Question. about unlocking? - Galaxy S III Q&A, Help & Troubleshooting

if a nexus s3 puchased from verizon is purchased
then sim unlocked for use with tmobile
are the radios compatible with tmobiles 4g network speeds?
or is it a similar problem with the network only allowing edge similar to the iphone4s factory unlocked....

Won't work.
CDMA vs GSM.
Wait, what?? A nexus s3?

i meant a galaxy s3

sorry about that ... but really it wont work?

Nope. Not unless the Verizon one has GSM radios inside.
Why don't you just get a tmo or at&t one or buy one straight up?

Hehe. Even if (hypothetically) it has a GSM radio in it,
and hasn't got a SIM slot....

can i use rezound is gsm band?

i'm in thailand and my cousin will buy me this phone if it can be unlocked to use with gsm but i dunno it can use it or not
thanks and sorry for my bad english
Unfortunately the Rezound is not GSM compatible. I would suggest the Sensation XE as the closest alternative that is GSM capable.
This phone will work on a compatable cdma network but not on gsm network. Not a world phone.

any hopes of me just popping a sprint sim to my att note for some truly unlimited data sweetness?

Sprint will have sim cards for LTE. Still, this isn't likely. Even if it did work, a you would have is data. Your note cannot use Sprint's voice network.

FYI; The recently released Chinese version [Samsung SCH-i889 Galaxy Note] is CDMA, band compatible with Sprint/Verizon, as well as GSM.

Neither the i717 or N7000 models are CDMA band capable.
Note; Even if for some hypothetical reason they were LTE compatible and Sprint had a SIM, you would never get Voice/text.

Sprint Galaxy S 3 (USA) vs international galaxy s 3 question

Here is my issue. I am currently in the US. I might teach ESL overseas in Korea in January. I am not sure which phone to get. Will the USA one work over in Korea? Will thew international one work in the US?
It could work but Sprint has the radios locked.
Would developers be able to get them unlocked?
Buy international set

They propably can but the intl one supports more radio frequensies and is assembled to work worldwide so I'd buy it in any case rather than us version.
Sent from my GT-I9300 using xda app-developers app
The international one works in the US flawless... just not on all carriers... it works the best on AT&T if you want to use it in the US and get 4G(HSPA+)
You can use it on T-Mobile but you will have to settle for EDGE(2G)
Sent from my GT-I9300 using Tapatalk 2
It would work on most carriers which uses the international frequencies.
Not just AT&T for US. Works with Rogers, Fido, Telus, and Bell Mobility in Canada for instance.

Just a side note, HSPA+ is not 4G. It's still 3G. LTE/WiMax is 4G.
so which companies will it work with 4g/lte? Will it not work with Sprint? Anyone know any deals for the international version?
Sprint (and Verizon) is on an old CDMA network while the majority of the world is on GSM, you know, operating with a SIM card. If you're set on travelling, it's better to get any of the GSM-variant, that way, you can just pop in any sim card from any major carriers all over the world.
I currently have a photon which has a sim card slot in it. So the Galaxy s international wont work on Sprint? Damn I want to keep my SERO plan lol. So where can I get an international verison from? Also would I have to pay full price for it?
Does the photon has an active sim card in it? I'm assuming no. I've never used a dual-mode phone before (nor am I familiar with how they operate on different networks), so I dont know the ins-and-outs on how to get it activate for a GSM carrier.
Damn, now i have a headache just trying to figure out how it works to have an intl GSM phone on a network that is predominantly CDMA whom happens to offer a dual-mode phone on their network

The SIM in the Photon is just for roaming. Sprint does not use SIM cards - even their LTE phones have them embedded rather than user-accessible.
As the Sprint Galaxy S III is not a 'global' phone - i.e. does not have both GSM/UMTS and CDMA radios - do not purchase it if you have any intention of using it outside the US. CDMA is no longer a global technology.
Confuses me a little that people spend so much on devices without checking what networks they support. Ho-hum.

I777 working on tmobile?

