This is a common misconception for travelers in Europe! San Marino is an independent republic and not part of the European Union. Therefore, your 'Roam Like at Home' benefits from an Italian or any EU-based SIM card will not apply. Using your home carrier in San Marino will incur expensive international roaming charges. For seamless and cost-effective connectivity without bill shock, an EastESIM plan specifically designed for your travel region is always the smarter choice.
HELP CENTER
If I have an Italian or other EU SIM, will roaming be free in San Marino, or should I consider an EastESIM?
