iPhone 7 users are all of sudden are facing
issue with network as the iPhone started to say “No service”. The status
bar error message "No service" in iPhone is with a caution sign, and
it also says mobile data cannot be used until updated, but there is no update. The
issue was happening with iOS 11 so many of them updated to iOS 12 but still iPhone is giving No service
error with error pop up on screen like Cellular Update Failed” & “Mobile
Data Update Failed”. Only iPhone 7
users are reporting Cellular Update Failed in iOS 12.
While updating the iPhone to iOS 12, many
iPhone users faced network issue, just after iphone was updated using iTunes a
new error message appeared in the status bar - instead of just "no
service", there is also an exclamation point in a triangle. Also, if I go
into the settings, it says "error" next to "Cellular". The users check with their network provider
for any update for their iPhone but there are none pending. This is really
surprising as iPhone 7 network issue seems to originate from network issue but
no such things are acknowledged by network service providers. The same sim is active and is working
fine on the other phone but the issue lies with iPhone only.
The error reads "Mobile
Data Update Failed -Your iPhone cannot make and receive calls or access mobile
data until it has been updated".
Further it seems that users is also not able to restore the iPhone due to update
failure. While trying to reset the iPhone the user see a warning message-: You
will not be able to set up this phone after erasing. A mobile data update is
required before it can be activated again.
Many iPhone users tried reset network
settings, remove SIM card restart phone but none of these steps helped to fixed
the issue. Infact in some cases the network reset did help but did not last
long enough and the Cellular update failed started to happen again in iPhone 7.
How to fix Phone 7 "No
Service" Issues with Cellular/ Mobile Update Failed :
Apple have confirmed that small percentage of
iPhone 7 devices may show "No Service" in the status bar (even if
cellular coverage is available), due to a component that has failed on the main
