Liberty Mobile and travel eSIM in Puerto Rico

Quick answer

  • 7 of the 36 Puerto Rico plans we sell name Liberty Mobile as a reachable network, at 4G.
  • Travel plans connect by roaming, so no plan can promise one specific network.

Liberty Mobile in brief

Liberty Puerto Rico operates under MCC-MNC 313-790 and switched off its UMTS 3G network on 22 February 2022, leaving LTE and 5G.

We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.

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 Liberty 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.

Who licenses Liberty Mobile

Mobile networks in Puerto Rico 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.

The plans on our shelf that name Liberty Mobile

From the supplier record behind each package, 7 of the 36 plans we currently sell for Puerto Rico declare Liberty Mobile as a network the profile can reach, at 4G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.

A plan naming Liberty Mobile means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order is the supplier's, and the signal where you stand decides.

Why plans do not name a fixed network

Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Liberty Mobile is weak where you are, try selecting T-Mobile US manually in the network settings, and keep data roaming on for the eSIM profile.

FAQ

Will my eSIM definitely connect to Liberty Mobile?+

7 of our plans name Liberty Mobile 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.

Does Liberty Mobile run 5G, and will my plan get it?+

Yes. Liberty Mobile has run commercial 5G. 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.

How do I see which network I am on?+

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.
