Before you start

CPF
Unlocked or eSIM-capable handset
A Salvador address, for fibre and postpaid
A Brazilian payment method, for postpaid direct debit

Step-by-step

1
Bridge the first days with a travel eSIM
A data eSIM bought before arrival covers the gap until the CPF-registered chip is in place and removes the pressure to sign something unsuitable at the airport.

2
Buy a prepaid chip against your CPF
Operator stores in the shopping centres, supermarkets and lottery agents all sell them, registered at the counter to a named holder — name, address, date of birth and CPF for an individual. Without a CPF you can still activate inside an operator's own store on a passport or RNM, but nowhere else will.

3
Register on Celular Seguro before you need it
The federal service lets you or a nominated contact block a stolen handset and its banking apps across all operators at once. Registration takes minutes through gov.br and only works if it was done in advance. Do this in your first week here, not your first month.

4
Check what is already cabled into the building
Riser space is finite and síndicos sign arrangements with particular providers, so a street with five operators can be a building with two. Salvador's older blocks in Barra, Graça and the historic districts are the ones where this bites. The porteiro knows the answer in thirty seconds.

5
Ask neighbours which provider actually performs
Advertised coverage maps and delivered speed diverge here more than in the southern capitals. Two people in the same building will give you a consistent answer; a coverage map will not.

6
Move to postpaid once a credit file exists
Postpaid offers better data value but runs a credit check against a CPF that starts empty. Expect a few months on prepaid, or ask whether the operator will take a deposit.

Things most newcomers don’t know

Celular Seguro blocks the phone and the banking apps in one action, and it must be set up in advance.

Handset theft in Brazil targets the banking apps rather than the hardware, so the gap between losing a phone and losing money is short. The federal service lets you or a nominated contact trigger a block across every operator and participating bank at once — but only if you registered beforehand. In Salvador this is the highest-return five minutes of admin in your first week.

There is no anonymous SIM in Brazil, which fixes the order of your first fortnight.

Lei 10.703/2003 and art. 58 of ANATEL's Resolução 477/2007 require every chip including prepaid to be registered to an identified holder, with the CPF recorded for individuals. The bank then needs the number for two-factor codes and the landlord needs the bank, so the practical sequence stays CPF, chip, bank, lease.

The condominium, not the street, decides which fibre you can have.

Buildings have finite riser capacity and síndicos sign exclusivity-flavoured arrangements with particular operators. A well-served street can be a badly served block, and Salvador's older mid-century stock in the central districts is where this is most common. If your income depends on the connection, ask the porter which operators already have cable inside before you sign a lease.

Keep a second, cheap handset if you will be out at night regularly.

This is folklore rather than regulation, but it is close to universal practice among residents of Brazil's higher-crime capitals and it is worth stating plainly: an old phone with the chip moved into it, and the banking apps left off, converts a robbery from a financial event into an inconvenience. Combine it with Celular Seguro and low Pix limits and the exposure is small.

Common mistakes to avoid

Expecting to pick up an unregistered chip in a supermarket before the CPF exists.
Registering on Celular Seguro only after a theft.
Signing a lease for remote work without confirming which operators reach the building.
Trusting an advertised coverage map over what two neighbours tell you.
Applying for postpaid on an empty Brazilian credit file and being declined.
