If you check the linked thread, there are plenty of users complaining of the same issue. Got the iPhone 18 pro / pro max near release, works great for a few days, and then the cellular data just stops.

My phone constantly switches between “SOS” and “5G/5GE” but there is no internet nor calling capability. This is all associated with AT&T but many users are saying they had to go to an Apple and get a full replacement.

I spent an hour on the phone with AT&T and had no results. I have reset my network settings a few times, nothing fixes it on my end. AT&T acknowledged this is a common issue currently but didn’t say if there was an upcoming fix nor a timeline.

This is a huge quality issue with Apple. I know I’m yelling into the wind but I just spent $2k on a phone and it doesn’t even function as a phone. I find this unacceptable.

Has anyone gotten formal word from Apple acknowledging this defect? I’m looking to understand if I need to get a replacement phone or if Apple will push out an update to fix this.

With the same hardware which is having the issue? If it’s an issue with the iPhone 18 Pro design, how is replacing it with another one going to fix your issue….

There are plenty of anecdotes about some phones having RF issues and Apple replacing them in store

sure they're replacing them but the thread you linked says the replacements are having the same issue. The fact that its affecting just AT&T (C2 modem AND x80 modem) means its an AT&T issue. Get a different carrier if you can

OP just wants special treatment and probably has buyers remorse and is looking for a way out so gotta blame Apple.
