Hi, I’ve recently changed my service provider, and after inserting the new sim into my iphone, I am out of reach! Yet, I can make calls and use Internet perfectly fine over LTE. When i try the new sim in another phone (android) it works fine. I have an unlocked iPhone 11, ios 14 (the latest update). I have reset network settings, updated carrier details, no blocked numbers, switched on and off airplane mode a hundred times, restarted the phone many times and I have the “do not disturb “ off. Please help me.
