Purchased a Samsung Galaxy S6 refurbished unlocked phone, but the phone is not a true unlocked phone; it is a T-Mobile phone and is locked to T-Mobile. Canada computer would not exchange my phone or can supply any unlock key. I have tried to unlock this phone at a place in town that offers this service, but so far no luck - I was told the phone that I received was rooted and unlocked using software. Can not get an unlock code for it.
Generally, I like Canada Computers and find their products/prices good. Just never buy a phone from them.
