Colombian Phone Number for US Expats: Complete Guide

You moved to Colombia — or you spend months here each year — and quickly discovered that everything runs on your local number. It's not optional infrastructure; it's mandatory.

• Nequi and DaviPlata — Colombia's dominant mobile wallets require an active Colombian number. No number, no account.
• Banking 2FA — Bancolombia, Davivienda, and BBVA send verification codes via SMS to your Colombian line.
• WhatsApp — your Colombian contacts, building groups, and service providers know you by your local number.
• Delivery apps — Rappi, iFood, InDrive all verify via Colombian SMS.
• Local credibility — a +57 number signals you live here. A +1 number signals tourist pricing.

Colombian prepaid SIMs require in-person purchase with valid ID. As a US citizen, you need:

• Your passport (the physical document, not a copy)
• A carrier store or authorized dealer — Claro, Tigo, or Movistar offices in any major city

The process takes 15-60 minutes depending on the store and line. You'll leave with an active number and a basic balance. SIM cost is negligible (often free with a plan purchase).

Where to go:

• Claro — largest carrier, offices in every mall and city center
• Tigo — look for orange storefronts, strong in urban areas
• Movistar — blue storefronts, good international calling options

Avoid buying SIMs from street vendors — registration may not be completed properly, causing issues later.

This is where most Americans run into trouble. You get the SIM while in Colombia. Everything works great. Then you fly home to the US, and 60 days later your number starts dying.

CRC Resolution 5050/2016 allows carriers to deactivate prepaid numbers after 60 days without a refill or outgoing cellular activity. WiFi usage doesn't count. Making calls over WiFi doesn't count. Only a balance refill or activity on the Colombian carrier network resets the clock.

From the US, your options for refilling are limited:

• Carrier apps (Mi Claro, Mi Tigo, Mi Movistar) — reject all US-issued cards
• Tiendas — require being physically in Colombia
• NomadSIM — accepts US cards, delivers refills remotely, supports auto-scheduling

Every Colombian carrier app rejects foreign-issued credit and debit cards. This is the single biggest pain point for Americans with Colombian numbers.

A verified 2024 review on Mi Claro's Google Play listing: "No international credit cards are accepted… It's 2024, I shouldn't have to walk into a point of sale to recharge service." Claro's own support team replied without offering a solution.

The TripAdvisor Colombia forum confirms: "ETB is the only provider that will let me top up or pay my account with a foreign card." But ETB has minimal prepaid market share — 90%+ of expats are on Claro, Tigo, or Movistar.

This means 20+ million Americans who visit or live in Colombia part-time have no direct way to refill their numbers from US soil using their US bank cards.

NomadSIM exists because of this exact problem. The service:

1. Accepts any US or international credit/debit card (via Stripe)
2. Delivers refills to Claro, Tigo, and Movistar prepaid numbers
3. Supports one-time refills or recurring auto-refill on your schedule
4. Offers Keep My Number ($2.50/60 days) to prevent deactivation while you're in the US
5. Lets you pre-set a return date — subscription auto-cancels when you're back in Colombia

No more asking your Colombian friend to walk to a tienda. No more Zelle-ing someone $10 and hoping they remember. Set it once, forget it, and your number is alive when you land.
