Did you recently get a new number for your mobile phone and want to add it to an existing WhatsApp application that uses your old number?

Of course no one would want that, as it is a privacy issue it can lead to attacks social engineering type. In order not to do all of the above, you should immediately notify the change to WhatsApp.

Βασικά, αλλάζοντας τον αριθμό τηλεφώνου μεταφέρετε όλες τις πληροφορίες του λογαριασμού σας, ομάδες και ρυθμίσεις στο νέο αριθμό. Θα πρέπει να είστε σίγουροι ότι μπορείτε να λάβετε SMS ή calls (for verification) with the new number.
