Can someone please confirm for me: Does the Samsung Galaxy S i9000 work on a CDMA band with 3G? I see six of one half dozen of another answers for this.
Please and thank you.

The I9000 is a GSM/HSDPA phone. It will NOT work on a CDMA network such as Sprint or Verizon in the US.
I believe your confusion is the difference between WCDMA and CDMA.
WCDMA is HSDPA. It is NOT CDMA, but a 3.5G sort of. It is a newer/different technology than CDMA.
CDMA uses a hardcoded ESN for connecting to the network.
WCDMA uses a SIM card for connecting to a network, making it much more similar to GSM than CDMA.
I hope this helps a bit.
the only 2 known model of actual CDMA bands for the Galaxy S is the Edge 4G version and the other version from China
Yes it answered my question. Thanks so much, both of you

Greetings guys I just like to know if its possible to Get a CDMA phoe to be converted to GSM. let say I want to buy a HTC diamond from sprint which is a CDMA but i know theres a slot inside for a SIM card now can I flash it to make it a GSM compatible phone? thank you for the answers.

No, there is no slot for a sim card in my CDMA Diamond. The radios in the CDMA and GSM phones are very different. There is no way the radios will work.

Oh I see thank you for that information I just figgured because my GSM diamond has that option for WCDMA thats why I think the Diamond works both ways.

Common mistake, WCDMA and CDMA are completely different things. WCDMA is UMTS, high speed 3G for GSM phones. CDMA is its own type of network separate from GSM, using no SIM cards. Many people mix them up, but just make sure to note the difference. ;-)

Has EDGE, not EVDO, this is a GSM Diamond, plus the numbers are 3700, that is also a telltale sign.
That's a standard UMTS/WCDMA + GSM version.
But for AT&T, you will only get GSM coverage. The UMTS/WCDMA 3G on that phone runs on 900/2100mhz, whereas AT&T uses 850/1900mhz for its 3G.
If you want to have 3G right away, you should go pick one up from BestBuy which is selling the 3G 850/1900mhz version. Of course if you don't want 3G (or don't want to pay AT&T for a 3G plan) then it won't matter.
As you can see on the web site theres 2 version of HTC diamond one is 3 band and one is 4 band is there any significant difference? because currently I bought the Quad band from that web site Im kinda confused because for some reason theres many version of this phone.... and one more thing the 3G for AT&T is that the one they call the Media Net because I added that to my service which will start on the end of this month I just want to know before i spend money on something that wouldnt work on my phone thank you once again for the knoledgeable people here...
Which is the t-mobile version? Cdma or gsm?
There are two android development forums. I am not sure which one i should download rom from and whats for the us t-mobile version.
I don't want to brick my tab by going to the incorrect forum for a rom.
Kindly let me know.
Cheers.
Assuming you're only interested in US networks, TMo and AT&T are GSM, and Verizon and Sprint are CDMA. Outside the US, it is almost all GSM.

Dave

Hi everyone i tried searching but didn't come up with anything. I'm considering purchasing an unlocked nexus one on amazon and I'm not sure if its a tmobile or att version I have tmobile as my provider if i were to get an att version would i still get 3g access? I know if it was the opposite i there would be no access for 3g on att.
Thanks
I believe t-mobile's 3g is 2100mhz, which means the atnt one should work on the network.
I'd get a second opinion though, I'm more knowledgeable on Australian networks than US ones.
Ok thank you for the input, if anyone could confirm this that would b great.
The devices are completely independent of one another in regards to 3G. Cross network compatability only extends to Edge services.
Someone jump in and correct me if I am wrong, but I believe that T-Mobile 3G requires both the 1900 and 2100 frequencies to work (up & down link).
Rod3 is correct the at&t version will not work on t-mo and the t-mo version will not work on at&t, in respect to the 3G that is you will still get edge either way.
Although as far as the both 1900MHz and 2100MHz I'm not sure about that but it's possible, anyone care to add some info.
EDIT: Just Googled it and it's 1900MHz for 2G and 1700MHz/2100MHz for 3G encase anyone is interested.
Dude, thanks for the correction. I knew there were 2 frequencies for 3G and I just picked one off the top of my head. Now that I think about it, yeah 850 and 1900 were for 2G.
Hey everyone. So i have a question that i can't find on here so im going to ask it. I have a Verizon HTC one unlocked. The sim car works fine and i can do everything on the phone with the T-mobile sim card. The issue is its always Edge data. Is there a specfic APN i have to use? something im not seeing? Does anyone else have this issue? It is a stock factory HTC One, nothing custom.

