How do I know if my iPhone is unlocked?
Just yesterday, I purchased a pre-owned iPhone 6. The original carrier was Verizon, but it also worked with my Cricket micro-sim card. So I guess my real question is, if it works with lets say two service providers that aren't joint per say (ex. Cricket/AT&T), is it also unlocked to leading providers like T-Mobile and Sprint? I'm not sure if I explained it right, but I hope I'm making enough sense.
Questa è una buona domanda?
