I have recently upgraded my iPhone 7 to an iPhone XR and am using the same SIM card. I’ve recently found an issue I did not experience with my iPhone 7, my phone will show it has plenty of 4G and it will work perfect for around 30/45 minutes then suddenly the connection stops despite still having 4G. It starts to work again when I turn my phone on and off but I’ve not found a solution to stop this issue completely. I’ve never had an issue with this sim before and yes I have reset my network settings! Is this a issue with the phone itself? I’d appreciate any help thank you!
