Puerto Rico eSIM Setup, Step by Step
Setting up an eSIM for Puerto Rico is the same as any destination: install at home on wifi, configure your lines, and switch the data on after you land. But Puerto Rico has one extra step that comes first, checking whether you even need one. US visitors on standard US carrier plans likely have Puerto Rico covered as domestic and can skip the whole process. This guide covers the check first, then the setup for international visitors.
Installing is not activating. And for US visitors, the step before installing is checking whether you already have coverage. Do that first.
Step zero: the US-domestic check
Before buying or installing a Puerto Rico eSIM, US visitors should confirm whether their existing plan covers Puerto Rico. Most US carriers treat it as domestic. If your plan shows Puerto Rico as domestic coverage, you do not need an eSIM and can stop reading here. If you are visiting from outside the US, or your US plan does charge for Puerto Rico, proceed to setup.
Open your carrier's app or account page, look at your coverage map or international section, and search for Puerto Rico. If it shows as included in your domestic plan, you are covered. T-Mobile, AT&T and Verizon all typically include Puerto Rico for most standard plans.
Check your phone is eligible
Your phone must support eSIM, which covers essentially every iPhone from the XS onward and most flagship and mid-range Android phones from recent years, and it must be carrier-unlocked. If you bought your phone outright or finished a contract, it is almost certainly unlocked.
Step by step: the sequence that never fails
Add the eSIM profile before you fly over a stable connection. This loads the profile but does not start your data allowance.
Name your home SIM and the Puerto Rico eSIM clearly. Set the PR eSIM as your data line and turn home-network data roaming off.
Before or just after landing, set the PR eSIM as mobile data and switch home-line data roaming off so it cannot bill you.
Enable the PR eSIM at San Juan airport. It connects to Claro, Liberty or T-Mobile Puerto Rico. Toggle data roaming on for the PR line.
A travel eSIM roams onto local networks, so data roaming must be ON for the eSIM line. Keep it OFF on your home line. The setting applies per line, not globally.
The three errors that cause almost every problem
- Roaming off on the eSIM line. Enable it. The eSIM needs roaming on to connect to Puerto Rico networks.
- Data line still set to home. Confirm the PR eSIM is selected as the mobile data line.
- Installing after landing without wifi. Install at home. Airport wifi is a fallback, not a plan.
Where we land
For international visitors, the sequence is: install at home on wifi, label lines, set PR eSIM as data with roaming on, activate on landing. For US visitors, check your carrier first. Our PR plans deliver the profile the moment you buy, so you can install at home days before departure.

FAQ
Do I need to install a Puerto Rico eSIM if I am from the US?
Probably not. Check your carrier first. Most US carriers including T-Mobile, AT&T and Verizon treat Puerto Rico as domestic coverage, meaning your existing plan works there with no extra cost. Only buy and install an eSIM if your US plan does not include Puerto Rico or charges for it there.
When should I install my Puerto Rico eSIM?
Install at home over wifi before you travel, as soon as you receive the eSIM. Installing loads the profile but does not start your data allowance. Trying to install after landing is the most common mistake because scanning the QR code needs an internet connection you do not yet have, though airport wifi can work as a fallback.
Do I need to turn on data roaming for a Puerto Rico eSIM?
Yes, for the eSIM line specifically. A travel eSIM connects to Puerto Rico networks as a roaming partner, so data roaming must be enabled for the eSIM line to work. Keep data roaming off for your home line so your home carrier cannot bill you. The setting applies per line.
Which networks does a Puerto Rico eSIM connect to?
A Puerto Rico eSIM connects to one or more of the island's three networks: Claro Puerto Rico, Liberty Puerto Rico and T-Mobile Puerto Rico. All three deliver strong 4G and 5G across San Juan and most of the island. A multi-network eSIM uses whichever has the strongest signal.
My Puerto Rico eSIM has no connection after landing. What do I check?
Check three things: data roaming is enabled for the eSIM line, the PR eSIM is selected as the mobile data line, and the eSIM line is switched on. Toggle airplane mode to force a fresh network search. If it still fails, try selecting Claro, Liberty or T-Mobile Puerto Rico manually in network settings. San Juan airport is well covered so a failure there is almost always a settings issue.
