My iPhone 7 keeps losing signal since updating to iOS 14.0.1.
It goes from full signal to no signal.
My daughter's iPhone 7 iOS 13.5.1 has no issues.
Both phones are on three network.
I swapped the SIM cards the issue isn't with the SIM or network as my SIM worked fine on her phone but her SIM isn't getting a signal on my phone its a problem with iOS 14.0.1.
Hopefully Apple will fix this problem asap.
