i recently bought a unlocked US Samsung Phone off an inmate here. T mobile. He said he bought it new and unlocked. I figured unlocked would mean unlocked as in I could pop in my Bell or Rogers SIM card and it would work. But it doesn’t. I am going to assume I need to get it unlocked, again, to use on the Canadian networks. Bell specifically. I have gone on a few unlock sites and googled for some answers but I am a bit lost. I see on a unlock site there is a T mobile unlock app but I don’t think I would need that, the seller assured me that the phone was unlocked from t mobile. I am not calling bell because I don’t have the rest of the riding season to sit on hold and they will tell me no anyway, then try and up sell me a phone. Anybody have any experience with something like this and can pass on some advice.?
