How to determine whether my T-Mobile Note 3 is region-locked w/o a foreign SIM?
I purchased a carrier sim-unlocked T-Mobile Note 3 (N900T) last night and I need to determine whether it is region-locked or not before sending it to my sister in Hong Kong. I don't have the T-Mobile SIM card, and is unsure whether the phone was first activated with T-Mobile before it was sold to me.
I was told that if the phone was not activated with T-Mobile then the phone stays region locked. If that is the case, Chainfire's RegionLock Away wouldn't help, would it?
What are my options?
