Does anyone know a specific phone that the bought unlocked and have used successfully on the telus network by buying a sim card and then using prepaid cards? I know that all phones that are HSPA 850mhz or 1900mhz are supposed to be compatible but Im afraid that I will spend 300+$ and then it wont even work with telus, all other service providers where I live are awful . Any help can someone reassure me that all HSPA 3G 850 or 1900 phones will for sure work? ALso why is it that some of the phones that telus carries right now e.g HTC Heroâ„¢, when I looked up the unlocked version just to see it says that they run on 3G : 900 and 2100 what does this mean. Do different phones that are technically the same phone run on different networks? I am really confused. Can any one help me out in anyway?
