When you arrive in Brazil, you will quickly notice a difference in the way people communicate: WhatsApp is everywhere.
In Europe, we were mainly accustomed to using it to talk to family, friends or in certain groups. In Brazil, it is also a genuine everyday tool for communicating with businesses, professionals and many different services.
Booking an appointment, asking for a price, sending your location, receiving a quotation, sharing a document, contacting an estate agent or placing an order: many conversations that might take place by telephone or email elsewhere happen here directly through WhatsApp.
For anyone coming to live in Brazil, adopting it quickly therefore makes everyday life considerably easier.

WhatsApp is part of everyday life in Brazil
Asking “Qual é o seu WhatsApp?” — “What's your WhatsApp?” is perfectly normal in Brazil.
WhatsApp buttons appear on many websites, Instagram profiles and business pages. Rather than looking for an email address or making a telephone call, the natural first step is often simply to send a WhatsApp message.
The app brings together text, photos, videos, documents, locations and voice messages in a single conversation. It is particularly efficient for explaining a problem to a tradesperson, arranging a property viewing or sending an address.
Groups are also important: family, condominium, school, neighbourhood, associations, activities and work. A considerable amount of practical information can circulate through them.
Voice messages have a particular importance
Voice messages are extremely common.
They are quick, avoid having to type a long message on a phone and allow people who are less comfortable with reading or writing to communicate much more easily. In a country as large and socially diverse as Brazil, this simplicity contributes to their widespread use.
For a foreign national who is still learning Portuguese, this can initially be somewhat challenging: understanding a written message is often easier than following a rapidly spoken voice message.
You soon become accustomed to them, however. A message can be replayed, and recent versions of WhatsApp also offer voice-message transcription features, depending on the supported language and device.
In Brazil, calls also use mobile data
Another important difference concerns the way mobile plans are used.
In Brazil, WhatsApp audio and video calls use an internet connection rather than the minutes of a traditional telephone call. Mobile operators offer plans in which WhatsApp often plays an important role, with some offers allowing its use without deducting all or part of the data allowance, depending on the particular plan.
In practice, this helps make traditional telephone calls much less essential for many users.
There is another reason for preferring WhatsApp: conventional telephone lines can receive large numbers of telemarketing and unwanted calls. WhatsApp provides more options for identifying, blocking or filtering certain contacts and calls.
Having a reliable data connection can therefore become more important than having a large allowance of traditional call minutes.
Do you need a Brazilian number?
You can continue using the WhatsApp account associated with your European number when you arrive in Brazil. There is no need to change the number associated with your WhatsApp account immediately.
However, continuing to use your European operator's mobile data while roaming can become expensive, depending on your plan.
A very practical solution is to keep your European number and add a Brazilian line, particularly if your phone supports Dual SIM or eSIM.
Your European number can remain active for WhatsApp, your existing contacts, banks or European services that still send verification codes. The Brazilian line can then provide the mobile data you use every day.
WhatsApp simply uses whichever internet connection is available on the phone. The data from your Brazilian line can therefore be used by a WhatsApp account that remains associated with your European number.
Later, you can decide whether you want to change the number associated with WhatsApp.
A Brazilian number nevertheless becomes useful for another reason: some Brazilian forms and services expect a number in the national format and do not always allow a foreign number to be entered correctly.
It is therefore useful to distinguish between two things:
the number associated with your WhatsApp account and the line providing your mobile data.
They do not necessarily have to be the same.
WhatsApp Business: much more than a simple chat
For businesses, WhatsApp goes far beyond a conversation between two phones.
WhatsApp Business allows professionals to organise customer relationships, present their business and use a range of commercial tools.
More structured companies can go considerably further, using systems in which several people handle conversations, enquiries are routed to different departments and some initial responses can be automated.
Artificial intelligence is also beginning to be incorporated into these customer journeys: qualifying an enquiry, providing an initial response, collecting information or directing the customer to the appropriate person before a human operator eventually takes over the conversation.
For the customer, all of this can remain almost invisible: they simply send a message to a WhatsApp number. Behind that number, however, there may be a complete customer-service system, rather than a phone sitting on an employee's desk.
This helps explain why WhatsApp has become such an important commercial channel in Brazil.

Be alert to scams
An app used on such a large scale naturally also attracts fraud attempts.
A profile displaying the photograph of someone you know or the name of a company does not guarantee that you are actually communicating with that person or business. Fraudsters may use fake profiles, compromised accounts or create a sense of urgency to obtain a payment.
A few precautions are particularly important: verify an unusual request through another channel, check the recipient carefully before making a Pix payment, never share codes that could be used to activate your WhatsApp account, and enable the security protections available in the app.
Two-step verification is particularly recommended.

WhatsApp makes communication considerably easier, but a conversation does not automatically replace a contract, signature or formal procedure when one is required.
An almost essential tool in Brazil
There is, of course, no requirement to use WhatsApp to live in Brazil. In practice, however, not using it would make many everyday situations unnecessarily complicated.
Perhaps the biggest adjustment for a new arrival is understanding that it is not merely a private messaging app. It is simultaneously a way to communicate, make calls, exchange documents, participate in groups and contact professionals or businesses.
And if you arrive with a European number, there is no need to change everything on your first day: keep your old number if you still need it and use a Brazilian line for mobile data and local services. You can organise the transition gradually.
After spending some time in Brazil, contacting a business through WhatsApp rather than searching for its email address simply becomes second nature.
