WhatsApp: What happens to my chats if my phone number changes

WhatsApp is one of the most popular messengers for Android, iOS, Windows Phone and numerous other platforms. In contrast to SMS, where you have to pay per message or SMS Flat, where a monthly fee is due, WhatsApp only pays around 1 euro per year. The first year is even free on Android. Accordingly, you can send as many messages as you want.

WhatsApp: number changes what happens to my messages?

The scenario often happens that you get a new mobile number and then someone else gets the old one in the near future. Messages in WhatsApp are finally forwarded to that number.

WhatsApp chats are device-related

What does that mean? This means that the messages that are sent to you are on your smartphone. If you now only reset your cell phone and have not made a backup, all chats are gone, although your telephone number has remained the same.

This in turn means that if someone else receives your previous phone number, they cannot read your messages either, because chats in WhatsApp are only saved locally on the device, so that the other person cannot read the WhatsApp chats.This could be of interest to you   Our smartphone recommendations for Christmas 2019 – Find out more!
