T-Mobile US is one of the networks your eSIM may use in United States. Here is who actually decides which network you get, and what to do with that.
Quick answer
Wikipedia's list of 5G NR networks credits T-Mobile US with the first 5G NR standalone deployment, in August 2020.
| Item | T-Mobile |
|---|---|
| LTE (4G) | B2, B4, B12, B66, B71 |
| 5G NR | n25, n41, n66, n71, n77, n261, n262 |
| 5G launched | 2019 |
| 3G | Shut down |
| Network code (MCC-MNC) | 310-260 |
Checked against the sources on 2026-10-12. Only the bands a source confirmed are listed; the network may run others too.
An eSIM can only use T-Mobile if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.
Mobile networks in United States are licensed, and their spectrum assigned, by the Federal Communications Commission (FCC). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.
From the supplier record behind each package, 9 of the 67 plans we currently sell for United States declare T-Mobile US as a network the profile can reach, at 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.
| Network | LTE bands | 5G bands |
|---|---|---|
| T-Mobile US | B2, B4, B12, B66, B71 | n25, n41, n66, n71, n77, n261, n262 |
| AT&T | Not verified | n2, n5, n66, n77, n260, n261 |
A band shared across networks is one a single phone can use on all of them.
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If T-Mobile US is weak where you are, try selecting AT&T manually in the network settings, and keep data roaming on for the eSIM profile.
9 of our plans name T-Mobile US as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
At least one of these, LTE: B2, B4, B12, B66, B71; 5G: n25, n41, n66, n71, n77, n261, n262. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Yes. T-Mobile has run commercial 5G since 2019, on n25, n41, n66, n71, n77, n261, n262. A travel plan only gets it when the plan permits 5G, your phone supports one of those bands, and you are inside 5G coverage. Miss any one and you fall back to 4G.
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
