The verdict
The verdict
Our eSIM wins when: you want to land connected for a trip of a few days to a couple of weeks, without queuing or registering a local SIM.
A local SIM wins when: you stay a month or more and want the lowest possible price per GB, and do not mind ID registration.
On the competition: Unlimited plans rarely pay off in Europe, where 5G is widespread and a capped data pack is the cheaper, smarter buy for most travellers.
Bottom line: For most travellers our eSIM is the simplest call: land connected, no queue, keep your home number. For very long stays a local pack can win on price per GB.
San Marino eSIM FAQ
Does an eSIM work in San Marino on arrival?
Yes. Activate before you fly and it connects to a local network the moment you land.
Is 4G or 5G better in San Marino in 2026?
For maps, calls and streaming 4G is already more than enough. Choose a plan on coverage and price, not on 4G versus 5G.
Is an eSIM cheaper than a local SIM in San Marino?
For short trips, usually yes once you count any markup, ID or registration hassle. For long stays a local pack can win on price per GB.
Do I need to register or show ID for the eSIM?
No. A travel eSIM needs no local registration, unlike some European SIMs that require a passport or tax ID at purchase.
