I got a new iPhone 12 a few weeks ago and at the same time changed my provider from O2 to iD. I transferred my old number to my new phone.
There are two problems: 1) When I text an android phone it comes up on my phone as Not Delivered. But the person I’m texting receives the text 3 times.
2) Sometimes when I call or text someone, the number shown on the phone of the person receiving it shows up as the new number given to me with my new contract (which I’m not using) instead of the old one that I transferred.
I hope all that makes sense. I’d very much appreciate some advice as it’s driving me mad!
