I recently reset my phone and tried to install whatsapp again.

I get this invalid number error. My number is indeed VOIP but I have been using it for 3+ years but I never faced this problem until today.

I am okay with changing my number to real one, but I need to use the whatsapp change number feature so I don't lose my conversations and people can still find me.

How do I change my number or fix this login issue?


  1. I use whatsapp web so I am still logged in the web session.

  2. I copy media/com.whatsapp before reset. I tried copying it back into my phone after the reset. But it still asks me to login. Maybe there is a way to bypass login if I have the backup?
