A rep at spring I was talking to was talking to new about some cool stuff, he mentioned u could use it off of an att 4g signal? can I get more info on this?
Well, I the photon does not have hspa+, or LTE, and so no. I Unless the photon has hidden hardware than I would have to say solidly no. I Unless there's a gsm unlock than you really can't use att, right now

As of right now there is no domestic GSM unlock for the radio. Sadly.
But its at least possible on our phones? I know its not on most cdma's
IF someone unlocked the GSM domestic radio block, yes, it would be possible, as our phone supports both GSM and CDMA radios, but as it's locked, and I haven't seen really any progress on it (as I'm sure it's a total pain in the ass) I don't think it'll happen to be honest.

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 own an HTC Thunderbolt, but I am forced to switch to AT&T. I am able to buy an unlock code for my phone, will I be able to unlock it and it run on AT&T? I would like it to run 3G or better. If you have any info, please let me know. THANKS!!

short answer: no
long answer: read the other posts in the thunderbolt forums for similar questions.
Side note: there are some verizon phones that are "world phones" that have sim cards in them. The droid 2 I think some of the blackberries do. I would return and get one if you can.

different type of SIM card. Thunderbolt has one for 4g only. Verizon uses CDMA for 3g and LTE for 4g, and probably some other band for voice. ATT uses GSM for 3g and HSPA+ for 4g. So they are completely NOT compatible.
ATT will be eventually going to LTE, but they could be dicks about it and choose a different frequency of LTE than verizon to prevent people from switching networks (since there's more than one to pick from), thus making it incompatible still.
Currently, all voice is CDMA on verizon still and data is CDMA as mentioned if it's 3g and LTE if it's 4g (which is what the sim card uses as it is the next incarnation of GSM). Next year they will be transitioning to voice over LTE.
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.
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

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.