I don't think the Verizon model will have the correct radio frequencies to use T-Mo's LTE or HSPA+ network, hence you're stuck on Edge. If you're staying with T-Mo, I'd suggest selling your current One and buying a T-Mo specific HTC One.

This is pulled from Verizons website
Network: LTE, CDMA/1xEVDO Rev. A (800/1900 MHz)
Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(1900/2100) aGPS capable for E911 emergency location, aGPS (assisted), sGPS (simultaneous), Standalone GPS, eCompass, GLONASS
T-mobile uses the 1900 Mhz base band and the HSPA as well. So i don't see the issue in that one.

From what I can tell, nobody uses the dual 1900/2100 to achieve 4G like TMO. The UMTS referred to on that phone is for worldwide use, not US. So while it may have the frequencies, it is not set up to use them like TMO. Your software and firmware are set up to work with Verizon and overseas, not with a competitor like TMO. TMO refers to theirs as HSPA+. However, it might work on the new "reframed" 1900 bands (which is called HSPA), but those are not very highly deployed. Unfortunately, I don't see LTE on that list of frequencies. The TMO LTE is really great. EDIT: I mean TMO LTE, which is also 1700/2100.
I suppose you could try unlocking it and flashing the TMO radio, but there is an entire thread on trying to unlock TMO frequencies (in that case on the developer version), and no one has figured it out yet.
I concur that your best bet would be to sell the phone and get a TMO model.

Yeah thats what im thinking. I need to contact and t-mobile rep and see if the re-farmed LTE here. Ill call and ask.
Alright so i called the rep and he said the area i am has been re-farmed to the 1900 range and i should be getting at least HSPA/3G but im not. Very odd issue

Verison use the CDMA, maybe that's why you can only use 2.5G network, just like some phones in China, they only have GSM in common

yes but this phone has 4g lte already in it which accepts the sim card. Also, i have seen other verizon htc ones with t-mobile and never had a issue. I fell i may have to use a custom rom.

What he is referring to is that what Verizon uses as "3G" is CDMA technology. So although they (T-Mobile and Verizon) may be on the same frequency they're using totally different technologies. Just because it has a sim card slot for a Verizon sim doesn't mean the device will be compatible with another carrier's sim. A custom ROM would not resolve this issue. Your best bet would be to sell this device and purchase one from T-Mobile. :fingers-crossed:

My understanding is that the devices run on different systems for 3G and different LTE bands. You wont get more than GSM compatibility (GPRS, EDGE). Hopefully it is something that a software hack can fix but if you read around all the HTC One forums you will see no one has found it. Right now it is not possible.

My question is that HTC makes phones for all T mobile verison sprint the same, so I believe its just software problem that we cant use Tmobile 4g lte on Verizon unlocked phone. SO does anyone have any comment for that?

It is hardware not software that is the issue. The T-Mobile variant has different bands than the other variants including Verizon. T-Mobile is a GSM variant while Verizon is a CDMA variant. Here is a comparison of the specs for the variants.
CDMA and GSM technology requires the antenna to be done differently. If they are not programmed to use those signals. Nothing you can dox will change it short of putting a new antenna in.

Because you can only unlock GSM. Cdma uses the serial/esn number of the device.
Has there been any update on this? I called tmobile and they said it was simply because I couldn't put in the APN. So, there's no chance that rooting the phone and putting a tmobile rom on it would fix the problem and let me get more than edge speeds.
I myself have been wondering the answer to this. The device might seem the same but under the cover they are different. The actual daughter board which the camera, vibrating thing, volume rocker, power button are connected to are fairly different from each other. The CDMA variant is not compatible with the GSM variant. Not even by adding a CDMA daughter board to the GSM motherboard and vice versa, the are made quiet differently and will not be able to use GSM bands on a CDMA m7

1. Enable USB Debugging before flashing custom recovery.
2. Make a backup via recovery before granting apk's root permission, editing system files, or flashing a new Rom

Hello.
I live in a counntry with both GSM and 4G LTE networks. Reading this thread: http://forum.xda-developers.com/desire-510/help/virgin-mobile-htc-desire-510-gsm-t2965839 for the efforts of unblocking GSM bands thre is something I don't understand. If I buy the Sprint version of the phone, it is posible for me to use it outside USA with a 4G LTE capable SIM without having to unblock GSM Bands? Or do I need to have CDMA support in my country to be able to use the phone?
Thanks.
You would need a CDMA network; it's not working on GSM networks!

The thing is, where I live, people are selling this phone very cheap (less than half the price) becasuse isn't posible to unlock it on gsm at the moment.
Did it work for you ?
Did it work for you ? cause I have the exactly the same problem with my device and I don't even know what to do till now
