I'm kinda newbie with this Cell/PDA thing, and wonder if someone could help me ?
I've bought Treo 180 that was activated with VoiceStream (T-mobile) , and I've put FIDO (Microcell Canada) SIM Card in it, and I'm able to dial out, and receive calls, so I suppose phone was unlocked, right ?

Problem is that on the top of the screen I have message saying: "Fido, Roaming" !!!

Does anyone knows why this happens ? Does phone really roams, or it's just some kind of network lock ? Does anyone knows how to get rid of it ?
