Best eSIM for Puerto Rico: Plans, Prices and How to Choose
July 30th, 2026
TL;DR
The cheapest Keep On Roaming plan for Puerto Rico is the Roam Like Home® Puerto Rico 1 GB 7 Days plan at £6.00. If you measure value by price per gigabyte, the 100 GB 30 Days plan is the best of the fixed data plans at £0.85 per GB (£85.00 for 100 GB), with the 20 GB 30 Days plan close behind at £1.05 per GB. Unlimited plans start at £8.50 for a single day, so heavy users on short trips are covered too. Every plan is data only, installs by QR code before you fly, and can be topped up from your account dashboard.
What to look for in a travel eSIM for Puerto Rico
Puerto Rico rewards being connected. You will want maps for the drive out to El Yunque, translations in the smaller towns, and a working phone to book tours and taxis in San Juan. Before you buy, check four things.
Coverage for where you are actually going. City breaks and beach resorts are one thing, but if your plans include rainforest hikes or a trip to the smaller islands, make sure your provider covers Puerto Rico specifically rather than bundling it vaguely into a regional plan.
A plan length that matches your trip. There is no point paying for 30 days of data on a 5 day holiday. Look for a range that includes short validity options as well as month long ones, so you only pay for the days you will use.
Top-ups without reinstalling. Running out of data mid trip is annoying. Running out and having to buy, install and activate a whole new eSIM is worse. With Keep On Roaming, existing eSIMs can be topped up with more data from your account dashboard, without installing a new eSIM.
Installation before you fly. The best time to set up a travel eSIM is at home on your own Wi-Fi, not in an arrivals hall. Keep On Roaming plans install via QR code before you travel, and the eSIM activates when you arrive and connect.

A few honest observations. On price per gigabyte, the fixed data plans get steadily better as they grow: the 10 GB 30 Days plan works out at £1.65 per GB, the 20 GB at £1.05, the 50 GB at £0.92, and the 100 GB at £0.85. The unlimited plans cannot be compared on a per gigabyte basis, but they make sense when you would rather stream, hotspot your laptop or upload videos without thinking about a data counter.
It is also worth noticing that the 2 GB 15 Days plan and the Unlimited 1 Day plan both cost £8.50. If your trip is a single packed day of calls and content, unlimited wins. If you are on the island for a fortnight of light use, the 2 GB plan stretches much further.
Frequently asked questions
Will an eSIM work on my phone?
Most recent smartphones support eSIM, but it is worth checking before you buy. Look in your phone's settings for an option to add an eSIM or a mobile plan. If the option is there, and your phone is unlocked by your carrier, you are good to go.
When should I install my eSIM?
Install it at home, before you fly, while you have reliable Wi-Fi. You install via QR code, and the eSIM activates when you arrive in Puerto Rico and connect to a network. That way you land with data already working instead of hunting for airport Wi-Fi.
What happens if I run out of data?
You top up. Existing Keep On Roaming eSIMs can be topped up with more data from your account dashboard, and you do not need to install a new eSIM to do it.
Will my phone number change?
No. These plans are data only, so your existing SIM, number, calls and texts keep working alongside the eSIM. Friends and family can still reach you on your usual number while your data comes from the eSIM.
Do I need to do anything when I land?
Very little. If you installed the eSIM before travelling, it activates when you arrive and connect. Make sure the eSIM is selected for mobile data in your settings and you should be online within moments of switching off flight mode.
Ready to get connected?
Whether you need £6.00 of light cover for a week or a month of unlimited data, there is a plan here that fits your trip. Browse the full range of Puerto Rico plans, pick the one that matches your travel dates, and install it before you head to the airport.
