Important Roaming Notes & Tips
DANGER: San Marino is NOT in the EU despite being entirely surrounded by Italy. Your phone may silently switch to San Marino's network when visiting, and you WILL be charged international rates.
Before visiting San Marino, manually lock your phone to an Italian operator (TIM, Vodafone IT, WindTre). Your phone may auto-switch to San Marino networks without warning.
