Before you start

CPF
Unlocked or eSIM-capable handset
A Belo Horizonte 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 any pressure to sign something unsuitable in week one.

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, and there is no anonymous option in Brazil.

3
Test coverage at the actual flat, on the actual hill
Signal in the steeper parts of Santa Tereza, Serra, Mangabeiras and the northern hills varies street by street and floor by floor. Stand in the room you will work in and check, rather than trusting a coverage map drawn at neighbourhood resolution.

Compare regional fibre providers as well as the national ones
Alongside Vivo Fibra and Claro there is a competitive field of regional operators in Minas, and they frequently offer better speeds for less. Ask neighbours or the building porter which provider actually performs in the block.

5
Check what is already cabled into the building
Riser space is finite and síndicos sign arrangements with particular operators, so a well-served street can be a poorly served block. The porteiro answers this in thirty seconds.

Register on Celular Seguro
The federal service lets you or a nominated contact block a stolen handset and its banking apps across every operator at once. Register through gov.br before you need it.

Things most newcomers don’t know

Topography, not the operator, is what determines mobile coverage here.

Belo Horizonte sits in a bowl ringed by hills, and the steep districts — Santa Tereza's upper streets, the Serra, parts of Mangabeiras and the northern slopes — have shadowed pockets that behave the same on every network. Switching operator does not fix it. Test the signal standing in the room you will actually work in, on the floor you will actually live on.

Regional fibre providers in Minas frequently beat the national carriers.

A competitive local ISP market has grown across the state and those operators often sell symmetric connections below what the national brands charge for asymmetric ones. Newcomers default to the brand they recognise from advertising. Asking three neighbours which provider they use gives a more reliable answer than any coverage map, and the answer is usually consistent within a building.

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. A foreigner without one can activate in a company store on a passport, but that is the only counter that will do it. The bank then wants the number for two-factor codes and the landlord wants the bank, so the practical sequence stays CPF, chip, bank, lease.

Celular Seguro blocks the phone and the banking apps in one action, but only if pre-registered.

Handset theft in Brazil is organised around the banking apps rather than the hardware, so the gap between losing a phone and losing money is short. The federal service triggers a block across every operator and participating bank at once — and registration takes a few minutes through gov.br, which almost nobody does until after something happens.

Common mistakes to avoid

Expecting to pick up an unregistered chip in a supermarket before the CPF exists.
Trusting a neighbourhood coverage map in a city built on hills.
Defaulting to a national carrier for fibre without checking regional providers.
Signing a lease for remote work without confirming which operators reach the building.
Registering on Celular Seguro only after a theft.
