How to set up an eSIM in San Marino
eSIM activation works the same way across all carriers. The process takes under 5 minutes on a compatible phone.
Confirm eSIM compatibility
Your phone must support eSIM. Most phones released after 2020 do, including iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. Check Settings for an eSIM or digital SIM option.
Check your phone is carrier-unlocked
Some carriers lock phones to their network. If you bought your phone on contract or from a carrier store, contact them to unlock it before your trip. eSIMs from third-party providers will not work on a locked device.
Purchase your San Marino eSIM plan 1-30 days before your trip
Buy from HelloRoam, Airalo, Holafly, or another provider listed above. You can purchase 1 to 30 days before departure. Choose a plan that covers your intended stay. You receive a QR code by email within minutes of purchase.
Scan the QR code
Go to Settings > Mobile / Cellular > Add eSIM (or Add Data Plan). Point your camera at the QR code. The eSIM profile installs in about 60 seconds.
Activate on arrival in San Marino
Most plans activate when you land. Set the eSIM as your primary data line in Settings. Turn off data roaming on your home SIM to avoid unexpected charges. Run a speed test to confirm you are connected.
