So I ordered my upgrade, iPhone 13 pro max 26/7, within 5 hours my existing iPhone 11 lost the ability to make calls, but would receive calls, and able to use data. I rang customer service (work phone) and was told they had accidentally activated the new sim, and said they would reverse it. It hasn't worked since, but does show 4g network.
Today 27/7 my new phone, and sim leaflet arrived. It took several goes before the sim process worked, a text was received on the iPhone 11 telling me it had gone through, BUT, there is no network signal, it only operates on wifi. It won't let me activate wifi calling either - is this 5G related??
I cannot call O2 because I don't have a home landline, and neither the 11 or 13 can make calls.
Do I just need to wait? I'm not convinced everything is right on the network relating to the number and sim allocation.
