Samsung Galaxy A51: Can't make or receive calls or msgs, 'Failed to read data' error message

[hannahb]

Hi, I'm having a really frustrating issue with my Samsung Galaxy A51. I recently got the screen repaired with WeFix, and the said their policy is to always replace the battery. My phone worked fine until yesterday when I started noticing I couldn't call or receive calls unless they were over wifi. I've tried resetting the network settings, manually entering my network provider's AMP settings (giffgaff), force restarting

I can't access supplementary services

Error message I keep getting

Calls and messages are greyed out for some reason but mobile data is working fine??? (see below). Tried this with two different sim cards and both act the same in my phone. 

Has anyone else had this issue and managed to resolve it?
