Is there an Android phone out there that works on CDMA and GSM networks. Are any of Verizons new motorola phones going to be world phones?
Maybe the best option is a Sprint Touch Pro 2 with an android ROM???

My company is still using the dying Nextel, and phone they issued is an ancient Motorola. I know Nextel is part of Sprint now. Does it mean I can use any sprint phone in Nextel network? I'm thinking to get an used Sprint Touch for this. Any suggestions? Thanks!
I don't live in USA, but if I recall right Sprint is a CDMA carrier, therefore you have a Vogue not an Elf, Nextel uses GSM phones (ELF) which is a different technology to CDMA making them incompatible.
My Nextel phone does have a SIM card. I put into a unlocked GSM world phone, but it doesn't seem to work.
Does CDMA phone also have a SIM card?
CDMA does not use SIM cards
I'm just curious if there's anyone out there with an HD2 on Verizon? If not, is it possible to do it? The HD2 is a quad band device, so doesn't it have the hardware capable to be on a CDMA network? I was thinking that if I bought an unlocked HD2, I would be able to put it on my account with Verizon. I guess I would have to be running a different radio in order to do that though.
Anyone have any thoughts, comments, suggestions? I really want one of these phones, but I can't switch from Verizon because no other provider gives me 3g in my area. Plus, my Touch Pro 2 is getting dated compared to that 1gz Snapdragon!
HD2 is a GSM phone. Pretty sure it can't be made to work on a CDMA network.
Technology
GSM: 850/900/1800/1900 MHz
WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
Taken from the HD2 tech specs on HTC's website.
If it has a CDMA radio, why couldn't it work if it were unlocked?
Does Verizon have a sim card to put in the phone? If not, how can they make it work on their network.
Verizon does have sim cards, they use them in the Blackberry Storm, which is both GSM/CDMA ...
But It may be like the storm if it is activated via the IMEI that it may not require a sim card ...
rly? i never thought verizon would use sim cards...can we bring non verizon phones them from lets say ATT to their network?
Verizon has SIM cards for their GSM/CDMA world phones. Sprint also has world edition blackberries with a SIM card. The SIM card is there so the phone is able to roam onto a GSM network outside of the USA. As far as I know this SIM card will not allow it to roam onto a USA GSM network, since there are no roaming agreements in place between VZ and ATT/TMO
The WCDMA on the HD2 is not the same as CDMA that VZ/Sprint use.
WCDMA is the 3G standard that GSM providers use. CDMA is well as far as i know the same old CDMA network that VZ/Sprint have used for ages with whatever "bolt on" enables 3G on their network. I dont follow the CDMA standard so i dont know all the specifics about the tech.
Edit:
I just did a small amount of wikipedia research. What Verizon/Sprint use is CDMA2000/EV-DO
http://en.wikipedia.org/wiki/CDMA2000
http://en.wikipedia.org/wiki/Evolution-Data_Optimized
This is not compatible with WCDMA,
Even though they both use "CDMA" family of technology http://en.wikipedia.org/wiki/Code_division_multiple_access
WCDMA is a wideband version http://en.wikipedia.org/wiki/WCDMA
Thanks for the replies guys. This is a bummer though. I was really hoping to be able to get an HD2 to use with Verizon. Oh well, guess I'll wait for the Droid X to release, even though I'd like to stick with WiMo.
Here's the deal. I'm spending the next 12 months in Canada. I want to buy a phone on the marketplace here and use it this year on a month to month deal with Canadian service. They are mostly GSM on the same bands as AT&T. When I return to the US next year I want to be able to use the same phone on sprint. How do I identify phones that work?
They will say "World Phone" or under the specs you will see GSM bands and CDMA bands. were on most CDMA phone you see "CDMA EVDO Rev A xx/xx/xxx/xxx/" only.
EDIT: You were faster typing eck0728
They are called world phones.
As far as I know Verizon and Sprint have HTC devices that has both, CDMA and a SIM card slot for GSM.
Check your preferred models.
What bands do AT&T/Canadian carriers phones use for full 3g?
Thanks gentleman.

Hi Guys, dose anyone have any idea if the samsung Epic 4G for sprint supports GSM networks??
as I know it's 4G phone for sprint, works on Wimax networks, and I heard that it's GSM capable as well, is that true?
Thx
I hope that's true... but I think It hasn't a sim slot
Isn't sprint a cdma Telco? Otherwise you'll be hearing ppl like me buying the epic and using it I'm aus. I would love a gsm sgs with kb

I'm pretty sure it's not. Sprint are CDMA (and their "4G" is WiMax). Their phones do not normally have any GSM capabilities.

No, it does not have GSM. It's CDMA only and specifically (at least currently) U.S. only.

Actually, the Epic 4G is CDMA/WCDMA capable. WCDMA being a hybrid of different GSM technologies. If you go into the Phone Info Test Mode (*#4636*1111#) > Phone Information, you can see how to change how the phone's radio interacts with different cell towers in the area. While in the US, there's no point in having WCDMA on because there are no WCDMA service providers here. However, when you go overseas... well, you get the picture.
The only reason this phone really isn't strictly GSM capable is because the radio isn't compatible, and there's no room for a SIM card to contain GSM network subscriber data.
"W-CDMA (Wideband Code Division Multiple Access), UMTS-FDD, UTRA-FDD, or IMT-2000 CDMA Direct Spread is an air interface standard found in 3G mobile telecommunications networks. It is the basis of Japan's NTT DoCoMo's FOMA service and the most-commonly used member of the UMTS family and sometimes used as a synonym for UMTS.[1] It utilizes the DS-CDMA channel access method and the FDD duplexing method to achieve higher speeds and support more users compared to most time division multiple access (TDMA) schemes used today.
While not an evolutionary upgrade on the airside, it uses the same core network as the 2G GSM networks deployed worldwide, allowing dual-mode operation along with GSM/EDGE; a feat it shares with other members of the UMTS family."

I was wondering if anyone could shed some light on this issue. Will the unlocked GSM T8686 Trophy work with verizon? Every google search seems to say that the Trophy is GSM + CDMA. I just want to know before I purchase this.
The Verizon version (HTC mwp6985) is both CDMA and GSM. The phone is capable of doing both, for roaming and international use. You would probably have to call Verizon to verify if they would alow the T8686.
The answer is NO.
Verizon require a special version of the HTC Trophy that's CDMA capable.
A regular HTC Trophy is GSM only.
Verizon's HTC Trophy is CDMA + GSM.
