Hello, I have an Iphone 12 pro for awhile now, and have been using the 4G LTE Network Extender for years. But recently my phone calls have either been just dropped or I cannot make a phone call at all. I have rebooted, I have toggled between airplane mode and back, but that is just a temporary solution. I thought it might be my 5G phone, but I have that for over 2 years now. Any help would be greatly appreciated.
