This is why iOS and overall firmware updates exist.
A number of users have reported that their iPhone 12 units have been reporting persistent drops in cellular coverage. The reports have surfaced on Reddit, Apple’s support forums, and the MacRumors forums, wherein some users have described suffering issues when walking or in transit and some seeing the same problem when stationary.
Some users have reported suddenly losing all reception bars and seeing a “no service” message on their handset, in spite of being in an area of network coverage and seeing no connectivity issues with any of their other devices. The iOS version installed on the iPhone 12 doesn’t seem to present a factor with the issue.
Several users who contacted Apple technical support or their wireless provider have indicated that the issue may be related to how the iPhone 12 switches between cellular towers. Affected iPhones reportedly pass all of Apple’s diagnostic tests, while toggling Airplane mode on and off seems to correct the lost signal reception for some, but not all users.
Users have reported issues with the iPhone 12 with wireless operators such as Verizon, AT&T, and T-Mobile. Representatives from Verizon have stated that the company is aware of the issue.
