Technically, CDMA has a downward-compatible equivalent called R-UIM cards (ie, you can stick a R-UIM card into a GSM phone, and it looks just like a SIM, but you can't use a GSM SIM card in a R-UIM phone), but Sprint and Verizon have never sold a phone that used them (they sold phones without R-UIM sockets that had an equivalent circuit soldered directly to the circuit board). The closest any Sprint/Verizon phone came to having one was the HTC Apache... the Sprint/Verizon models were identical to the international CDMA models, except the R-UIM socket was never soldered on & the hole was left empty. As a result, lots of people in India bought American Apaches and soldered on their own R-UIM sockets so they could use them in India.
As far as how to tell the difference goes... if there's still any doubt in your mind... when making a call while driving, do you hear a loud "Clack" ever few minutes when the tower does a hand-off, and hear the signal quality vary radically from moment to moment? If yes, it's GSM. If no, it's probably CDMA (CDMA calls are handled by multiple towers at once, so the signal quality is less variable while moving in a car, and there's no such thing as a hand-off in the GSM sense, because there's no one single tower handling the call to begin with.
Technically, 3G GSM (UMTS) uses W-CDMA, which has the same advantages and operation as regular CDMA. However, unless you never use the phone outside of a 3G service area, chances are pretty good that it's going to fall back on old-fashioned GSM calls at least once in a while, in which case you'll hear the thunking and signal variation while moving.
Oh, I forgot test #2: does your phone make amplified speakers output a stuttering buzz? It's GSM. CDMA phones, and GSM phones operating exclusively in 3G mode, don't do that. GSM phones do. What you're really hearing is the carrier being turned off and on multiple times per second (GSM phones share bandwidth with 2 other phones by broadcasting data in short bursts in round-robin fasion, with each phone getting to transmit during every third timeslot.

Does the thunderbolt have any gsm bands? I know it has a sim card slot, so if i travel abroad can i put a different sim inside of it? And does it have any US bands? Thanks.

Here are the radio bands from the phone's specs:
Network technology:
CDMA: 800, 1900
LTE: 700
So, yes, and no. LTE is a GSM-type service, but as you can see the frequency bands are not the same as the current round of 3G phones out there (800, 1700, 1900, 2100).
Someday, when AT&T deploys their LTE network, if they're on 700 (no idea about that) you might get away with using their sim for data services (if the phone isn't sim locked or can be sim unlocked), but you're not going to get voice over AT&T. You could over Sprint, I believe, though.
Droid DNA work only with CDMA network or can be found with GSM module, I wont buy it but I can use only GSM network, please help I really want this phone?
You can set the phone to operate in CDMA or GSM depending on what protocol your local network uses. It is a global phone.
Hello guys!!! I buy used HTC EVO 3D, but when i open in my house, see this is CDMA version (no sim card).
I wana use this in WCDMA/3G with SIM card, but the phone dont have SIM slot
There any way to extract the information of SIM carrier(WCDMA) and input this information inside the CDMA phone?
Or any Hidden SIM slot in this phone?
Thanks very!!!
i alread buy at Ebay one USB SIM reader for get all information inside SIM, to try input on CDMA chip, but the radio still BIG problem.
Someone know if flash the GSM radio inside CDMA Evo 3D will work?
Otherwise i hear about Global phones can use both GSM/CDMA just with patch, so HTC EVO 3D is a global phone?
"If you have a Global Phone for CDMA Network and you want correctly use it on GSM Network than you have to edit the build.prop file to fully enable the GSM\UMTS and you have to set APNs to use 3g data"

If someone know, plz share with me
I live in Croatia. How can I most safely tell if my EVO 3D is CDMA or GSM? I'm asking this because I plan to put custom ROM on it so I must be sure.
Thanks in advance!
We have the GSM version in Europe, while the CDMA was prepared to US market. So most likely you have the GSM. But if you want to check it by yourself here is the trick.
There is a difference in trim colour around the cameras. GSM has gold trim, CDMA has red trim.
Oh! And the pins (for wire trick) are in different places:
- GSM: http://i3.bbs.fd.zol-img.com.cn/t_s...1C1ObyIeZA4AAEOD9nVh90AACmQwL5ZQkAAQ4n233.jpg
- CDMA: http://www.pocketables.com/images/old/6a00d83451c9ec69e2016305b34134970d-pi.png
Look for those tiny holes and if you find them you'll be sure.
