Will my Italian or EU SIM card offer free roaming in San Marino?

It's a common misconception, but no, your Italian or EU SIM card will not provide free roaming in San Marino. As San Marino is not a member of the European Union, the EU's "Roam Like at Home" (RLAH) regulations do not apply here. Even major Italian carriers like TIM or Vodafone IT will treat calls and data as international roaming, which can lead to surprisingly high charges. HotelESIM offers a transparent, cost-effective alternative to avoid these unexpected fees.
