How to keep my old number in whatsapp old sim deactivated I have a new phone number and a new phone but I want to keep my old number to use in whatsapp but I don´t have that sim card anymore.
If u had a deactivated SIM card in the phone my guess is that you should still be able to use ur whatsapp through wifi. But if u have taken out the sim it is not more possible as the new sim will require a sms based validation. Better to port ur  number and then u can use it on whatsapp
