How to use WhatsApp on two phones simultaneously

Here’s a quick and easy guide to use the same WhatsApp account on two different devices while keeping the same mobile number.

how to use one whatsapp account on two phones

Hello everyone! Frankie here again to teach you another dirty little trick to help you master WhatsApp. Today it is about using the same WhatsApp account on two devices at the same time.

More than ever, smartphones are getting, well… smarter. People rely on them for everything, so much so that often having one single cellphone or one SIM card is not enough anymore. Many people have sought out the dual-SIM smartphones, or at the very least run two separate devices for different jobs. One is used for personal affairs and one for business (or sometimes separate and very literal affairs!).

While the reasons you need two devices will vary, it begs the question: how can I use WhatsApp on two phones simultaneously? Do I need to make separate accounts for each phone number?

This article is going to show you how to do it, and you do not need to be an expert to make it happen. With a few short steps, you can have the same WhatsApp account on two different phones.

This article will examine this technique in detail. While the procedure itself is simple and quick, some explanation rarely hurt anyone. This process works on all mobile platforms (i.e. Android and iPhone).

Running WhatsApp on Two Devices with Multi-Devices Feature

Recently (July 2021), WhatsApp rolled out a new feature called Multi-Devices.

The purpose of this would be that you can then use your account on more than one phone, with a maximum of four devices synced to a single WhatsApp account. Even more, these devices did not need to stay connected to the internet for this feature to work.

That is a very beneficial feature for many users, indeed!

To use this, here is what you are going to need to do:

  1. Take the first phone linked to WhatsApp, open the service, and choose Settings
  2. Click Linked Devices and then Multi-Devices. A window then appears prompting you to scan a QR Code.
  3. On device #2, navigate to WhatsApp Web. You will need to use the ‘desktop website feature’ which I will explain in more detail below.
  4. Scan the QR Code with device #1 and wait a moment – allowing WhatsApp to transfer account data to link device #2 to your primary account.

Spy on WhatsApp with Multi Devices feature

That’s all you need to do!

If you followed these steps as I described, you will now have your WhatsApp account available on both of these devices without necessarily requiring an active internet connection.

PLEASE NOTE: You must Activate Desktop Website on your smartphone as I mentioned so that you can get these devices to sync with one another. You will need to navigate to the WhatsApp Web site and choose the ‘aA’ icon (iPhone) followed by Request Desktop Site. If on Chrome, open the menu (three dots) and choose the same option.


Frankie’s Take:

This feature is also available if you wish to add WhatsApp to devices like a tablet. So now with this feature, you can keep an active WhatsApp account on your phone and tablet simultaneously.


You might be someone that is always wishing you could have your WhatsApp across several devices, like say your work smartphone and your personal device. If you need the service across several platforms, this is sure to help.

This is also beneficial to consider how easily parents can now link a WhatsApp account to their phones to monitor conversations happening to keep their children safe.

Another benefit is how your privacy improves with this new setup. They have put time into the structure of the messaging system so that using it across several devices does not cause problems or breaches in your security.

Multi-Device Limitations You Should Know

Because this feature is still in beta, there are some limitations you should know about. Here are some of the main ones:

  1. It is not available in all countries, but it is available through most of Europe, the UK, the US, and Canada.
  2. You can link a maximum of four devices. If you’ve reached the limit and wish to connect yet another phone, you must choose to disconnect one of the ones you have started with. To do this it’s simple. Open WhatsApp from your main device, go to the Settings, and then on the option for Linked Devices. You will find a list of the phones and tablets connected to the account. Tap the one you wish to disconnect and choose Log Out.
  3. If you do not use your phone connected for more than 14 days, it will automatically disconnect.


It is time to bid you farewell, but before that happens, we should take a moment to glance back at all we have learned in this guide.

First, I showed you that you can use the same WhatsApp account on two devices with WhatsApp Web. Secondly, I explained a step-by-step approach to connect a second device to your account with the WhatsApp Web feature.

This is the best method that I know of at this point, but I should note that it is not the only possible option. You can also use the Join app. You can learn more about that in this guide I wrote about how to access WhatsApp with another phone using Join.

Hopefully this information has been helpful. Check back often to find out more new ways to use WhatsApp on more than one device. If you have comments or concerns, do not hesitate to leave them below in the comment section. I can be sure to get back with you.
