Please talk here about GSM and CDMA:
What would you like to know? GSM phones have SIM cards, CDMA do not.

He doesn't need any advice, there are some guys flooding his rom thread with a fight about which is better, that's why he opened this one.
But thx anyway
Its pretty harsh really. From what info I've gathered the CDMA WFS is easy to S-Off, no XTC-Clip needed, but then harder to code custom ROMs for or something like that so they get less options. Brilliant idea by HTC[sarcasm].
It's like, they dangling a carrot in front of CDMA users but inside the carrot is super-aids! Not cool HTC, not cool at all!
Anyone know if there are any other advantages to the CDMA version other than you can S-Off without the Clip. Does not having a Sim-Card make any big difference? GSM/CDMA for battery life?
I have a cdma phone and I heard its slightly smaller than the gsm so we need smaller cases

What I've always wondered is - do CDMA owners have a choice before they buy? If so, why didn't they go for the GSM option?

No, Verizon and Sprint are only CDMA carriers. They do not offer a GSM service.

How pathetic. That explains a lot now. (I never knew why Sprint & Verizon & At&T had their own models).
Very good to know.

Anyway, to sum things up:
GSM = Good Sized Mobile
CDMA = Crazy Diabolical Massive Android
Until recently I have been with Sprint. And I am located in South Florida.
I am considering going with Simple Mobile as I'm told that T-Mobile has one of the best data speeds in this area. And I want to get a Galaxy S3 as the phone to use with this service.
Can anyone here advise as to whether this would work with Simple Mobile (I called them but they won't say anything only that they don't don't support it - meaning they don't sell it so don't bother them), at what speeds?
I also assume that I must get the T-Mobile version of this phone. That seems quite difficult unless I want to pay a big premium to T-Mobile, who charges much more than say AT&T for their version. So if anyone has any suggestions where I can get one (I would prefer a store, not eBay)?
Thanks
try the xda marketplace
edit: nvm just saw you dont have enough posts.
I read that the Sprint variant of the S3 would work on T-Mobile. You just have to unlock the phone I believe.

I remember negri sells the phone for $599 unlocked. That's the cheapest I've seen for the TMobile version. It's not cheaper by much but it's unlocked and you may save on taxes.

Sprint is cdma and T-Mobile is GSM. How are you going to stick a sim card in that sprint phone?
Sent from my SPH-D710 using xda app-developers app
My wife is using it on Simple Mobile. It works great.
Simple Mobile is a Mvno of t-mobile so you don't need to have an unlocked T999. Just change the apn. A's far as speeds. I live in Central Florida and I get the same speeds as t-mobile. I recommended. As far as where to buy the phone. I went to t-mobile and paid $599 for it. Haven't really seen it cheaper.

It does have a sim slot but it's not user accessible.
It's hidden behind the plastic under the battery.
Sprint has taken this approach with all there LTE devices.
The only exception may be the Photon Q since it's touted as being a global device.

nope.
Not sure why you even think it would work. There is no GSM radio in the phone.
Sent from my Nexus 7 using Tapatalk 2
Unfortunately the technology that Verizon and AT&T use for their networks are different and not compatible with each other. GSM phones (AT&T, T-Mobile) can be used on different networks but CDMA (Verizon, Sprint) are usually only able to operate on the network they are sold on. CDMA technology is a bit strange because you can't even switch devices between Sprint's and Verizon's networks.

Because misinformed users often think a sim slot indicates the phone is GSM based. Even now, a lot of people are shocked and appalled when I tell them my Verizon phone needs a sim card.

we did say no and then you questioned us. thats when you get a more jerk filled answer.
IDK why your bashing him, he didn't say," nooooo it does work on AT&T!"
He said after you said no,"It has a sim card slot why wouldn't it work?"
All you got to do is answer that question. This is XDA, not BAA(Be an ass).
If he has a question just answer. End of story. Ik this is an obvious answer and he could've dug harder on Google, but who cares whatever, just answer it.

