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.

Can I unlocked a thunderbolt and put my tmobile g2 sim and used it?
No. The TB doesn't use GSM as a radio and is strictly CDMA for the phone side of things. Also, the LTE radio is different than T-Mobile's 4G radio. I'm sure somebody with a more technical side of why will come in, but that's the basic reason it won't work.
the only carriers verizon phones can switch to is cricket and and sprint (if either carrier is even willing to activate the phone on the network).
T-mobile can only take unlocked GSM phones (which would mean att phones)
I don't know enough about the thunderbolt being used on different carriers cause I don't fully understand exactly what data is being stored on the sim card. If it is only 4g data than theoretically It should be able to work only on sprint/cricket (without 4g, if they are willing to activate it).

As above, no, you can't use it on T-Mobile, you could take it over to Cricket/MetroPCS. Metro I know uses 4G LTE, so you'd be able to get everything out of the phone. However, I know roaming with that provider sucks unless you don't travel anywhere.

MetroPCS uses a different frequency band for their 4G LTE (I think they're on 1700, and Verizon is on 700), so the LTE won't work.

No you cannot take it over to Cricket/MetroPCS. The phone does not have a traditional MEID to allow it to work on a traditional CDMA network, and the LTE radio is not compatible with the "LTE" system that MetroPCS runs.
GSM
If you don't know what you're talking about then don't post it. Obviously you don't have a Thunderbolt to say if it can be unlocked or not. HTC Thunderbolt uses GSM network on 4G LTE. It can be unlocked, but haven't figured it out yet.
NO CRICKET OR METROPCS can be run on it.
I took out my sim to see if the phone will work on 3G. And the result is no. No way of putting it on cricket.

LTE is not GSM. The Thunderbolt runs on 700 MHz LTE and 850/1900 CDMA. It does NOT support ANY GSM/UMTS/HSPA bands. You CANNOT take it to ANY GSM provider. If you were able to unlock it, you MIGHT be able to take it to another LTE carrier, but ONLY if that carrier also uses 700 MHz for LTE (for example, possibly AT&T once they launch LTE), but even then you'd be able to use it for data ONLY. It is unlikely that you'll be able to use it on another CDMA carrier either (such as Cricket or MetroPCS) because it isn't provisioned in the way all other CDMA phones are.
Jumping on the bandwagon, no.

The TB will NEVER work on any other carriers GSM network. Period. End Of Line. It is not a matter of "unlocking" the phones. The LTE standard does not define interoperability with existing the existing GSM standard. The TB cannot operate on a traditional CDMA network (think Cricket/MetroPCS) because it is missing fundamental components required in every CDMA handset (there is no hardware MEID on the TB). Without an MEID the device will not work on a CDMA network, no matter how much unlocking you try. It will not work because the network cannot talk to the phone and there is nothing you or anyone else can do to change that fact.
What VZW has done is create a hybrid system linking their LTE network with their CDMA network. There is a reason dialing *228 does nothing on the TB. There is nothing for the system to update. All of the settings are created on the LTE network and are pushed to the VZW CDMA network on their back end. Your phone number is tied to your SIM card on their network, not your MEID. Want to prove it to yourself, take the sim card out of your TB and put it in another TB. Care to guess what happens? I'll help. The new TB you just put your SIM card into will now have your cell phone number. Now if you have been with VZW for more then 5 seconds you would know that with every phone prior to change your number you had to call customer service and they had to update your MEID and in turn you had to update your phone (*228) so the CDMA system knew what phone belonged to what number.
Tl; dr...: LTE and GSM are not interchangeable terms and technologies. LTE radios cannot function on existing GSM networks. TB is not a true CDMA device and will not work on a traditional CDMA network.
I am always confused between CDMA and GSM...
Why a 4 band phone ,Evo 3d will not work in Europe?
BTW I am searching to buy one at Ebay. the search shows only Spirit branded phones. do they work in Europe (GSM)?
What is ESN clean or Bad ESN? Whats is the meaning of "unlocked" and if i buy a locked one can i unlock it by my self?
Thank You

I'm far from the expert so I'll give your questions my best shot and maybe somebody else with more experience on GSM can fill in some of the gaps.
bad/clean ESN only applies to CDMA. CDMA does not use a SIM card. once a CDMA phone has had its ESN marked as bad, it will not operate on that carrier. example, sprint (only CDMA network) evo 3d, the owner doesnt pay his bills, they mark the ESN as Bad for that device. if he sells the evo 3d, it can't be activated on sprint's cdma network. if you want to activate it on another CDMA network, like metropcs, it is doable, but sometimes considered a legally *gray* area.
"unlocked" in regards to the carrier of the device only applies to GSM type devices. on GSM type devices, once they has been "unlocked" they will operate on any GSM carrier.
i'm not about the band count, i.e. 4 band GSM. i would suggest looking at which frequencies are used in those bands and matching them up by frequencies and GSM/CDMA. as your profile is marked albania, i think most of europe uses GSM so CDMA will probably not be useful for you.
hope that helps some of the questions!
thank you... you were very clear.
still searching for the last question. If i buy a locked GSM phone, can i unlock it here by myself or i have to buy unlock code?
Well, doesn't all phones come unlocked in Europe anyway? Locking applies to GSM phones, and I've always thought only north American carriers do that. For example, if you, living in Europe, wanted the infuse 4G which is locked to ATT in America, you would need to unlock it to use it. Moreover, you must make sure the phone's frequencies match your carrier's. If I'm not mistaken, I think unlocking an Android phone is similar to rooting it. It's a different process all together, but its something you would do on your own.
Before Android tho, you simply need to call your carrier, tell them you're traveling overseas and you wanna use your phone there, and they'll give you the unlock code. Use some special commands to bring up the carrier unlock screen, input the unlock code, and bam, you're good to go.
I don't know if you still need an unlock code with Android phones, but if you want it, you would get it from the carrier of the phone.
You won't see any unlocking tutorials for the EVO 3d in the forums for the obvious reason that its cdma phone in America. But I'm sure once its released on Tmo-us, then there'll be a method.

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
Just wondering, because I have a Japanese model. I was originally quite fine with using GSM providers, however, now I've moved to a place where Verizon performs significantly better than AT&T and there aren't any other choices as far as I can see (MVNOs aside, but the problem I have with AT&T is with signal, and an MVNO isn't going to help with that). Now I want to switch to Verizon, and I'm wondering if the advice provided to the others with KDDI radios on Sprint Photons would also be the same for a plain old KDDI Photon.
verizon uses cdma and keeps a database of their cdma phones. Thus they dont allow phones on their network that arent already in their database (i.e. they wont allow non-verizon phones). Sprint is the same way.
The only caveat to this is roaming. They will allow non-verizon phones to roam their network as part of roaming agreements with other carriers. You just wont be able to use verizon as your carrier.
OK, then what of a Verizon MVNO, like Page Plus? That seems like it should be OK, from some of what I've read, as long as no one's blacklisted my phone's MEID (it's my first time bringing it to the US, so that shouldn't be an issue).

Page plus will take anything, sprint phones, verizon phones, any cdma phone for the most part that arent blacklisted. Might even take blacklisted sprint phones, just no blacklisted verizon phones.
Ooh, sounds good. In that case it seems like I just need to figure out how to flash in the right settings. All I remember is that someone else wrote in one of the KDDI radio threads that data doesn't work, but voice+text does.
