Cell phones forum: CDMA+GSM combination phone

I heard about it too. These phones are supposed to be for world travelers, where it'll use CDMA in the USA, but in other countries, especially in Europe, use GSM. But I wonder if these phones will be used to eliminate analog by allowing roaming when the phone can't detect a CDMA signal.

Sprint, US Cellular, Cricket, and Alltel are ones that come to my mind that use CDMA.
T-Mobile, Cingular, AT&T (will be Cingular at the end of the year), Einstein, and Centennial Wireless use GSM, and Centennial just started using GSM.
Nextel is supposed to come out with a phone that will also have GSM in it too, besides their proprietary digital standard, IDEN.

i saw the specs on the manual of the nokia 6630 and it has global roaming with WCDMA and EGSM 900/1800/1900 networks. i still wonder though if i need the fourth band (850 frequency that is) as it seems its only for the US (in order to get wider coverage). my main conern is in japan and korea. i get no signal there with my tri-band that has no CDMA. with the nokia 6630 they say i can. i still have to find a quad band with CDMA though. anyone know?

If that phone automatically switches to GSM when no CDMA coverage is available, then people can expect roaming charges as Verizon Wireless only has roaming agreements with select CDMA carriers, mainly US Cellular & Alltel, which come off the top of my head. I don't think Verizon & Sprint have roaming agreements as when I traveled into sw Michigan around Benton Harbor & Niles, Sprint has coverage around there, but Alltel picks up any calls I get. But back to the subject, I believe the other phone that'll come out will rarely switch to GSM as there's more CDMA coverage in the USA than with GSM. The old Voicestream brought GSM to the USA, but it took AT&T & Cingular to switch and try to build up their networks based on GSM.

I have been using the HTC TouchPro II for a year now. It operates on my Sprint CDMA network when I'm in the USA, and I use it in GSM mode with its own (different) phone number on the BTL network when in Belize.
