Mobile network generations. Which one you get depends on the partner network and your phone.
4G LTE is the baseline speed for most travel eSIMs. 5G is available where the partner network has built it and where the plan and the phone allow it.
A plan page that says 4G and 5G describes what the provider can offer, not what every tower delivers.
What to check
- Your phone must support the local 5G bands
- Speed in a country depends on its partner networks
