Before you choose

Four checks for a plan that fits your trip.

Data for the whole trip or per day?
10 GB total is one allowance for the package. 1 GB/day is a daily allowance. Check the reset rules and what happens after the allowance: slower data, extra charges or no connection.
When does validity start?
Installation and activation can be separate steps. Check whether the clock starts at purchase, installation or first connection. Choose enough valid days for your stay.
Where can you connect?
Check every country on your route and the networks listed for the exact package. A country in the coverage list does not guarantee a signal everywhere.
Will it work for your setup?
Check that your phone supports eSIM and is carrier-unlocked. If you need laptop data, verify hotspot permission. Confirm any calls, texts or phone number separately.

Frequently Asked Questions about eSIM for San Marino

What is an eSIM and how does it work?

An eSIM (embedded SIM) is a digital SIM card built into your smartphone. Instead of inserting a physical chip, you scan a QR code or download a profile to connect to a mobile network in San Marino. It works exactly like a regular SIM for data but without swapping cards.

Is my phone compatible with eSIM?

Most newer smartphones support eSIM, including iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and many more. Check your phone settings or manufacturer website to confirm eSIM compatibility.

Can I keep my WhatsApp number?

Yes! Your WhatsApp account is linked to your phone number, not your SIM card. When you activate your eSIM data in San Marino, WhatsApp will continue working exactly as before.

When should I activate my eSIM?

Most eSIM providers recommend installing the eSIM before your trip while you still have a stable Wi-Fi connection. The data plan usually starts counting when you first connect to a network in San Marino.
