ok guys I feel that I'm asking the dumbest question of all but I do'nt know how to check if my phone is a CDMA devise or a GSM... Can anyone explane to me the basic differences in a couple ot brief sentenses...
go here http://www.wisegeek.com/what-is-the-difference-between-gsm-and-cdma.htm. this will explain it
Thank you I read a thread that said that CDMA don't have sim cards... GSMa do have Sim cards and that was the main differense.

Different technology in a number of ways. Most of these are not visible to the naked eye. CDMA doesn't use SIMs, but some CDMA devices also have a GSM radio so have a SIM for that. This doesn't apply to the Touch Pro (but probably will to the Touch Pro 2), but if you're not familiar with the device specs the presence or absence of a SIM slot alone won't tell you if it's a GSM device or not. There are other non-GSM technologies besides CDMA, too, so it can get a bit complicated. With a TP, though, checking for a SIM slot will answer your question about whether you have a CDMA unit or not.
If you currently have service, you can also tell by your carrier.

This new sub forum is dedicated to CDMA versions of HTC's Touch Pro.
Over the next day or so, myself and other Mods will be rooting through the Raphael ROM Development section and moving CDMA threads here.
Thanks
Thank You .......
wow awesome

thanks bro super thanks !!!
Hmmm... It might be a good thing to explain what a CDMA is.
(Yes, I am a bit unsure myself, though I do understand it has something to do with the frequencies that the cellphone will operate at?)
(Ah, I found it. CDMA != GSM, some extra version of the Raphael primarily meant for the North-American market, does not work in Europe... shame though)
Code Division Multiple Access) A method for transmitting simultaneous digital signals over a shared portion of the spectrum. Although used in various radio communications systems, the most widely known application of CDMA is for cellular systems that operate in the 800 MHz and 1.9 GHz PCS bands. As of 2008, there were more than 450 million CDMA cellphone users in the world, with more than half in Asia. Verizon and Sprint are CDMA carriers in the U.S., while TELUS uses CDMA in Canada. QUALCOMM is the developer of the CDMA air interface used in cellular systems.
Thanks A Million
Thank You, Thank You, Thank You for listening to US.

thanks for the new cdma forum..
Thanks!!! This is excellent!!!
thank you so much its a pain in the ass going though all the other posts to find cdma info
Hi,
How do I know if my phone/network supports CDMA? I am in South Africa and on Vodacom (now Vodafone) network.
Thanks in advance.

I believe that's GSM Network. Look here:
http://wiki.xda-developers.com/index.php?pagename=HTC_Raphael_WM6.1_ROMs
Ah I see... Ok... thought that maybe if I set the band to WCDMA and I get a signal it would be an indication that my handset/network supports it.
Thanks though!
Could the GMS Raphael specific forums be changed to a GSM prefix as this CDMA sub-forum?
That could start to minise confusion -- particularly those using searches and finding themselves to links posted in a Raphael forum but it's not the Raphael that they own.
...in other model forums it's rather easy to point out to one that they are posting in a forum that does not cover their phone. Not so easy when one reponds -- but I do have a Raphael/Touch Pro.
Sure, the GSM model was out first and is more widely available, but keeping the sole Raphael name for it is only going to invite confusion. Best to be pro-active now before forums become flustered with confusing threads and posts.
WCDMA & CDMA are not the same thing WCDMA is 3rd Generation data over wireless protocol used for GSM
CDMA uses EVDO Rev1 for data
IF you have sim Card, chances are u r on GSM CDMA doesnt use sim card (unless ofcourse you are on iDEN and i dont think there is a TP for nextel
gsm 3g is based on cdma so it is some times called wcdma... and cdma carriers can have sim card like chips called ruim cards i believe u would only find this in india tho.. and iden is iden its not cdma but sprint does offer phones that can do iden and cdma at the same time..
I would prefer a GSM phone over a CDMA phone anyday because of the SIM card

Every place else to do with the Raphael is assumed to be GSM.... Confusion is desired while all CDMA Raphael 800 discussion is ostracised to this section.
Yes, it would far more sense to actually title the Raphael ROM section as Raphael GSM ROM Development and similarly for this CDMA section.... Doesn't appear that it'll happen since the GSM model was released first and the powers that be here have declared it to be the sole deserving model of the unspecified Raphael name.

