US Cellular HTC Desire converted to a GSM phone? - Desire General

Could someone answer a novice question for me? I'm kind of confused.
Can I get an (unlocked) HTC Desire originally from Alltel or US Cellular (CDMA) and convert it to a GSM phone (for T-mobile)? If so, is rooting required?
Thanks a lot.

No, different hardware.

You would have to find a suitable CDMA antenna, and even then it probably wouldn't work properly. Carrier is differentiated, for the most part, by the phones physical antenna. That's what dictates which carriers network the phone will work with.

Thanks. I think the CDMA version does not even have a SIM slot.

Gsm or cdma?

You can rest assured knowing you have GSM..
Your looking in the wrong forum i guess... You say 'GSM or CDMA Hero' (Hero is also a G2 Touch... ) don't flash either of those radio's you'll brick your phone.... I think
this is the forum for the G2/Desire Z (HTC Vision), not the G2 Touch.
the G2/Desire Z comes only in GSM versions afaik...
and just for future reference as you go along. Typical CDMA devices do not have a sim card (unless they are global roaming on GSM). GSM phones have a SIM card.
Thanks guys!

WCMDA is one of the air interface standards for UMTS (so simplistically, it signifies the 3G radio while GSM represents the 2G radio).
WCDMA is a completely different standard than CDMA (and actually competes with CDMA's 3G successor, CDMA2000).

CDMA vs GSM

Please talk here about GSM and CDMA:
What would you like to know? GSM phones have SIM cards, CDMA do not.

He doesn't need any advice, there are some guys flooding his rom thread with a fight about which is better, that's why he opened this one.
But thx anyway
Its pretty harsh really. From what info I've gathered the CDMA WFS is easy to S-Off, no XTC-Clip needed, but then harder to code custom ROMs for or something like that so they get less options. Brilliant idea by HTC[sarcasm].
It's like, they dangling a carrot in front of CDMA users but inside the carrot is super-aids! Not cool HTC, not cool at all!
Anyone know if there are any other advantages to the CDMA version other than you can S-Off without the Clip. Does not having a Sim-Card make any big difference? GSM/CDMA for battery life?
I have a cdma phone and I heard its slightly smaller than the gsm so we need smaller cases

What I've always wondered is - do CDMA owners have a choice before they buy? If so, why didn't they go for the GSM option?

No, Verizon and Sprint are only CDMA carriers. They do not offer a GSM service.

How pathetic. That explains a lot now. (I never knew why Sprint & Verizon & At&T had their own models).
Very good to know.

Yeah someone definitively needs to post a tutorial i will donate $10 for tutorial.
Head over to usgalaxys3.com. The owner of that site has already posted instructions to flash it to Cricket.
I'm in no way affiliated with that site, just sharing where I saw the instructions.

The radio hardware matters, it has to be compatible with 1900 mhz Sprint PCS band. But the other things like GPU don't matter. lol

Virgin uses Sprint towers so band is the same.

Bottomline - You cannot use GSM phone on a CDMA network unless it is a global phone and supports both GSM and CDMA as well as the frequencies of the carrier you intend to use.
That is an obvious spam post. Please people, there are no exceptions... you CANNOT take a Sprint or Verizon phone and unlock it to be used on ANY service that is GSM or uses a SIM card. Period. The unlock sites will just take your money. World band phones will already be unlocked for use on European GSM networks most of the time so no unlock code is needed overseas.

You can flash it to another carrier though.
Not if the carrier is GSM or uses a SIM card. There is no possibility. Whatsoever. And unless you know a network level technician on verizon, you are limited to the smaller regional carriers and prepaid services to flash a Sprint phone. And vice versa for a Verizon phone. They will not connect a phone that does not already have its ESN already in its system.

Its common knowledge about gsm and cdma,if you dont know what these are then you have no business flashing carriers.
Sprint phones can be flashed to almost all prepaid carriers,overseas cdma is less common however there are ways out there to even flash cdma phone to their carriers.My father in Ukraine had his Epic 4g flashed to a carrier that uses sim cards,so there are ways even overseas.I think some overseas carriers use both cdma and gsm.

