T-Mobile / Simple Mobile / Galaxy S3 ?

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?

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.

The Sprint version does not have the AWS bands that T-Mobile requires.

Not to mention the Sprint sim slot is sealed and inaccessible.

You didn't answer my question, how are you going to put a sim card in it. The sprint galaxy siii does not have a sim slot...

Also for Data?
Will it work for all the difference data protocols, and 2G, 3G, 4G?

Which phone is she using?
What plan (40, 50, 60) does she have? What data speeds is she getting?

No. It doesn't have the AWS bands that T-Mobile requires. And they don't have "4G".

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.

There is no sim slot. There is an embedded lte chip in there but no slot.

So she did get 4G from simple mobile or only edge speed?
Also did she get MMS problem? I saw someone open a thread says he have MMS issue. (http://forum.xda-developers.com/showthread.php?t=1791451)

I have no idea. But a guess would be due to the fact the iPhone SIM is not an LTE SIM. AKA, not compatible with your phone.

Yes need a new sim card. If not in LTE area you can use the HSDPA APN and get 3g speeds.

Sim won't matter, if your coming from an iPhone and didn't change your plan changes are if you look on your s3 its trying to use PTA but you aren't setup for it yet. If you change it to WAP or PHONE it should work or call att change your plan then PTA will work

The answer to this question is simple...and you could have easily searched to find the answer....iphone needs iphone data plan gs3 needs lte data plan...the mini sim is standard...there isnt a special iphone sim etc....next time try searching.....

Call at&t and tell them to switch you to a lte plan. Done.
Sent from my SAMSUNG-SGH-I747 using xda premium

Ah, makes sense. I thought it would at least get 3G service but i guess not. No worries. Ill call them today.

You should be getting at least 3g. Check your apn settings.

How about even simpler .. if phones are locked.. ATT locks phones to sim card and it won't work with a different one unless you unlock it.

You DO need a new sim card. This happened to my friend a few days ago.

IPhone and androids use a different data plan. You need to get switched to an android data plan.
Sent from my SAMSUNG-SGH-I747 using xda premium

If your sim is blue and white, you need a new one. If it's orange, your fine. Just call and have them switch you from the I phone data to the lte data plan.

Switching lte on

Hi friends who ever bought the t-mobile galaxy note can u try this option to check whether u can change the settings for data connection .I have a galaxy s3 where I used to this option to switch off lte to conserve battery .it worked fine.if this process works and u get the options to change connection type then you are good to buy t-mobile galaxy note 2 to use lte on at&t because I heard both t-mobile and at&t note versions has same chip inside but lte is temporarily disabled in t-mobile version .
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G) and you will have lte too
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.

Great, let me do this now so I'll ready when Tmobile turns on LTE in 2 years
Sent from my SPH-L900 using xda app-developers app

Fwiw I believe you can do this without rebooting.
At least when switching the gsm radio bands. I often check 1900 mhz in my area of nyc by doing #*2263#
I have done this for Lte and it just says no service. Perhaps I should get at&t to show up but this far it hasn't worked.
I'm interested in what other people know about this!

If I click the SIM it doesn't come out enough (hits the battery) to tell me SIM removed . No dice on that approach for me.

You can select bands from any Samsung Galaxy device (that I've tried) by entering this code into the dialer. *#*#197328640#*#*
A menu pops up which give you lots of options. To get to band options, choose Debug Screen, Phone Control, Network Control, Band Selection. Don't get excited, every device I've seen has an LTE option in there, but that doesn't mean your phone has LTE hardware.

Another for the SIM not coming out far enough. Also, with the *#197328640#, the 'Debug Screen' was under UMTS.
My GN2 is carrier unlocked and I have the SIM from my AT&T iPhone4 in it. I'm not sure that SIM would even be LTE compatible anyhow since all I had with the iPhone4 was 3G.

i try but get no signal guess we have to wait

any update if its working on att

i dont think it ever will lol

If the battery blocks the SIM, can't you just take the SIM out, boot up the phone with no SIM, and do the same thing?

If this T-Mobile version physically HAS the LTE radio that AT&T uses, does anyone know what it would take to get it working on AT&T's LTE?

Well first we _still_ need to get a working lte at&t sim card into the phone and see what happens.

I have one, of course not with me. Will try tonight and report back.

It has to be feature enabled at activation. For example, I am coming from a GS2. I cut my GS2 sim to fit the GS3. Everything worked perfectly except for LTE. I had to call and have the phone activated as an LTE enabled phone to get it working. I am on AT&T BTW.

I was also told that they have 'newer' sim cards that 'work better' with LTE as well. I was having issues with my SIM that came in my iPhone 4S, and when I moved to the SGS3 LTE was spotty. They gave me a new SIM at the AT&T store and it fixed all my issues. Not sure why it helps anything as a SIM should be a SIM should be a SIM, but apparently it does.

May be thats why coz my sim was activated at hspa for iphone need to activate in LTE mode i think

LTE on Fido

Here's my issue:
I have a Bell unlocked ZL that i currently use on fido. I have matched the band specs to other lte enabled devices on fido roster for lte compatibility (1700/2100mhz specifically because that's what my ZL has) but i'm not getting lte.
I ran in to this problem with my unlocked s3 and note, but for some reason I was able to get lte with my Nexus 4 (purchased from fido), which technically doesn't even support lte.
I have the correct answer settings and everything, but my phone just won't catch an lte signal.
Can anyone shed some light on this situation for me?

I';m with Fido, and there is no problem with LTE after upgrading to 4..2.2
from your screenshots i see the difference with my settings:
Name: Fido LTE
APN: ltemobile.apn
the rest is okay
MAY be it's case sensitive. can't guarantee that.
I had to set it manually.
the LTE sign appears when data is chosen.

As it turns out, the twat that sold me a "LTE sim" actually sold me a regular sim.
After buying a proper LTE sim and swapping it out, (no apn settings changed) I now have full LTE access.
With dual shock 3 support built in and the IR blaster for universal remote functionality, I'm 100% satisfied with my Xperia ZL.
Bugger all the haters that chirp about the screen and viewing angles. It's a tight ass phone and the tech behind it is well beyond par.