Hey guys...Im doing a favor for a friend...he just got the I777 rooted ...but he wants to use it for Tmobile...what do i need to change for it to work with a custom rom...and then again can i port a rom from the tmobile S2 ...just modem?any input would be appreciated..
Edit:i have the E4GT on sprint...so i'm not really familiar with the gsm models...
While I should say use the search bar, all the information I've found is pretty outdated regarding this.
The simple answer is that you probably can't get it to work, at least not 3G/4G, if Edge is fine then you can unlock the phone with "Galaxy S Unlock" in the play store, just follow the directions listed, it's pretty simple.
The extended answer:
You might be able to depending on where you are. T-Mobile generally uses the 1700 MHz and 2100 MHz bands for 3G/4G, but the i777 doesn't use the 1700 MHz bands, instead it can use either 850, 1900, 2100 MHz bands for 3G/4G. However in preparation for LTE and just to increase bandwidth across 3G/4G they are starting to take some of their 1900 MHz spectrum from their edge networks and move it to 3G/4G/LTE. This has just started happening very recently and is currently in very few markets, however you may be in one of those, it is still expanding if you aren't but it may take a while. The only way you could know is if you took a T-Mobile sim card and put it in an unlocked i777 and if you get 3G/4G then you are good, otherwise you are stuck with Edge.

The S2 for ATT doesn't support 3g for T mobile and vice versa. There could be some weird instance as mentioned above where it could work but in most cases it won't.
Thank you very much for the update guys... I'll see what I can do...

Mostly true, T-Mobile's S2 should work with AT&T's network, you may have to flash a new radio but theoretically it should work.
You cannot port a T-Mobile ROM because T-Mobile does not have a similar gs2. The T-Mobile gs2 is the twin brother to the skyrocket

Sorry for the late response, I haven't been on here much lately.I live out in Little Elm, slightly past Frisco close to Lewisville Lake and 380/University. I am about to upgrade my phone again and give my wife the GS3. haven't decided between the GS4 and Note 2 yet.
I am in So.Cal and got 4G out of Edge half of the time from Tmobile ofcourse. The speed is around 7-10Mb/s or so
is there a rom ported from att to T-mobile

But as far as u know the Verizon galaxy s4 comes sim unlocked, since my cousin bring me one from the USA but my problem was how ti force 2g (gsm) use instead of 3g to save battery life, as this option is not available in the menu like the international galaxy s4

Hey guys...
So, the Verizon S4 is the model named SCH-I545 and it comes with a sim slot, right? Besides, it comes Internationally Unlocked, so it can be used on GSM networks around the world, correct?
Just one more question, does it work on the 850MHz Band for 3G?
I'm thinking on buying one also! Thanks!
I brought the vzw s4 back to india.. but its not working with either vodafone or airtel GSM.
After rooting and installing apn manager and titanium pro I was able to get the data working but that too only 3g.
But the voice n sms is still not working.
I too am lookiblng for a solution but didnt find any, inspite of this being a world phone.

Same issue in India
I am having the same issue. The phone picks up only data signal and not voice or SMS. I have a Note2 purchased from Verizon and it works perfect. I have rooted and was able to install an I9505 ROM Wamma Lite. It picked up the gsm signal for a moment and same issue occured. Can aI9505 modem be iinstalled using Odin which will make the gsm modem primary and CDMA secondary and allow gsm use for voice and SMS. Please help.

Yes, it will work on 850
Straight from Sammy.
"Frequencies and Data Type:
LTE: Bands 4/13
CDMA 1x/EVDO Rev.A: 800/1900MHz
HSPA+/UMTS: 850/900/1900/2100MHz
GSM: 850/900/1800/1900MHz"
I am using my i545 in both CDMA and GSM networks. Didn't try HDSPA, but EVDO Rev.A and even Rev.B, and GSM with EDGE - working properly without problems. Switching between networks - is in the Settings. My phone is connected to two different operators at the same time - to CDMA and GSM.

Are you using CDMA injected? I am using i-545 in Indonesia with local operator CDMA RUIM not successful, will try with CDMA injected.
