People using the new iPhone 18 Pro Max on the AT&T cellular network are running into a serious problem. The phone carrier has officially admitted that some of its users cannot make phone calls, send text messages, or use cellular data. Because these connection drops are severe enough to block emergency calls, the network provider is warning its customers to act quickly to stay safe.
The carrier asks customers to download a new software patch
To fix the network dropouts, AT&T recently sent out a direct text message to the people dealing with this problem. The company told users to get the latest iOS 27 update right away.
In its message, the network stated: “Hi, it’s AT&T. Action needed: An important Apple software update for your iPhone 18 Pro Max is available. Some phones may be unable to complete calls/text/data, including to 911. Update to iOS 27.0.1 immediately, Settings > General > Software Update. Please contact AT&T or Apple if you have questions.”

While the carrier wants users to download this patch, many people say the problem still happens even after they finish the installation. The phones often drop all signal and enter SOS mode. Interestingly, the standard iPhone 18 Pro and the brand new iPhone Duo do not seem to share this same network bug.
The phone modem might be causing the persistent connection drops
Tech watchers are noticing a difference in the parts used inside these new devices. In the United States, the largest model uses a cellular modem made by Qualcomm. The smaller models use a different modem designed by the tech giant itself.
Right now, nobody knows for sure if this specific part is causing the network drops. The phone manufacturer has not released a public statement about the situation yet. If the current update fails to solve the connection bugs, users might have to wait for another software fix to arrive in the coming weeks.
Hopefully, this is just a simple software glitch and not a permanent hardware flaw. A hardware problem would require physical repairs, which would make things much harder for everyone who bought the big new phone.
