Here's how to use WhatsApp without a SIM card in your phone
Published onFebruary 19, 2025
WhatsApp is great, but it has one major limitation: it requires a mobile phone number to work. Thankfully, there are a few ways to use WhatsApp without a SIM card.
These methods require you to download WhatsApp on your device, either via the Google Play Store, Apple App Store, or directly from WhatsApp’s official website. If you choose the second method, be sure to check out our guide for installing apps without the Google Play Store.
QUICK ANSWER
You can use WhatsApp without a SIM by verifying your account using another device's phone number. To do this, download WhatsApp on your phone without a SIM and enter your other phone's number during the setup process. When WhatsApp sends you a message with the verification code, enter it into the phone without a SIM card.
You can also accomplish this using a landline phone. You'll just have to request a call, instead of a text message. Alternatively, you can use an SMS or VOIP app. Additionally, there is now a way to use secondary devices as companion devices for WhatsApp. Keep reading for more details.

Use a virtual phone number and texting app
Sadly, not everyone has access to a secondary cellphone or landline number. You might still want to use WhatsApp without a SIM card, though.
If you really can’t get a hold of any phone number for a call or text verification, but have access to an internet connection, you can use a third-party app. Some applications grant you a virtual phone number, as well as calling and texting capabilities. Some of them are free, too! A very popular one is Google Voice, but there are great alternatives. Here’s a list of our favorite free text apps.
Once you have a phone number, simply follow the same steps above to sign up for WhatsApp, but use your VOIP number instead.
Use your phone without a SIM card as a linked device
Did you know you can officially have the same WhatsApp account on multiple devices? You will need a primary device, and then you can have up to four linked devices that can also access the same WhatsApp account. All devices will be logged out if the primary device doesn’t connect in 14 days.
This is a good option if you actually have a primary device with WhatsApp, and you want to use your phone with no SIM card as a secondary WhatsApp handset.

FAQs
As long as WhatsApp supports the country, you can use a number from that region to use WhatsApp. Very few countries have banned the use of WhatsApp, including China, North Korea, Syria, Qatar, and the United Arab Emirates.
You can use a single number on a primary device, as well as four linked devices. However, only one WhatsApp account can be linked to a phone number. This means that if you’re using a landline, only one person from that household will be able to use that phone number to create a WhatsApp account.
Yes. You’ll need to link the personal and business accounts to different numbers.
You can’t use WhatsApp on a Windows or macOS computer alone, but you can use WhatsApp Web to link your WhatsApp account to a browser and use it remotely. Everything still runs through your phone, though.
WhatsApp needs to verify a phone number to work, but it doesn’t necessarily need to be the number linked to a SIM card installed on the same phone. This means you can use WhatsApp on a phone without a SIM card as long as you can verify it with another active device, or if you use the secondary phone as a linked device.
Sadly, if you’ve lost access to an old number, you won’t be able to verify it on WhatsApp. You need to get a code via a call or a text message. This is a mandatory step. The only option would be to create a new WhatsApp account.
WhatsApp uses calls and texts for verification, but this is mostly for security reasons. The service, itself, relies solely on data. You don’t necessarily need cell service to use WhatsApp; you need data. This includes both cellular and Wi-Fi data, so you could use a phone without cell service as long as you’re connected to Wi-Fi.
