Best SIM and eSIM for El Salvador: data plans, Wi-Fi and phone tips

If your phone supports eSIM, download a prepaid eSIM from Claro, Tigo, Movistar or Digicel before arrival (or via their apps). For phones without eSIM, buy a physical SIM at San Salvador airport; bring your passport.

At El Salvador International Airport (SAL) you’ll find kiosks for Claro, Tigo, Movistar and Digicel. Prices start at $5 for 5 GB valid 30 days. In San Salvador malls (Metrocentro, Plaza Mundo) the same carriers sell prepaid cards; you must show a passport to register the number.

All four carriers support eSIM profiles that can be activated through a QR code sent by email or via their mobile apps. Activation takes a few minutes; you’ll need an internet connection for the first download, which most airports provide free Wi‑Fi.

iPhone 14 and later, Google Pixel 6+ and most Samsung Galaxy S22+ models support eSIM. Android 12+ and iOS 14+ can store multiple eSIM profiles, useful for switching back to your home carrier after travel.

If you use a physical SIM, set your APN to the carrier’s default (usually auto‑filled). Disable data roaming on your home carrier to avoid unexpected charges.

Free Wi‑Fi is common in hotels, cafés, and many restaurants in San Salvador and tourist towns like El Tunco. Public hotspots in malls and airports are also available but may require a social‑media login.

For reliable connectivity on the coast or rural Ruta de las Flores, rely on a local eSIM or SIM; signal strength is generally good in towns and along main roads.
