Verizon is phasing out CDMA by year's end.
Does this mean we'll (finally) be able to use international (GSM only) versions with their service?
I understand they won't activate them but having a working SIM card from another device in hand, it would be nice if it would get service (minus a few things) on Exynos devices, for example.
They are not phasing it out they stoped activating 3g cdma and are goit to stop activating non hd voice 4g devices everything else will still be cmda

Just as the title asks, has anyone been able to unlock their Sprint Touch Pro 2, since Verizon's isnt out yet, to work on a US GSM carrier such as AT&T or T-Mobile?
Are the bands on the CDMA TP2s compatible with any of the 3G GSM networks, such as the 850/1700/1900/2100?
I just hate the fact that the GSM TP2s dont come with the 3.5mm headjack, but I wont bother with the CDMA TP2s if they cant work on a 3G GSM network.
Thanks!

from the specs that ive found online, especifically the "insanely detailed review" that comes up when doing a google serch for sprint thouch pro 2 review. the cdma version will only support edge speeds.
I tried a canadian CDMA TP2 on a canadian GSM provider and only saw the E icon too. I'm in Oz now and have H full time. There are some radio settings in the GSM section of the phone options that I am gonna play with when I get home to see if it makes any difference. But it looks like it doesnt support 3G speeds in NA. Maybe after hard-spl, maybe radios simply missing?
I used my unlocked Telus TP2 with AT&T when I roam in the states. My device is unlocked and I have an AT&T SIM card. The sad thing as is noted 3G does not work.... gotta get that thing to work in future fixes.
Hardware issues
It is a hardware issue and will never be fixed. Our crappy US companies force HTC to cripple devices to try to limit our choice of phones we use on their networks!
ok so i am so confused now, this is my problem: i have a sprint touch pro 2 and wanna put android on it, i am currently on t-mobile, which build do i use the GSM build or CDMA build? i installed both and still not getting my t-moble carrier signal
does sprint have sim card? If not, you should install cdma version
sprint doesnt have a sim card im have a tmobile sim car don it
You have a Sprint branded RHOD400, which is one of the CDMA Worldphone devices capable of operating on either CDMA or GSM. Because your device has both CDMA and GSM capabilities, as opposed to the GSM exclusive variants of the Rhodium, your device will be referred to as a CDMA device on this forum (despite the fact it has GSM capabilities).
Therefore, you should install the CDMA version. Though if you use Reefermattness's package, the only thing you should do differently from a GSM handset is to check the "Force CDMA" checkbox after selecting your keyboard map.
ok i redid it with the cdma version, now cant cannot to tmobile, sorry but im a real noob at this :/
is there a way to get it working with my tmobile sim(family mobile?)
Doubtful. I'm no dev but I don't think cdma systems and roms cant run on gsm phones. I may be wrong though.
We're comin from a pure power source.
The sim in the dual band phones I believe will only work if the cdma is activated that's how it worked on my blackberry tour world edition which was dual band GSM/cdma but the GSM wouldn't work without cdma being active so I doubt the design will work on tmo the dual band in it is basically for when you travel to a GSM only location but still have cdma service they come with a sprint sim card that basically unlocks roaming on GSM towers
We are legion, for we are many
Is the internal radio and SOC identical across all US carriers? (AT&T, Verizon, T-Mobile, Sprint)
I am looking to unlock a Sprint GS3 that I can get as an employee and use it on AT&T. (Apple appears to include both CDMA and GSM support in their 4S units) and I am hoping Samsung did the same to get the device out to all the carriers.
Thanks in advance!
Unfortunately, sprint opted to make the sim internal so it can't be swapped. If you see some of the video reviews out right now, it shows the sim slot missing.

I am not a professional on this but I believe that the SoC(processor, WiFi, Bluetooth, etc) is identical but the radios are different.
All the carriers use unique frequencies to communicate with their towers. Many carriers use separate protocols to communicate as well(HSPA+, CDMA, GSM) Its possible for 2 carriers to use the same protocol but they will always be using different frequencies.
Someone correct me if I am wrong, but I don't think its possible to re-program your phone to use a different frequency(i.e. change from 1900MHz to 800MHz)
I do not believe you can "unlock" a sprint phone. The radio simply will not work on any other carrier. Now, if said sprint phone were a "Global Phone", then it has an additional GSM radio in it as well. I don't know if this could be used to connect to another US carrier like AT&T though.
Hello,
I wanted to see if anyone has successfully SIM unlocked a T-Mobile Galaxy Note 3 to Sprint and everything working functionally.
Thank you,
Crap, I just wrote you like a page on this and the app crashed and lost all of it.
In short, it's definitely impossible. The GSM phones do not support any CDMA2000 2.5/3G frequencies which is what the US CDMA carriers use exclusively for voice and SMS.
Even if the T-mobile model supported the necessary frequency bands / CDMA2000 standard, Sprint would never allow it on their network. Sprint and Verizon only allow their own carrier branded phones on their networks. They each have a database of IMEIs for every phone they've ever sold. If your phone isn't on the list, they won't allow it on their network PERIOD. It doesn't matter if it's fully hardware compatible. They want to control every aspect of your mobile experience to extort more money out of you.
