No! This is the #1 roaming trap in Europe. San Marino is NOT a member of the European Union (EU). Your EU "Roam Like at Home" (RLAH) plan will not work, and your home carrier (even Italian ones like TIM or Vodafone IT) will charge you extremely high international roaming fees (up to €15 per MB) the moment you connect to a San Marino network. A eSIMBuy eSIM is the only way to avoid this massive bill shock.
