WhatsApp on a tablet without a SIM: the borrowed number trick

WhatsApp on a tablet without 3G: the number you never use

Can you have WhatsApp on a tablet that has no SIM slot or mobile data connection? Yes. And the key is not in the tablet, but in an old phone that is probably gathering dust in a drawer. The procedure requires a phone number capable of receiving calls and messages, but not a smartphone: any basic handset will do, even one of those that can do little more than make calls. The tablet, however, is condemned to wifi.

The method, explained step by step in a reference guide, breaks with the idea that WhatsApp is only for high-end phones. The app is installed from Android's web browser, not from Play Store, because the official store refuses the download when it detects that the device is not compatible. A detour that, based on accumulated experience, causes no problems later on.

How to activate WhatsApp on a tablet without a SIM card

The first hurdle is verification. WhatsApp requires a phone number to send a code by SMS or call. That number does not have to be linked to the tablet or be a modern phone. All that matters is that the handset can receive the message. It is the piece many users overlook, and it makes the whole operation antiestéticasible with equipment you already have at home.

The second stumbling block appears with contacts. Without an address book the app can read, it finds no one. The solution is to link WhatsApp to a Google account and add contacts manually: a first name and the number in international format — country code included — is enough. The rest of the fields can be left empty. A more cumbersome process than on a regular phone, but it works.

The third condition is obvious and worth repeating: without 3G, the tablet will only have WhatsApp where a wifi network is available. Away from home, silence.

Emulators to run Android on Windows: Bluestacks, Genymotion and the Pidgin trick

The interest in bringing WhatsApp to bigger screens is not limited to tablets. Some people also want to run it on a Windows computer. The first option tried was Youwave, an Android emulator that worked during a trial period and then required payment. The free alternative that became popular is Bluestacks App Player, available in beta and therefore at risk of instability.

For the more technical users, there is Genymotion, an emulator compatible with Windows, Linux and macOS that is described as more stable but harder to set up. And there is an alternative route that avoids emulators: installing Pidgin on Windows, copying the lastwhatsapp.dll library and logging in with the phone number and a password obtained through specific tools in a Linux environment. A path that requires know-how and is not within everyone's reach.

Some argue that virtual machines like Youwave or Bluestacks consume a lot of system resources, which would explain why some opt for less flashy but more efficient solutions.

Can the same number be used on two devices at once?

The short answer is no. Each device needs an independent number to activate WhatsApp. If you want the app on both your phone and your tablet at the same time, you need to get a second line. For those who do not want to sign up for another SIM card, the possibility of getting a free number through services like Fonyou is mentioned.

The question of whether a landline can be used for registration was left unresolved. The available experience is limited to mobile numbers, and nobody confirmed that verification works with a landline.

In the end, the conclusion is always the same: technology allows more than the manufacturer wants you to do, but it forces you to jump through the hoop of a phone number you use for nothing else. A fine irony for a service that prides itself on being on your mobile.
