When Your iPhone Has no Service, Do These 9 Steps

Are you unable to make or receive calls? Can't send messages or use your mobile data? Do you see the 'No Service' message at the top of your iPhone screen? That means your device can't find a cellular signal to connect to.

What to Do if Your iPhone Has No Service?

There are a few reasons why you might've encountered this problem. The most obvious one is if you're in a rural area near a forest or further away from the city where there's no possibility to get service as there's no signal. Other reasons can be an enabled Airplane Mode or an issue with your iPhone settings. Or maybe a minor bug.

Another reason can be a bigger software bug. Unfortunately, you won't be able to fix it yourself. Usually, Apple recognizes these bugs fast and releases a software update to eliminate the bug.
