Many iPhone 12 Users Experiencing Problematic 5G, LTE Service

With the release of the iPhone 12 line, Apple finally brought 5G connectivity to its smartphones. 5G is a new technology that provides much faster connection speeds.

However, 5G hasn’t been adopted everywhere yet. Many carriers have been pushing for more 5G coverage, but even in areas with 5G coverage, it seems the iPhone 12 has connection issues.

As seen on Apple’s community forums, users like joxesCA report problems with their iPhone 12 connecting to 5G and LTE. After activating the device, joxesCA’s iPhone stopped displaying service bars and showed a message saying, “Your iPhone is not Activated.”

He could get the connection back by toggling the Airplane mode on then off, but the issue kept recurring even after factory resetting the phone.

Received my iPhone 12 Pro on Friday. Activated it on Saturday. Sunday I drove for 10 mns and when I arrive to my destination I saw no reception bars and No Service. And in the middle of the screen in a grey box: Your iPhone is not Activated. The only way to get the connection back was to toggle Airplane mode to ON then OFF. The iPhone had the cellular mode to 5G Auto. I switched it to LTE to test. And it was the same. So I resetted the network settings: same issue and I resetted the iPhone as a new iPhone and reinstalled everything from scratch (not from a saved backup): same issue. I drove my car and found the exact location where the phone lost the network. If the phone lost the network it means I reach the end of the coverage area from a certain antenna. It looks like something happened with the phone when I reach a zone covered by a new antenna. I called my operator and they told me that everything is good on their end and I have the right SIM card for a 5G device. I called the Apple Tech Support and they remotely installed on my phone [Baseband and Telephony Logging and CFNetwork Diagnostics profiles] I was able to replicate the issue after talking to the Apple Tech and I was able to submit the report. I pushed a little bit the research and I found on Reddit a lot of people talking about the same issue not only on Verizon (my carrier) but also on AT&T. Just use the title I typed and you will find the article. I never had such issue with the 11pro.

This is an issue experienced by many other users on Reddit who are provided cellular service by AT&T and Verizon.

A couple of users on T-Mobile have said they have been experiencing similar problems, but it seems to be an issue with the implementation of 5G and LTE in some new iPhones.
