Mobile Data Update Failed
Hi,
Have an iPhone 7 Model A1778 bought in Ireland with iOS 12.1 installed. Since installing this version when I turn on my phone I get an error 'Mobile Data Update Failed' and cannot get any service. The carrier settings are not possible to toggle, when I go into Carrier it tells me 'An update is required to use mobile data on this phone'.
I have tried:
Turn on/off
Turn on/off with sim card in/out
Reset network settings
Reset settings
I cannot reset to factory as it warns me I will be unable to activate it.
When I plug it into my macbook it will not sync with iTunes but it is connected as I can access the gallery thru 'Image Capture' app.
Can anyone advise how I can fix this as I really need my phone for work?
Thanks
iPhone 7, iOS 12.1
