Mobile data error - after iOS 18 update - modem firmware 2.15.01
Hi everyone, I recently updated my iPhone to iOS 18 and have been experiencing significant issues with my cellular network since then. The primary problems include: Random disconnections from the cellular network Frequent "call failed" errors during phone calls After some troubleshooting, I identified that these issues are related to the modem firmware. In an attempt to resolve this, I downgraded my iPhone to iOS 17.6, but the modem firmware remained unchanged and the problems persisted. Today, I updated to iOS 18.1, hoping it might address the issue, but unfortunately, it didn't help either. Has anyone else experienced similar problems? Any suggestions on how to resolve this issue or if there is an expected update to fix this modem firmware problem? Thanks in advance for any help or advice! IPhone 15 pro, iOS 18.1
