Alski, thanks for the glossary information. Now I understand these 'bands' things very well after doing the readings. Before I didn't pay too much attention to these concepts. In fact, to my big surprise I have been using a PCS (i.e. 1900 Mhz) GSM phone for a few months and I don't even know about it until tonight. My provider is called Microcell: microcell.com Now everything is very clear. Last month, I have a relative from HK and he took over a Motorola 'tri-band' phone and without any adjustments, voila! it works in Canada. The phone automatically searched for a provider in Canada (that has a roaming agreement with his home provider which in his case in ChinaUnicom) and it tells you the network is ok. When travelling across China and HK, 'dual-mode' phones will be good enough. But for people who wants to use the same GSM phone in China, HK and North America, then you need a 'tri-band' phone. But the trick is that your home GSM carrier needs to have roaming agreement with a North American GSM carrier in the area you happen to be travelling to. My brother who came at the same time from Beijing using exactely the same model of Motorola 'tri-band' phone didn't have the same luck. His 'tri-band' phone didn't work in Canada since (I think) his particular home provider doesn't have an agreement with a Canadian local carrier. According to my relative, Motorola is the only maker of 'tri-band' phones : motorola.com mot.com So in Palm case, the Palm/Realvision phone is 'dual-band', that means they will have no problem roaming in China and HK but it won't work in North America. I used to find these very confusing but now it's all quite simple and clear. Mang
