iPhone 6 Carrier settings gone, constantly searching.
Hey all, I hope someone can actually help me with my question as this has been an on going issue for weeks now.
I first noticed my iphone 6, 11.4 iOS, was searching for my network and tried to fix it by visiting the discussion page and looking at solutions, however my carrier settings disappeared so I google'd more solutions, I have done everything suggested to me, I have reset and backed up, factory reset, reset my network settings, checked the sim with the carrier etc and everything is fine and working. I even recently sent the phone away to be repaired back to Amazon and it has came back, it worked briefly actually with the carrier settings returned and network connection HOWEVER when I restored my photos/apps/settings etc from iTunes onto the phone the problem came back, the searching in the top left continues and the carrier setting has disappeared again.
I get a wifi connection, and a 'Three WIFI Call' Network on it, in mobile data > carrier services > i can see the carrier services which allow me to contact Three, my network but there is no 'carrier' settings in the settings homepage.
At this stage I am fed up, I have done everything apple has suggested and spent a lot of money trying to get this issue fixed. PLEASE If anyone has any further suggestions or ideas let me know.
Thanks,
-Jac
