I recently had a problem with my Samsung S7 edge. It keeps on restarting and after removing cache, it still restarts after a few minutes. I found out that the most effective way to fix it is a factory reset. The problem is that, I am overseas and I could not receive any calls or text. Hence, I would not be able to verify my Whatsapp number.

Does anyone know whether Whatsapp requires verification after factory reset or does anyone know how to fix the problem?

Thank you!

  • Yes it does. You'll need to input the code sent to your phone number

  • An alternative way would be to ask someone to forward the code to you if you left your SIM card home.

Yes it will require verification, and you will need to be able to receive a text to verify your number with WhatsApp. If your device/carrier has the ability to send/receive texts over wifi, that may be an option for you to verify your number.

Per WhatsApp's FAQ Page here:


  • You can only verify a phone number you own.
  • You must be able to receive phone calls and SMS to the phone number you are trying to verify.
  • You must have any call-blocking settings, apps or task killers disabled.
  • You must have a working Internet connection through mobile data or Wi-Fi. If you are roaming or have a bad connection, verification may not work. Try opening www.whatsapp.com on your phone’s Internet browser to see if you are connected to the Internet.

If you didn't receive the 6-digit code by SMS

  • If the timer runs out before you receive the code, an option will appear to request a phone call. Choose the Call me option to request the call. When you answer the call, an automated voice should tell you the 6-digit code. Insert that to verify WhatsApp.
