Tmobile iPhone 7 Plus purchased outright from Apple store unlocked or not ?
Hello everyone,
I recently purchased the iPhone 7 Plus outright through Apple online store. I just wonder whether or not my iPhone is unlocked. I tries to put an Apple sim card (came with the iPhone) in the phone and it shows "invalid sim card".
So, is my phone locked to Tmobile ?
Please help me.
Thank you.
iPhone 7 Plus, iOS 10.0.2
