During the night, my phone (15 Pro) was updated to iOS 18 beta 4, but since then the mobile internet does not work (only EDGE, or not at all) and it also throws away the SIM card. Does anyone else have this problem? Do you already know if this error is being fixed?
Same problem for me. Also wi-fi connection works perfectly fine. Major bug, few hour and it will be fixed.
