My friend just got her iPhone 6, Verizon model. She put her T-Mobile sim card inside of it and it's giving her "No Service" on the top. What I've tried so far 1.) Update Network Settings (But no updates were there to be made) 2.) Reset Network Settings Didn't do anything. Any idea what's going on? Verizon models are completely unlocked, so I have no idea why it's having trouble getting service from T-Mobile.