I prefer CDMA because when my phone gets stolen, the bastard cannot not use it anymore because the SN will be reported as stolen and the phone will be locked by my carrier.
Hi, i've maybe a stupid Q... does this phone support the sim card???
http://www.anumex.com/pictures/2557923-1.jpg
because I read that there are special cards to lte...
can someone guide me please.
thanks for taking the time to read
This phone takes a standard SIM card just like other AT&T phones. It's not an LTE device.
This phone uses SIM Cards only..
Sprint version is CDMA.
Oh! Thnx For your fast Answers...
i say that because i see someday a table that say somthing about a lte chip x.x!!
ok, i hope to be in this subforum soon!
hm,
the Elevate 4G LTE Mi-Fi at work has the same '4G' sim that HSPA+ phones have.

LTE SIMs (technically called a UICC) are designed to be backward compatible with 3G and 2.5G services.
If the qualdcom processor on the EVO is ment to support LTE which in turn uses a sim card shouldn't that make the phone a world phone I know it is suppose to have an embeded sim. But my true question is will we be able to reporgram the sim once we get root or will write have to go with more of a hardware mod if we wish to make it a world phone.

Sprint uses embedded LTE technology to my knowledge, so its not like on Verizon where there is an LTE sim card. Also, this phone is a CDMA phone, and therefore does not have a regular sim card slot (Like phones on ATT or TMo). No software modifications will change this, and I highly doubt that anyone could even attempt to make a hardware modification to make this phone a world phone. Also, and LTE sim card is not the same as a regular sim card, as they perform different actions (access to LTE and the rest of the network is seperate).
Yeah I was thinking that it does not have the slot the thing is that the processor does support gsm also I was kinda hopeing it was like the rezound it is cdma phone on Verizon. It was found out that just by removing verizons LTE sim card and adding a gsm one it allowed the phone to work as a gsm phone.
the evo lte does not have the GSM and HSPA+ radios to be a world phone
When I preordered, the rep told me it was a world phone. I didn't think she was right but I didn't say anything.
Yeah i read the same post on Engadget i think. What a bummer was hopping it was since it is rocking the same processor that the at&t one (correct me if im wrong). Plus like i also stated was hopping it was like the HTC rezound on Verizon that with a experiment it ended up working. O well .... still kinda wanna take it apart and try wouldn't be xda without some experimenting or moding.
My friend has a Droid bionic which wasn't supposed to have GSM support, but it did through some hacks on rootzwiki and using a T-Mobile sim card. I think that the s4 includes a GSM radio, so its probably possible at least if the sim card can be accessed. Lte is GSM based so it is likely that GSM support is there if software is modified like it was on the bionic.

Sure, you can use it anywhere in the world that has a compatible CDMA network.
Many identify world phone with GSM radios (which the Evo 4G LTE does not have), but CDMA (which it does have) does work well for roaming in Asia.
I've roamed with my Evo 4G across Japan, Korea, and China for both voice and data. There's a full list of countries with CDMA roaming on the Sprint website. As soon as you arrive in country (if roaming works), you receive a free text with the rates and instructions on how to make international calls.
Can you remove the Simlock from a CDMA Evo 3d so that it will be able to use any carrier? Telus or rogers etc... I have tried searching the forums and Google (that was a joke all of the results I could find were commercials for paying someone else to do it for you. I want to do it myself. If possible.
I do not believe you can flash your network over to a sim based network like rodgers due to the fact that cdma phones do not have the hardware integrated inside the phone to run gsm networks or sim based. Your best bet is to flash to another network like boost, virgin mobile, page plus or metro pcs. However any type of esn or meid cloning is illegal and is frowned upon when asking for help on xda. Asking for help will get into trouble here so google will have to hold your hand as you search it's massive data bases to find the method of flashing networks.

