Why use a San Marino number for X (Twitter)?
Day-to-day life in San Marino runs on WhatsApp, Facebook and Instagram, yet X (Twitter) remains the app for news, brand or community accounts aimed at a local audience. A +378 number keeps that account tied to the country without using your personal SIM.
Sammarinese abroad: San Marino has a notable diaspora in the US, France and Argentina, and a local number helps them stay connected to home.
X frequently locks new or active accounts and asks for a phone code to unlock them.
