I have no issue with my phone. I just found this “glitch” with one of them In my iPhone 6 the carrier is not showing on the status bar, but on my wife it shows. Doesn’t affect functionality. Both on same iOS Both tested same SIM Both restored via iTunes I like when the carrier is not showing, how can i replicate this?
No carrier
Carrier showing
Have you tried Uhelios? http://uhelios.com/downloads You can change the carrier logo to anything you want now (no Jailbreak required).
