Mobile networks in the United States
A travel eSIM has no network of its own: it uses local operators. The plans for the United States list these:
| Network | Best technology | Plans for the United States only | Regional plans |
|---|---|---|---|
| Verizon | 5G | 28 | 5 |
| AT&T | 5G | 28 | 1 |
| T-Mobile | 5G | 0 | 1 |
5G is listed on all of them. When a plan lists several networks, your phone picks one automatically and you can choose another in the network settings. 5G needs a 5G phone and 5G coverage where you are; elsewhere the eSIM uses 4G/LTE.

How to set up an eSIM for the United States
-
Check your phone
It must support eSIM and be unlocked, not tied to one carrier. Most phones from 2019 on support eSIM, but not every regional version does: look for Add eSIM in your settings.
-
Install it before you leave
Install the eSIM over Wi-Fi from its install link or QR code. It stays idle until you switch to it.
-
Switch on when you land
Turn on the eSIM line, choose it for mobile data and turn on data roaming for it. Keep data roaming off on your home SIM to avoid your own carrier's charges.
-
Give it a few minutes
The first connection can take a few minutes. The eSIM connects to Verizon, AT&T, and T-Mobile.
