Im living in Guyana, South America. I purchased this phone and had no problems. It is as it says: a factory unlocked phone so it works fine with my carrier. Just make sure to attached the bottom back on for signal since the antennae is in that part

Yo no recomiendo este teléfono. En Costa Rica funciono bien en GSM por 3 meses y luego falló la tarjeta madre. Conozco otros casos similares!

I don't know why not. I bought mine to use in costa rica and it worked great there. I now use this same phone as my cell phone here in the state of Washington where I live. I have a $.10/minute GOPHONE plan through AT&T;, which I am also well satisfied in. The AT&T; outlet store installed a new sims card and set the phone up with this plan. We go into Canada quite often and I think I could set this phone up there just like here by installing the 2nd sims card. This phone has a capability for two sims card. The one I have I would keep for here and the other for Canada. I think this is how the phone could be used. I know I could use it this way in Costa Rica. Hope this helps I don't know why not.
