Question 1

When does my St. Martin eSIM plan start?

Accepted Answer

Install on Wi-Fi before you travel. Validity usually starts when the eSIM first connects to a network in a covered area — typically when you land.

Question 2

Will I get roaming fees from my home carrier?

Accepted Answer

Not if you use this eSIM for mobile data and leave home-line data roaming off. Your home number can stay active for calls and SMS.

Question 3

What if I run out of data?

Accepted Answer

Choose a plan marked Top-up when available — you can recharge from your account without a new QR. Otherwise buy another plan for the same destination.

Question 4

How do I install the eSIM?

Accepted Answer

After payment confirmation you get a QR code by email. Scan it in phone Settings → Cellular / SIMs → Add eSIM. See our install guide for iPhone and Android steps.
