Where do GSM phones work?
In many countries around the world, but support in the USA is quite bad from what I hear, and although Rogers claims to cover all of Canada, that is hardly the case. You will find that when you travel in the countryside, reception is often non-existent, especially out West where I live. GSM and CDMA technologies are totally incompatible even if they transmit in the same band. The encoding of the information is different, so a GSM phone cannot talk to a CDMA network. Q: Can you take a GSM phone travelling? A: Depends if you have what is called a triple frequency phone. You see, while Europe and Asia work on the 900/1800 MHz GSM band, for some reason or other North America decided to use the 1900 MHz GSM band. I am sure there is some dumb bureaucratic reason for it. In any case, there are some phones that support all of those bands, so those are the ones that will work all over the world, provided that GSM service is available in that area. On the V66 I had to switch frequencies manually
