Recently acquired a Galaxy S20 on EE and previously I was on 3 with my S8, I had my number transferred across from 3 to EE but in the settings and other apps it still has the temporary number that was given by EE showing, however the texts and calls are showing up as my proper number, I can't find a way to change it. Any help is greatly appreciated.
the only way I've managed to get this to work is by putting my SIM in an iPhone and changing it there. Its a bit ridiculous that we have to do that. I even got a replacement sim once I'd transferred and even that didn't work. everything kept defaulting to the original number that I didn't keep, and so RCS/chat didn't work.
