I m frm gujarat & i hv a ques which google/xdA or my technoholic friends could not answer.After exhaustive research i couldnt make a decision....
question is: I have a friend in US who just bought an evo 3d frm ebay,but found it had bad ESN.Now he is going to sell it in 250$ coz he cant use it with sprint or any other carrier anymore. Can i use tht fone here in india on cdma or gsm networks,by unlocking or flashing it?I read tht its bootloader will be unlocked soon Plz tell me if this is possible anyhow...m goin to pay real money to him
Thanks in advance
It would depend on what type of towers you have ( cdma or gsm) you need cdma, and also what frequencies they are running. the US evo 3d runs on 1900 mhz. Also im not sure if you can flash the evo 3d yet. im sure its possible, but the methods and apps used to flash other phones havent been tested yet. probably best to wait it out for a while and see what happens

From what I understand, Evo 3D's are CDMA devices and are 99% worthless outside of the U.S. however, I did read an article stating that HTC listed the Evo 3D with quadband capabilities (GSM being one of them of course) the only problem is I'm not 100% sure if they did that because it really "is" quadband capable or if that just applies to international or special models. Maybe someone else will beat me to it and fully answer ur question. Your best bet is to try and find out if ur friends Evo 3D is quadband capable, if so, u might be able to use it in India by GSM. If it is only a CDMA device, its probably gna be worthless unless u want to be paying some pretty costly roaming charges

Im pretty sure that the EVO 3d is only dual band. the photon 4g is tri or quad band. The evo 3d doesnt have a sim card slot either so it doesnt have gsm capabilities.
thank u friends for ur quick replies...one of my friends was able to use evo 4g here,so i thought this also might work.Still i will wait for some solid answer B-)
thought there was gonna be a gsm version
Isn't the evo 3d gsm version releasing in france within 2 weeks?
(i might be wrong, just stating what i read)
Sorry, just read the post and no..., an evo 3d bought in the USA on sprint's cdma network by no means can be used on gsm networks...
Don't know whether it can be used on cdma networks in other countries, however i highly doubt it.
EVO 3D has both GSM and CDMA. I am getting the EVO 3d GSM from the US soon. I have checked on gsmarena which says that EVO 3D gsm is quadband.
I have sprint evo 3d working on reliance CDMA in india.
It cam with hboot 1.30/1.40 ( i didnt remember) but **** i upgraded the hboot to 1.50.
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.

In our area , there is available EVO3D cdma for cheap rate, it has a T-mobile logo on it, but the buyer says tht he has unlocked it for reliance cdma network
question is if i root it and put a custom rom on it, will it still be unlocked at reliance or it will be locked ??
if it has t-mo branding on it, it's probably gonna be the sensation, which is not the evo 3d. Secondly, t-mo is gsm only. If I were you, I'd verify if it really is the 3d, not the sensation, but I'm sure it will be the latter (if it isn't some scam to begin with)

I'm fairly certain my CDMA EVO 3D will NOT ever operate on a GSM network w/o changing the radio hardware inside.
Unless the GSM version comes with both radios inside, it will be impossible for it to operate on a CDMA network. "Unlocked" is generally a GSM term as GSM devices can be unlocked and then operate on any carrier.
Where as CDMA devices have to be programmed for a specific carrier. The programming process for a CDMA device can be a bit complex for people w/o computer experience.
Hope that helps clarify! I'm sure somebody else with more knowledge on the EUR versions of the GSM EVO 3Ds can chime in from their experience.

Also very great point! Don't think there is any GSM EVO 3D version being officially sold in the US under the TMO or ATT brand (the two largest GSM companies in the US). Perhaps a foreign GSM version of the EVO 3D, once "unlocked", could operate on a US GSM carrier such as TMO or ATT, but fairly confident TMO and ATT havent ever sold a GSM EVO 3D.
As a double check, if you wanted, a quick glance at the line up of phones available on their web site should help clarify. Or if you really wanted, call their customer service departments and ask about a EVO 3D or any type of 3D device to see what they have to offer.
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.
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.
