I've had 4G LTE on my iPhone 7+ in my area for years now and it worked perfectly. Ever since Verizon has been rolling out 5G service, my 4G LTE service has degraded to the point it is almost unusable now. The only "solution" I've gotten is to upgrade my phone when I know for a fact it isn't my phone that's the problem, its the service. I still pay for this service every month, but I'm very likely to switch carriers soon due to this.
Oh, no! Dealing with service issues can certainly be a headache, especially if the signal in degrading. The last thing we want is for you to switch. Please send us a Private Note to better assist you. ~Gilbert
