thank you Siamless,
I had put off doing this because of all it entails. having to put all the wifi passwords and the worst, any cards in Apple Pay get deleted. still in desperation today I decided to give it a go.
Still WhatsApp does not work, if I am in the app or it is open in the background after just sending a message, the messages come through. But that is all...
Now my ordinary texts are taking forever to come through, so when I tried to verify cards in apple wallet, by the time I received the text message with the code, the time limit had expired.
so frustrating.
having to use normal texts with any friends that have a iPhone but for my boss its not possible as the same forum ( WhatsApp) is used for all his staff.
switched my phone off and on again and that didn't help either.
