Will my phone work with a Saint Martin eSIM?

Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3+, and recent Samsung Galaxy S/Z models. Your phone must be carrier-unlocked.

Does the Saint Martin eSIM include 5G?

Yes — our Saint Martin plans connect to 5G where the local network supports it, and fall back to 4G/LTE automatically.

Can I keep my own phone number?

Yes. The eSIM runs as a separate data line, so you keep your main number for calls and texts while using Saint Martin data on the eSIM.

When does my plan start?

Your validity begins when the eSIM first connects to a network in Saint Martin, so you can install it before you travel and it won't start counting down until you arrive.