AFAIK, MSM8660 (which is inside CDMA 3D) can do both CDMA and GSM unlike MSM8260 (which is inside GSM 3D).... But I believe it's not possible to use GSM service on it, since it does not have a sim slot and a OS to support it. If Rogers have CDMA service too, then it should be possible.
Thanks for that little piece of info sir.

Correct, there is no SIM on the CDMA version. I read about someone a while ago that was able to hack the radio and get GSM to show up, but without a SIM card it is useless. If you could solder a SIM reader on and then hack the radio (which are extremely difficult) you may be able to do it, but it would not be worth it.

Should work with EVO 3D
You will have Sprint + Rogers/Any GSM carrier
Sorry for asking stupid question....
I did some research, but I still can't figure out why DNA can't uses other CDMA network.
Is it the problem if radio???
According what I see, DNA is able to unlock bootloader, s-off, root.
What stuff should I waiting for? Radio?
Your answer will help me know what kind of threads I should pay attention to. Thanks a LOT in advanced!
BTW, I am planning use DNA in Taiwan with a CDMA network provider.
I had checked the hardware is fitted to my network (CDMA2000 800Mhz). Thanks for all concerned!

Hi,
First of all, you must understand that GSM & CDMA are dissimilar technologies, whereas with GSM you can easily swap between carriers so long as they have the same/supported radio frequencies and your phone is sim-unlocked, this is not possible with CDMA. CDMA devices do not use a sim card to retain your account information or activation abilities. When it comes to CDMA (from my understanding) the ESN is key, the ESN must be added to your networks (for lack of a better term at the moment) ESN database. In the United States, most CDMA carriers will not add ESN's of other carriers phones to their network, your results may be different, because of your location. If your carrier were to allow or be willing to add the ESN of the DNA you obtain to their database than there is a possibility that it may work. (I am unsure if that can just be done or if it would have to be removed from Verizon's network & so forth, because I've never personally had to do such a thing)
There is a second problem though, the LTE radio / sim card interface. Because of the way these phones work on Verizon with LTE, I am unsure if you could even activate it, because it looks like the LTE sim is needed to authenticate your account to the carrier like a regular GSM phone. I have no idea how you would activate this phone without LTE / GSM on your carrier, even with the CDMA ESN added. It seems like it would be a double edged sword, but I could be wrong in this respect.
Also at this current time, this phone has root, and an unlocked bootloader through HTCDev, but is still **S-ON**.
Though none of those things have to do with you being able to use this phone on your carrier.
If your carrier was GSM I would say go for it because this is a GSM Global phone as well, but because its CDMA that you need I really incredibly doubt you'll be able to use this phone, but I may be wrong, but until someone else states otherwise I would look for a different phone.
Hope this Helps!
I am also interested in it. How can we check it out? I should go to my CDMA carrier and ask to activate my ESN?
Where can i find ESN? In Settings-About there is only MEID, IMEI, Phone serial number and IMSIAdded
I work for a CDMA carrier in the USA and with lte on the phones now, they truly act as gsm phones. If your CDMA carrier has lte then they can give you a sim and it will activate your DNA. However, if they only operate on 2g/3g then the post above me is correct with the ESN database and will USUALLY not activate the phone (in store sales reps usually don't even have the ability). Even if they have lte, activating another carrier's phone is not in the best interest of the sales Rep and they usually won't.
YMMV

I should mentions that we don't have LTE in Taiwan so far.
My carrier provides CDMA2000 1xEV-DO rev.B (I guess it is)
Is it operate as LTE OR 2G/3G you mentioned?

From my experience, they will not be able to activate it if they do not have lte, as they would need to have a settings file made for that phone to get it to work on their network. Nevers hurts to call and ask though.
