Getting a SIM Card in Chile

The chip is easy. Your phone is the paperwork.

Chile flips the usual problem. The SIM itself — Entel, Movistar, Claro or WOM — is easy: buy prepago, register it with your passport (since 2025 the registration includes a photo check), and top up at kiosks, pharmacies and supermarkets, or in the app.

The trap is your phone. Under Chile's multibanda rules, a foreign phone works on a Chilean SIM for 30 days — then its IMEI must be registered (homologación) or the device gets blocked from Chilean networks. Staying under a month? Ignore it. Staying longer? Register early; it's free once per year and done online through authorized certifiers.

Sure. Can you pass me your passport to register it?

Aquí está. ¿Y las recargas?

Chile local tips

The 30-day IMEI rule is the whole game

Foreign phones get blocked from Chilean networks a month after first using a local SIM unless the IMEI is registered (homologación) — free once a year, done online via authorized certifiers. Under 30 days in the country: not your problem.

SIM registration is biometric now

Since 2025, buying prepago means passport plus a verification photo. Quick, but not anonymous.

Understand fast, speak slow

Chilean Spanish is LATAM's speed run: dropped esses, 'po', '¿cachái?'. Locals know it and will slow down if you ask: '¿me lo repite más lento, por favor?'

Carriers: pick by where you're going

Entel and Movistar lead overall coverage; WOM competes on cheap data in cities.

'Cargar el celu'

That's how you'll hear topping-up described; nobody is charging a battery in that sentence. Chilean voseo endings — 'pasái', 'querái', 'tenís' — are what you'll hear; the tú forms are always safe for you to produce.
