There are now patches to apply if you don't have any problems making calls on an AT&T iPhone 18 Pro Max . If you do, you need to get your phone replaced. iPhone 18 Pro Max Since launch, iPhone 18 Pro Max models have been dropping off the AT&T network. In some cases, never to return. After an OS update earlier in the week, and a carrier settings update on Friday, the problem may no longer manifest for those who haven't seen it. But, that doesn't help if your iPhone has issues already. Continue Reading on AppleInsider | Discuss on our Forums
AT&T and Apple are taking action today as they try to resolve iPhone 18 Pro Max cellular issues, according to MacRumors contributor Aaron Perris. Thousands of iPhone 18 Pro Max users have been unable to connect to the AT&T network for phone calls, text messages, and data. The underlying cause has yet to be disclosed, but AT&T and Apple continue to work toward a resolution. First, Apple today released an AT&T carrier settings update (version 72.1, up from 72.0.2) for iPhones. Given the timing of this update, it presumably includes some optimizations related to iPhone 18 Pro Max cellular connectivity, but it is unclear if AT&T has fully resolved the issues or if further tweaks will be necessary. When a carrier settings update is available on your iPhone, you will be prompted to install it. If you dismiss the notification or do not see it, open the Settings app, tap General → About, and the update should appear there. You can see your iPhone's current carrier settings version in the same About menu, next to your carrier's name. Second, Apple today started requiring iPhone 18 Pro Max users to install iOS 27.0.1 in order to set up the device, even though most if not all affected users have said that the update does not resolve the issues. A leaked AT&T email said iOS 27.0.1 is meant to help mitigate future impacts, so it may still help in some way. In a statement shared with MacRumors today, AT&T said it is "working with Apple" on this. Apple did not respond to our request for comment. It is not yet clear if a follow-up update like iOS 27.0.2 will be required as part of a fix, or if the carrier update alone will be sufficient.

In a statement shared with MacRumors today, AT&T said it is "working with Apple" to resolve iPhone 18 Pro Max cellular issues. "Apple has released a software update to address an issue that may affect calls, data, texts, and 911 calls on a small number of Apple iPhone 18 Pro Max phones," an AT&T spokesperson said. "AT&T customers with an iPhone 18 Pro Max should update their phones now to the latest available software. Our top priority is ensuring customers can stay connected when they need it most, and we are working with Apple to make it right." As we reported last week , affected iPhone 18 Pro Max users are unable to connect to the AT&T network for phone calls, text messages, or data either persistently or intermittently, and their devices typically enter SOS mode as a result. The underlying cause has not been confirmed, and Apple has yet to publicly comment on the matter. Thousands of users have experienced this problem since the iPhone 18 Pro Max launched on September 18, according to discussion threads across the Apple Support Community , Reddit , MacRumors Forums , and other online platforms. Notably, the U.S. version of the iPhone 18 Pro Max is the only new iPhone unveiled last month that is equipped with a Qualcomm cellular modem . The smaller iPhone 18 Pro and the iPhone Duo are equipped with Apple's C2 modem worldwide, as is the iPhone 18 Pro Max in all other countries. However, it is unclear if this is a contributing factor. AT&T said iPhone 18 Pro Max users who have experienced or continue to experience issues can return to an Apple or AT&T store for additional support. Yesterday, AT&T sent a text message to some customers advising them to update to iOS 27.0.1 immediately , even though that update does not appear to resolve the issues, according to comments shared by affected users. In an alleged internal email shared on Reddit today, AT&T clarified that its guidance about updating to iOS 27.0.1 is meant to help mitigate future impacts, but it is unclear if or how the update actually helps. Apple's release notes for iOS 27.0.1 only mentioned fixes for other bugs, including a Face ID issue affecting iPhone 18 Pro models. The alleged email added that customers can visit an Apple or AT&T store for a replacement device, but some customers said their request for a replacement under warranty was declined. With this issue becoming more widespread, hopefully Apple and AT&T are working to inform employees about the issue and implement a formal process. iPhone 18 Pro Max users should be aware that today is the final day to return the device to Apple under the company's standard 14-day return policy in the U.S., for customers who purchased or received it on September 18 launch day. Typically, Apple is able to address issues like these with software updates, so hopefully it will be able to fix the issue in iOS 27.0.2 or later. Hardware issues are more rare, but when they do happen, Apple sometimes launches a free repair program . We will continue to provide further updates on this topic as more information becomes available.