Can you use an AT&T go phone sim in this phone?

Hi guys,
My friend bought an incredible 2 and paid to have it sim unlocked. He put his at&t go phone sim in it and it doesn't recognize the sim in gsm mode nor does it even register in global mode. I did a search on Google and got yes and no answers on whether this is possible. I figure no one would know better than an xda guy, so any help is appreciated.
Phone is also rooted and s-off if that matters/helps on the newest rooted ota.
Thanks in advance!

Technically speaking yes it should work but the phone will only be able to use the edge network due to limitations on the inc2 being built mainly for cdma network. I would try a different carriers SIM card to test. It is possible the unlock didn't work. I have seen a few people on here using the phone with tmobile which is almost the same network.

Dkstunna's cm9 has working gsm 3g if I remember right
So it is just a matter of flashing a rom that will support it? I see that a few roms say they support GSM. I read somewhere that verizon blocked the radio in the phone from getting AT&T signal, is that true and if so would I need to flash a different radio for it to work? Data does not matter, he mainly uses it for talk and text (why he got an incred 2 for just talk and text is beyond me)

Its not blocked, the phone just doesn't pick up the right band or frequency to get gsm 3g on certain networks, all the different type of data and voice use their own frequency range and our phone can't pick up the right band to get it, our radio is not made for it.

I have rooted and have mine s-off. Prior to doing this Verizon gave me the unlock code for GSM as I travel overseas. I am running aeroevan's cm9 on it and recently tried the local GSM providers SIM here in Wyoming (Union Cellular) in the phone. I switched the network to GSM and it picked up nothing at all. I have used this overseas with a Movistar SIM and have had voice and SMS. Some how I wonder if there is something built in that blocks GMS when the phone can receive a CDMA signal from Verizon.

I thought that by being a quad band gsm the dinc2 would get any gsm frequency.

Yes but not always the case. It most be one of these. Google is your friend
The handset is a dual-band EV-DO Rev A (850/1900MHz), quad-band EDGE (850/900/1800/1900MHz), and dual-band HSDPA (900/2100MHz) device

How to make One VX work worldwidely?

As the chip is Snapdragon 8930, which containes worldwide telecommunciation ability of using GSM / WCDMA / CDMA EV-DO(3G) / TD-SCDMA / LTE-TDD / LTE-FDD. How to make One VX able to use all of these bands?

The baseband is capable but a lot of features can be disable either by Qualcomm or HTC, hardware wise. Most likely, it is not possible. Besides, this model is exclusive to AT&T as far as I know.

It is "exclusive" to AT&T however it can be simunlocked pretty easily. Runs fine on T-Mobile 2G/3G.
I don't have T-Mobile 4G/LTE access in my area to know if it works fine on that band.

Yeah, I agree. But one of the big interests for smartphone hackers is to make the phone work or run beyond general-users' experience, like HTC HD, which can run Windows Mobile 6.5 / Windows Phone 7.X / Android / even Meego OS (Some OS may not stable, but it is fun). If One VX can work under all of the bands its chip supports, then I think it will be another amazing phone in future.

heyy, I have done bootloader unlock,s-off and root....how can I use my other carrier ship?? I put it in but requests pin..
someone help mee
there are some devices that have this kind of features blocked by software but most of them have a hardware restriction. phones like droid razr, htc rezound, samsung s3 verizon to name a few, have this restriction by software to work globaly (CDMA+GSM).
im not saying it can not be done, just unlikely (by software).
back when windows mobile 6 was still alive we saw a lot people with this kind of concerns. different models with the almost the same specifications. htc models with qwerty keyboard had tv out while non-qwerty ones had fm radio. others with the bands. this is even involves laws. the country i live the 700mhz spectrum is still being used for analog tv, hence, no other kind of devices can use that frequency.
again im not say it cannot be done at all, just unlikely.
my suggestion, search other forums of similar devices to see if anyone has tryed something like that.
