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.

Anytime, I almost bought one for telus and it wouldn't even work on Sprint, they are both CDMA.

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...
Could I flash a telus diamond with a rogers rom to use with rogers sim? Will it work?
thanks
Mike
No, you'll need to SIM unlock the device.
No.
The Telus Diamond is CDMA, so it doesn't use a SIM. Also, the Rogers GSM ROM won't play nice with the Telus hardware and you'll end up with a really pretty paperweight.
It's possible, though not exactly easy, to transfer from one carrier to another as long as they are on the same standard. As an example, you could go from Telus to Bell or from Rogers to Fido, but not from one standard to the other.
Even if you're going between two carriers that are on the same standard, make sure that they have the same radio bands, as they differ from one geographic region to another. What that means is that is you buy a GSM Diamond from Europe, chances are that it won't have all the neccessary radio bands to access Roger's 3G network here in North America, so you'll be stuck rocking EDGE only.
Good luck, and I hope you find this helpful!

I am new to my Diamond phone and would like to know the difference between CDMA and GSM phones. How do know the mobile is CDMA or GSM?

There are loads of sites available through google (http://www.google.com/search?q=diff...-ca&ie=UTF-8&oe=UTF-8&startIndex=&startPage=1) which details the difference between the CDMA and GSM cell phone network technologies.
Seeing as you're from Canada basically Bell & Telus = CDMA. Rogers = GSM
Thank you Rumball
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:

I know what the best way to go is but i am very curious as to what is really keeping it from going out of edge. baseband? Is the TMO and Verizon radios the same? these are things i need to know! >.<

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 have a T-mobile HTC ONE M7, I'm planing to switch to Verizon, Will I be able to get LTE/4G?
Is my Tmo M7 supported at all by Verizon? What network will I be able to connect to?
Is there any way to make my phone support all or some of Verizon's bands? A ROM or a Radio!! Maybe something else!!
I have tried to find this info, but I couldn't. The only thing I found is that both T-mobile and Verizon use the 1900 band for LTE!!
Please if you know anything about this let me know
Thank you

T-Mobile is a GSM phone which doesn't have any CDMA bands, so you will surely limit yourself on their network. Also, T-Mobile and Verizon have different partition tables so the firmware and roms are not compatible. If you know someone on the Verizon network, ask them if you could use their SIM card to see what type of service you get with the TMO phone. Here is comparison chart of the various HTC One's, check out the Secondary Cellular Phone.

Like said above, TMO htc one use GSM bands and Verizon use CDMA bands. Your phone also need a MEID # (the equivalent of the EMEI for CDMA network) which you don't have on a GSM HTC One (manufacturer-assigned). And afaik, Verizon will not accept non-verizon phone on their network. Your best choice if you want to quit TMO is to choose another GSM carrier (AT&T for example). Your phone also must be sim-unlocked to change carrier.

Thanks guys for the replies, I thought there might be some way to change bands :cyclops: I'm not an expert lol
Looks like I will be switching to ATT
