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

I was wondering if I can have internet with Verizon since our phones have WCDMA but keep my GSM phone service with my sim? I am sick of this T Mobile internet things not working with outr HTC branded phones in south florida. Anyone?
Negative. The radio will not work CDMA. The chip is not provisioned for cdma. You would need the MSM7500.
Yes that, and the fact that GSM is different then CDMA. If the kaiser supported both but gsm was the main one then you could probably do that but it doesn't.
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...

i'm not for sure, but, i don't believe you will. if i recall, T-Mo USA uses the 1700/2100 bands. by the way, which HD model do you have: the T8282 or the T8285?
I have the T8282 model

so have you tried your phone with a T-Mo 3G sim? i recall reading that T-Mo must grant 3G access to 3G subscribers (certainly could have misinterpreted what i read). it's my understanding that both the T8285 and T8282 models have active 2100 bands. this being the case, you'd think one could at least get 3G service on the 2100 band.
No T-mobile 3g
Both models do not support USA 3g T-mobile.
OK Thanks, I was hoping someone on here cooked up somrthing to make it work.
Unfortunately not.
Query answered, thread closed
I have a Sprint touch pro 2, SIM unlocked by http://www.htc-unlocks.com/, to use on an AT&T USA carrier.
I don't know what kind of ROMs I can flash on it. Do I use a gsm ROM, a CDMA ROM, (I understand there is a difference, correct?)
It was a Sprint phone (CDMA), but I'm now using it on AT&T (gsm).
Could someone please list a few examples of ROMs I can flash on this phone?
thanks
CDMA ROMs, GSM won't work.
CDMA ROMs
Can you give me a link or 2 to some CDMA ROMs, I've looked and looked but can't find any!
thanks much!
go to ppcgeeks.com. that site mainly has cdma roms
Had a general question about the Sprint TP2. If unlocked, will it work on the 3G T-Mobile USA network??? According to PhoneScoop.com, it appears that the Sprint TP2 IS compatible with the WCDMA 2100 mode. Could anyone confirm this?
There's also a CDMA sub-forum for Rhodium here. But as has been said, go to ppcgeeks for CDMA ROMs.
Hello,
I was wondering if it was possible to convert Sprint HTC One to International or AT&T variant? All HTC One models are the same in terms of specifications i think so what prevents it from happening? They all are world phones and S-off is available to all the variants.
I'm just curious as I have a Sprint HTC One which I'm using on GSM network with a custom rom.
Thanks
If im not mistaken. The Sprint / Verizon HTC One are CDMA units and NOT GSM.
The LTE would work but you would have no voice communications.
Im not 100% sure how the hardware works in them when it comes to CDMA / GSM.
So im not sure you can flash a GSM radio and make it work like that..
Try it and let us know if it works.
I know for sure that when you flash GSM Rom on Sprint variant, it doesn't work at all so this has to go a bit deeper. Both Sprint and AT&T variant have GSM/CDMA/LTE on it i think.

Nope, there are several models of the One that HTC manufactures so they can optimize the antenna design for various regions/carriers.
The Sprint model can connect to the following frequencies (link):
2G/2.5G - GSM/GPRS/EDGE: 850/900/1800/1900 MHz
3G - UMTS/ HSPA: 1900/2100 MHz with HSPA+ up to 14.4 Mbps
3G - CDMA: 800/1900 MHz for Sprint
4G - LTE: Sprint: 1900 MHz

Since this is part of the physical design of the radio/antenna, it cannot be changed.

Unfortunately, the Sprint HTC One only connects to LTE on band 25. And according to the following list, Sprint is the only carrier using band 25, meaning the Sprint version of the One will only run on Sprint’s LTE network.
http://en.wikipedia.org/wiki/List_of_LTE_networks
EDIT:
There are ways to get the Sprint version of the One to run on AT&T and T-Mobile’s non-LTE GSM networks, but you need to follow the guides in the Sprint HTC One forum on how to SIM-unlock your device. Also, you have to make sure that AT&T or T-Mobile have one of the GSM frequencies listed above IN YOUR MARKET before trying to make the switch. In any case, you would be limited to 14.4 Mbps at best (assuming the market you're in has 1900/2100 MHz HSPA+).
Thanks!
This is the kind of explanation that I was looking for.
My phone is sim-unlocked already and works fine on 2G/3G networks in India. There is no 4G here so I can't be bothered.
