Before you start

An unlocked handset — a carrier-locked phone will reject a Colombian SIM
Your passport, which the law requires for registering any prepaid line
Your IMEI, from *#06#
A purchase receipt for a foreign-bought handset, in case the carrier asks during IMEI registration
A cédula de extranjería for a postpaid contract or a home-internet installation

Step-by-step

1
Arrive connected with an eSIM
If your handset takes an eSIM, install a Colombia plan from Airalo, Holafly or your own carrier before you fly. Ernesto Cortissoz airport is in Soledad, about half an hour from the northern corridor, and arriving with data means you can order an app ride rather than negotiating at the rank. Plans start around US$5 and only start counting when you first connect.

2
Buy a prepago SIM at an official store
Claro, Movistar, Tigo and WOM all have stores in Buenavista, Viva Barranquilla and Centro Comercial Único, plus street-level shops all over the north. Show your passport and the clerk registers the line in your name. The SIM is free to about COP 6,000. Avoid street sellers, where both price and provenance are uncertain.

3
Register the handset's IMEI the same day
Colombia's anti-theft device database blocks unregistered foreign handsets after roughly twenty to thirty days, preceded by warning SMS in Spanish that are easy to ignore. Ask the clerk to register it at the counter: they need your passport and the IMEI from *#06#, and may ask for the phone's receipt. Activation can take a couple of business days.

4
Top up with recargas and pick a bundle
Prepaid runs on recargas bought in the carrier app, at corner shops and pharmacies showing a recarga sign, or in supermarkets. A monthly bundle typically costs COP 16,000–45,000 for roughly 10–35 GB with unlimited calls and messages, and most bundle WhatsApp traffic free. Dial *611# on Claro to check your balance and find your own number.

5
Get fibre — and shop it, because there is real competition here
Claro, Tigo and Movistar all sell symmetric fibre across the northern corridor and much of the centre, and Barranquilla is competitive enough that promotional pricing is worth negotiating rather than accepting. Coverage is patchier in the south and south-west, so check the specific address rather than the barrio. Ask the landlord which provider is already installed and test the connection during the viewing.

6
Budget for a UPS, and expect wind season outages
Fibre is only as useful as the power behind it, and Air-e's network sees localised cuts. A small uninterruptible power supply keeps the router and your laptop alive through a dip. Separately, the brisa loca from December to March genuinely dismantles poorly fixed antennas, dishes and aerial cabling, so outages cluster in those months — if you work on calls, have a mobile data fallback configured before the wind arrives, not during it.

Things most newcomers don’t know

Register your handset's IMEI the day you buy the SIM — an unregistered foreign phone stops working on Colombian networks after roughly twenty to thirty days.

Colombia maintains positive and negative IMEI databases so that stolen handsets become unusable, and a device that never enters the positive list is treated as unverified. Buying the SIM feels complete, the warning messages arrive in Spanish, and the block lands in the week you finally need the phone to work.

Home internet outages cluster from December to March, and the cause is wind rather than the network.

The brisa loca reaches speeds that strip aerial cabling, misalign dishes and loosen rooftop fixings, so a run of drops in January says more about your building's installation than about your provider. Ask a prospective landlord whether the drop cable and any external equipment were re-secured after the last wind season, and keep a mobile hotspot configured as a fallback rather than discovering the need mid-call.

Prepaid needs only a passport; postpaid needs a cédula, credit history and usually a Colombian bank account.

Your first months are prepago whether you like it or not, and the subsidised handsets and best data plans sit behind pospago. Knowing this in advance saves a wasted store visit trying to negotiate a bundled phone before your cédula exists.

Fibre coverage here is a per-address question with a sharp north-south gradient, not a per-city one.

The northern corridor has three providers competing on symmetric gigabit; parts of the south-west have one, on copper, or none. Because Barranquilla is generally described as well-connected, newcomers sign leases on the strength of the city's reputation and discover the gap after moving. Test the actual flat during the viewing and ask which provider's cable is already at the building.

Common mistakes to avoid

Skipping IMEI registration and losing network access three or four weeks in.
Signing a lease in the south or south-west on the assumption that Barranquilla's fibre reputation applies to every address.
Working from home over fibre with no UPS and no mobile fallback through the December-to-March wind season.
Buying a SIM from a street seller rather than an official store.
Accepting the first fibre price quoted, in a city where three providers actively compete for the same building.
