With that do you think that a TBH esque hack could be developed to unlock VZN phones for Domestic GSM??
EDIT: Saw the thread below me, disregard please.

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.

I want this phone in the worst way to replace my cracked Droid x2. however there is zero chance I will be able to leave Verizon soon. is there anyway to get this phone to work on my existing Verizon plan. If I buy a unlocked cdma version of the phone?
thanks in advance.

The i9100 is not a CMDA phone so it will never work on Verizon. Biggest problem about Verizon for me (reason why I changed to AT&T) is that verizon phones only work for verizon phones and no other phones will work on Verizon, even sprint phones. ( I have heard some people had success from sprint to verizon, although ive never seen any proof)
I thought the us cellular and sprint S 2s used cdma. from what I can find on the internet its compatible with Verizon when unlocked but they wont activate it because of the esn.

I coudnt find dif forums for GSM and cdma s2's so i posted here.

Hardware wise, it may work, (unsure) but Verizon needs to add the MEID into their database to activate the phone, which is something they will not do. So, no unlocked phones will work on Verizon unless its a phone made for Verizon.
could I swap either that or the esn on the s2 with my cracked x2 and activate it that's way. I'm already paying for the contract I just wanna activate the s2 and abandon my x2. not try and have two phones working simultaneously

US Cellular's Galaxy S2 variant is the SCH-R760, and the Sprint variant (aka the Epic 4G Touch) is the SPH-D710. Both are CDMA phones.
This is the forum for the I9100. A different phone, which is a GSM phone.
You'd be better off asking your questions in the Epic 4g Touch forum. The US Cellular variant is not quite the same, but there are many similarities, and that forum is more appropriate.
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.

Hi,i am from Austria,i have a Droid Dna by Verizon and the Phone works fine here in Austria, 2G and 3G/HSDPA
This week the major carriers announced they will be unlocking their customers phones once their contracts run up.
Does this mean that my Verizon Galaxy s4 will work on a GSM network once it becomes unlocked by Verizon? Will I be able to use it on a carrier like T-Mobile?
its already unlocked, theres a guide on how to switch to tmobile in the general section
Hello everyone i was wondering if i can use a htc one m8 att on verizons network. I am aware that I may not be able to get 4glte is this true. If yes what apn do i use and what if the phone is not unlocked???
You won't even get voice service, or data by CDMA. The AT&T versions does not support CDMA.
Also, this (like all questions) belongs in the Q&A section. I'll notify the mods to move it.
