An increasing number of iPhone 12 users report seeing persistent drops in 5G and LTE cellular coverage. Several users report the reception bars on their device suddenly dropping to zero and seeing a “no service” message on their iPhone 12, despite having network coverage and experiencing no connectivity issues on any other devices.
MacRumors reports there have been multiple reports of dropped 5G and LTE connectivity in various forums, including on Reddit, on Apple’s support forums, and on the MacRumors forums. Many users report seeing this happen when walking or in transit, while others report the issue while remaining stationary. The version of iOS being used on the device doesn’t appear to be a factor.
Several users say they’ve been in contact with the carrier or Apple technical support, and there have been suggestions that the issue may be rooted in the way that an iPhone 12 switches between cellular towers.
Reports indicate that the affected iPhones reportedly pass all Apple diagnostic tests, and that toggling AirPlane mode on and off fixes the reception issue for some users, but not for all.
The issue doesn’t seem to be restricted to one country, or to a specific cellular carrier. Customers using Verizon, T-Mobile, and AT&T all report the issue.
