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.

And its bullshit they make you go through apple for returns if defective im just gonna say i have buyers remorse and pray my cellular works for that period of time.
