Frequently asked questions
Why compare cost per GB?
Because two plans at the same price can include very different amounts of data. Cost per GB puts every plan on the same footing; it doesn't apply to unlimited plans, which are compared separately.
What's the cheapest eSIM for Caribbean?
Among the providers we compare, the cheapest plan for a typical trip is from Airalo, at $8.00. Prices are checked on the official websites and dated at the top of the page.
Is my phone eSIM-compatible?
Most iPhones from the XS onward, recent Samsung Galaxy phones and Google Pixels from the Pixel 3 onward are compatible. The phone also has to be unlocked. On iPhone: Settings > General > About, look for the "EID" line.
When should I install my eSIM?
Install it before you leave, on Wi-Fi, but turn on the data line when you arrive. Most plans only start at the first connection to the local network.
Do I keep my regular phone number?
Yes. Your main SIM can stay active for calls and texts; the travel eSIM only handles data. Remember to turn off data roaming on your main line.
Can I top up an eSIM in Caribbean?
Most providers let you add data from their app. Terms vary, so check the plan page before you buy.
