Hi, this seems to be the same issue as a lady called Freda had but I haven’t found a solution.
iphone 7plus on iOS 11.4.1
Showing Orange F 3G
Getting “you are not subscribed to a mobile data service”
Have tried all the usual advice like resetting network etc
30 mins call to 7777 repeatedly telling me to go to mobile data account but this option does not exist
Therefore cannot manually set APN
No option to remove Profiles either
Was told to go to Apple but this is a carrier issue
If I had any hair left I’d be tearing it out.
Please help ASAP!!
