Cell phones: CDMA+GSM combination phone
CDMA+GSM combination phone
by ericthai - 9/9/04 7:19 AMHey guys
I just heard Verizon had came out with a new quad band phone that can do CDMA and GSM, its a Samsung A790. While in the US it will use Verizon's CDMA network while roaming outside it will be on Verizon's partner Vodafone's GSM network. Until now i have not heard of a phone that can do both GSM and CDMA. Does anyone know of any other phone that can do GSM and CDMA from Moto, Nokia, Sony? I am not a big fan of the usual tacky Verizon offering brands such as Samsung, LG, Kyocera or Audiovox!

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.

by FIL - 12/12/04 9:06 PM In reply to: Re: CDMA+GSM combination phone by ericthaiThanks for the info. I've been waiting for this combination of CDMA & GSM, in one unit, for a long time. Thing is I don't like Samsung Cell Phones. Having had two diffrent models. SCH N370 & SPH N400. Both models had FLAKEY software, although the phones look good physically. The A840, which I've never heard of until now, is a Motorola phone, and I've always liked Moitorola phones back to the Micro Tacf and the Star Tac.

CDMA and GSM
by birdmantd - 6/27/05 8:04 PM In reply to: CDMA+GSM combination phone by ericthaiI don't have any specific models or time frame, but I did verify with a local Verizon store that there will be at least one additional model coming soon. I also learned that the phone will switch to GSM domestically if no CDMA coverage is available.
CDMA and GSM
by dave1973 - 6/28/05 6:29 PM In reply to: CDMA and GSM by birdmantdIf 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.
Combo phone
by birdmantd - 6/28/05 9:02 PM In reply to: CDMA and GSM by dave1973I agree that the phone would rarely switch to GSM while in the United States. My only point is that in an area that has absolutely no CDMA or Analog coverage, the phone has a 3rd alternative (vs. no coverage at all). AT&T and Cingular had a similar phone that switched between GSM, Analog and TDMA but those phones are no longer available.
