starting point and top up if needed.

Setting up a global eSIM

Setting up a travel eSIM takes a few minutes and works best at home, on Wi-Fi, before you fly. The eSIM can be installed in advance, and your home SIM can stay in the phone. These six steps cover iPhone and Android.

1. Check that your phone supports eSIM

   Your phone needs an eSIM chip and must not be locked to your home carrier. TonMobile's iOS app also needs iOS 15.1 or later.

2. Buy the plan

   Choose your country, region or global plan in the provider's app or web app. TonMobile sells through a Telegram bot, a web app and both mobile apps.

3. Install the eSIM

   Install from the app or scan the QR code. On iPhone, the eSIM option sits under SettingsCellular; on many Android phones, under SettingsSIM manager.

4. Label the lines

   Name the new line "Travel" and keep your home line as "Primary". Clear labels make the next step easier.

5. Set the travel line for data

   Choose the travel eSIM as the mobile data line. Leave the home line on for calls and SMS if you want bank messages.

6. Turn data on when you land

   Follow the provider's instructions on activation and data roaming for the travel line. TonMobile's store listing says to turn on data when you land.

iPhone and Android menu paths

Menu names vary by phone model and software version. On iPhone, eSIM lines live under SettingsCellular, where you can add a plan, rename lines and pick the data line. On Android, look under SettingsSIM manager or the closest match on your model.

A global eSIM shows as a second line next to your home SIM. You can switch data between them at any time. The glossary explains terms such as eUICC, ICCID and data roaming.

The first 30 minutes after landing

The first half hour after landing is when a travel eSIM either connects or shows a setup problem. A short routine on arrival saves time later. The timeline below is a simple order to follow.

• Turn off airplane mode and wait for the travel line to find a network
• Confirm the travel eSIM is set as the mobile data line
• Switch on data or data roaming for the travel line if the provider asks you to
• Open a map or a chat app to check that data loads
• Check that your home line still receives SMS, for bank codes
• Open the provider's app to see remaining data and validity

Some plans start counting days on arrival rather than at purchase. Ubigi's Smartstart is one example, activating the World plan when you land. Check your own plan's activation rule so the validity does not start early.

Before you fly

Most of the work for a smooth arrival happens before departure. A short checklist at home covers the steps that are hard to do on arrival.

• Install the eSIM and label the line
• Note where the provider's app shows remaining data
• Save the support contact, such as support@tonmobile.com, and the support hours
• Screenshot the eSIM settings page in case you need it for support

Refunds, unlimited plans and other fine print

The fine print decides how a global eSIM behaves when something goes wrong or when you use a lot of data. Four areas matter most: fair usage, hotspot caps, residency limits and refunds. Each provider handles them differently.

Fair usage on unlimited plans

An eSIM with unlimited data almost always has a speed rule. TonMobile's terms, clause 12.6, say unlimited plans reduce speed after a set consumption threshold. Holafly's fair usage policy may slow speed for up to one day.

A speed rule does not cut you off, but it can make video calls and large uploads hard. Light tasks such as maps and messaging usually still work at a reduced speed. If you rely on video every day, read the provider's fair usage terms before choosing an unlimited plan over a large fixed one.

Hotspot and residency limits

Residency rules are easy to miss because they sit in the plan terms, not on the price card. If you live in a country on your route, check that the plan allows use there. Ubigi and TonMobile both state such limits in writing.

TonMobile refund rules

TonMobile can approve a refund if you ask before the package expires and no later than 180 days after purchase. The terms, clauses 12.4 and 12.6, list four accepted reasons:

• Your device does not support eSIM
• The network is unavailable in the declared coverage because of the provider
• The eSIM was not delivered and not fixed within 4 hours of contacting support
• Data cannot be enabled for over 4 hours after contacting support

Instead of a refund, TonMobile may offer re-activation, a free new eSIM or an alternative local operator, under clause 12.5. A request needs the eSIM's ICCID, your device model and screenshots of the eSIM settings, under clause 12.7.

Crypto refunds can go out in USDT on TRC-20, TON or ERC-20, or in Bitcoin, or to a USD cash balance, under clause 12.8. The bonus balance from cashback is separate and cannot be withdrawn.

When the data does not connect

Most connection problems with a travel eSIM come from phone settings, not the network. The table lists common problems, a likely cause and a first fix to try. For a fuller walkthrough, see what to do when an eSIM is not working abroad.

If none of these fixes work, contact support while you still have some connection, such as hotel Wi-Fi. TonMobile asks for the ICCID, device model and screenshots of eSIM settings for any refund review. Collecting them early saves a second round of messages.
