Installing WhatsApp on your phone: a step-by-step guide, no jargon

Your children keep saying “message me on WhatsApp”, your sister in France sends her photos that way, and the family group lives on it. You don’t have it on your phone yet — and you are not quite sure where to start.

This is not a silly place to be: installing an app is far from obvious the first time, and the fear of “doing something wrong” holds a lot of people back. Give yourself twenty minutes, once, and it is done for good.

What you need before you start

• Your phone and your home Wi-Fi: it is faster, and it does not eat into your mobile data.
• Your phone number: it is what identifies you. There is no new password to invent.
• The password for your Apple account (iPhone) or Google account (Android). That is the only moment you will be asked for it. If you no longer have it at hand, set it aside: you will need to recover it before going further.

Installing WhatsApp, step by step

1. Open your phone’s app store: the blue “App Store” icon on an iPhone or iPad, the colourful triangle-shaped “Play Store” icon on an Android device (Samsung, Google, Motorola and so on).
2. Tap the “Search” magnifying glass, then type whatsapp. Capital letters make no difference.
3. Look at the result before tapping anything: the right one has a green icon with a white handset, is called exactly “WhatsApp Messenger”, and lists WhatsApp Inc. as the publisher. The apps with similar names, just below, are not the one.
4. Tap “Get” or “Install”. The phone may ask for your password, your fingerprint or your face: that is normal, it is how it checks that it really is you.
5. Wait until the button turns into “Open”, then tap it. The green icon is now on your home screen too, along with the others.
6. WhatsApp asks for your number. Choose Canada (+1), enter your ten digits with no dashes, and read them back before confirming.
7. A text message arrives with a six-digit code: type it into WhatsApp. If it is slow to come, wait a minute before asking for another one.
8. Finally, write your first name — that is what your family will see — and, if you are asked, allow WhatsApp to see your contacts. Without that, your address book stays empty inside the app.

The six-digit code: the one rule to remember

That code belongs to you alone, and nobody has a good reason to ask you for it. If a “friend” writes that they mistyped their number and asks you to forward the code you have just received, it is a scam: the message comes from someone trying to get into your account, not from your friend. Do not reply, and delete it. The Canadian Anti-Fraud Centre receives that report all year round, and nobody is foolish for having run into it.

Does it cost anything?

No. The app is free, there is no subscription, and both messages and calls travel over the internet rather than through your plan’s minutes. At home, on your Vidéotron or Bell Wi-Fi, calling Marseille or Port-au-Prince costs nothing beyond the internet you already pay for. Out of the house, your mobile data is used instead: text is negligible, a long video call somewhat less so.

Once it is installed

Start small: write to one person and watch them reply. When you feel comfortable, the camera button at the top of the conversation starts a video call — the full path is set out in our article on video calling your grandchildren.

And if you would rather do this first installation with someone beside you than alone in front of the screen, that is exactly the kind of house call we make, across the Montreal neighbourhoods we serve, from Verdun to Ahuntsic. In one visit the app is installed, set up, and you have called someone for real.