Ok ima try to keep it as short and simple as i can. I have a stock T-999 s3 tweaked to perfection running of Net-10 prepaid with the bring your own sim. Not only that I have it network unlocked so no matter what sim i place in weather its AT&T, t-Mobile, straight talk ect. i have service, each service i can critique to its best functions. Now heres my point. I also have a US Cellular galaxy S3 , rooted, and no matter what i do or try i cannot get this specific model to run a gsm provider via sim card. Im no wiz, but i get the idea, and my idea is to take this phone that is not supposed to operate on gsm carriers and make it operate. A recent example of success doing so was with my Droid Razr Maxx HD, i was able to successfully root the phone but as you all know verizon does not support us gsm carriers within the united states , or even on their network for that matter they block it. however after flashing a different modem, i am currently running t-mobile with great service! So any talk of "its impossible" i dont need, negitivity is not needed. i am fresh to this stuff but it fascinates me. cutting to the chase, what needs to be done to this sgs3 model #SCH-R530U to make it operate and function on a gsm carrier within the United states. Hacking Manipulating and tricking is all welcome that what were all about. Ive tried several things changing to global mode, gsm only,, faking gps positions to outside the u.s. and apn settings among countless hours beyond and im at a loss.. please im open to ideas and suggestions hopefully one day we make every model capable as nevery other
I believe the issue you are facing is because that particular S3 does not contain the necessary GSM radio chip needed to use those networks.
According to this (and its a wiki so it could be wrong):
http://en.m.wikipedia.org/wiki/Samsung_Galaxy_S_III
That S3 does not have any GSM bands for 2G or 3G.
However, once T-Mobile launches its 4G LTE on the AWS band, it should work...assuming the 4G network is both voice & data over LTE AWS.
The RAZR does work cause it does have the necessary 2G/3G GSM radio chip.

Simply put, the Verizon galaxy s3 is the only variant that has both CDMA and GSM bands. So if you wanted to do what you're saying, it would be most possible with the Verizon variant.
But for what you want to do, you'll need a world phone. And I believe the Verizon s3 is a world phone. Just gotta "hack" the GSM bands. Since they aren't active by default. But your T-Mobile att s3 will never work on CDMA. Also not lte will most likely not work on other carriers.

I'm wanting to join my fiance's plan on sprint. I have a verison galaxy s3 currently. Am I able to just flash a sprint rom and have them activate it on the sprint network, or will I need to get a new phone when the time comes? I really don't want to have to get a new one with that expense if I don't have to.

As far as I'm aware, it will not work like that. You most likely will have to get a new phone.

Incorrect. Sprint uses a SIM for their LTE as well (all the carriers do). It's just embedded and not visible. Doesn't really matter to O.P, as he/she would need to get a Sprint phone anyway.

Come on that's splitting hairs..a SIM card is recognized as removable to allow portability of a device from one account to another (or even carrier to another) just by swapping the SIM card. Let's not confuse the guy. Sprint SGS3 does not have a SIM card, it has an imbedded chip. Otherwise it would be no issue but having the right sized screwdriver to remove and swap a Sprint 'SIM card' with a Verizon one. The hardware is different, thus you cannot do this.

Technically it's not the same, they have the same function but an embedded sim looks more like a chip soldered to the board and not an SD cardish shaped card. They serve the same function but do it slightly different. Kind of like a car and a truck, they both have 4 wheels and serve the same purpose (transportation) but they technically aren't the same thing. The main difference is removable sims are easily reprogrammed, while an embedded sim isn't(has to be detached from the board and put in a special reader that unlocks the programming function). I guess embedded sims would be considered more secure than a removable from several standpoints. User standpoint its not easily swapped out with another in the event of theft, and the data stored on it isn't as easily accessible to a thief. From the carrier standpoint its not as easy to reprogram and impossible to swap so the device can be unlocked to work on another carrier.
I like to break stuff!

Sorry, you're wrong.
Whether hairs are being split or not, this statement "Verizon uses sim cards for their LTE phones while sprint doesn't." is factually wrong. Sprint does use a SIM for their LTE.
Like someone else pointed out, would you say that one phone with a non-removable battery DOES NOT TECHNICALLY use a battery versus a phone with a removable battery, just because etc etc...?
...and what would swapping a Sprint SIM with Verizon achieve? Sprint's LTE is on 1900mhz and Verizon is on 700mhz? You do realize that...
