The "No Service" message is a downer for any iPhone user as it makes them unable to operate their phone for its basic functionality like a call or a message. You expect it to go away but there are times when this issue stays, and you start to panicking over the possible problems and diagnosis. Sometimes the problem causes the battery to die, and it may worsen with time. We try our best in this article, to list out all the things that you can try with your phone before start contacting the SIM or iPhone people.
Connect device to computer using lightning cable.
Check your cellular data settings properly, and make sure there are no errors present in those modules.
Before anything, make sure you are in a area with proper network coverage.
Then go to Settings>Cellular> Cellular Data, and make sure that Cellular Data is set to ON.
Set the Data Roaming option to ON as well, as that is a possible fix for few operators which can be found under Settings>Cellular>Data Roaming.
Go to Settings>Carriers> Turn OFF Auto Carrier selection. This will turn off the Automatic Network/Carrier Selection as sometimes continuous change between the possible network operators may lead to development of the issue in the phone.
Go back to home screen to check if network is available now. This might have been caused due to the area you are in being out of coverage for that particular voice/signal settings.
Handy even outside the actual airplane, you can use this function to apply a refresh in your network settings and start the SIM services from the scratch again. Try keeping it off for sometime and then turning it on.
Switch 'ON' the Airplane mode.
Keep it 'ON' for about 60 seconds.
Alternatively, swipe up in your screen and access the iPhone Control Centre. At the top left, find the Airplane Mode, and turn it ON and then OFF after a minute's time.
You should try resetting your whole network settings under Settings>General>Reset> Reset Network Settings. You'll have to re-enter all your details like passwords and other initials for all the settings like WiFi, cellular data, VPS, and APN after the reset is done. Hopefully, this reset fixes your issues.
Go to Settings>General>Click on Reset> Reset all settings> Enter PassCode> Confirm, this will reset all your settings to the way in which it came. All your data will be lost, so make sure that you have them backed up.
Put the SIM back in the tray and close it.
Note- You can further confirm on the SIM card's functionality by testing it in a different phone. If by chance your SIM is not working or if you have noticed damage on it, you should contact your service provider for a replacement of the same.
While the same issue may show up for an Android phone too, the settings or interface of the iPhone might not be known to the new or inexperienced users. We hope that this article helps you in fixing the annoying 'No Service' before you hit the Apple Store looking for a replacement over your current iPhone.
