[R&D] my T-Mobile Samsung Galaxy S II shows LTE bands

Hey guys i bought the Samsung Galaxy S II from T-Mobile thinking that has HSPA+ bands I, IV and V.. like the box and website says.
Here we use HSPA+ band V (850) so, i inserted my sim card but i only pick 3G bands ( HSDPA )
Checking the bands that the phone has using *#2263# i noticed that i have WCDMA, GSM but also i have LTE bands ...
I never heard that T-Mobile Galaxy S II has LTE bands..
Any ideas why it says LTE instead of HSPA+?

YES, I WAS RIGHT! Samsung was to lazy to change the modem between the skyrocket and the T-Mo SGSII, so if you flashed one of our modems, you'd technically have a functional LTE radio.
Wow, this is crazy!

You'd have to flash a Skyrocket radio, because when I was using a T-Mobile radio, it wouldn't connect to LTE.
But that means, if I'm right, the Skyrocket and T-Mo SGS II have support for 850, 900, 1700, 1900, and 2100 HSPA+.... that's a pentaband phone.
****. YES.

Go ahead and try it folks.

Now I'm intrigued... does the roaming agreement between the 2 carriers say anything about LTE?

Your talking about the post merger agreement right? It just may... and those of us on T-Mobile may be able to hijack Lte once the agreements are in place lol.
Its cool how there are so many similarities between the two phones. They are almost identical which is great for developement.

Yeah, but I don't think AT&T would allow another carrier to roam on a very new LTE network, especially when they don't even have 10% of their own customers on the network.
And it's really cool, because they are the same phone. xD
Although, I don't know why our accelerometer is flipped.

Maybe that is the only stipulation AT&T put out there between both phones?

Hey guys..if it helps I have T-Mobile galaxy s2 and skyrocket from att ..would like to test out and see if this may work. Not to sure if there's any lte support in Connecticut area..but this would be a niffty find...thanks op

Could be, but with the short amount of time between release of the 2 phones, Samsung must have developed 2 phones, same hardware, flipped the accelerometer in one, and branded one AT&T, and the other T-Mobile.
Gotta say, that's a great way to save with development.

maybe you are right. i just bought this phone so, its probably the new version.. however.. here in peru where i am at, we use HSPA+ 850 but i cant pick that signal .. only 3G ( HSDPA ).. so means, TMO SGS II is penta 3G band but only One band HSPA+ ?

No, try this.
Go to the skyrocket forums, find the radio thread, and flash one of those modems.
If I'm right, it should kick on the 850MHz portion of the radio

Even if u have hspa+ it will say 3g on this phone because ur carrier may only be supporting 21mbps and not 42. You probably are getting hspa+ speeds but ur phone just shows it as 3g

Theoretically it should work. Lol, an ode to the original vibrant, sometimes their laziness pays off! I've noticed the sensation has LTE mentioned also. Haven't dug if it but I wonder if it actuall does support LTE ? If I'm not mistaken LTE uses AWS protocol right?

Galaxy nexus and 850 mhz bands

Hi people recently I trade my Motorola razr with a galaxy nexus, the guy who trade it was using the phone with movistar, in my country it operates on 850 mhz. I use other carrier claro also working on 850 mhz. But with the Sims of that operator (claro) I got no service at all. Maybe it is a old thread but don't know how to search for it and honestly the galaxy nexus has a big forum.
Hope you can help me because I got a plan on claro and don't want to change operators.

It look like you will have to do some flashing, though I am not in your area so I don't know which specific image or radio you need.

thanks for the answers, i was using my xda tablet app and its harder to search, well i search a little, my problem maybe is because the radio installed, i got xx radio which is european, supports 850 but someway it can be causing the probelm with other sim. I find some radios for US and Canada but they are listed for ICS, it can work with jelly bean?

Yes. You should be able to use almost any radio.
And by the way, XX radios are not only for Europe. U.S. devices ship with XX radios as well.

It's probably not related to the firmware on your phone. Did you try it out with a SIM of a different provider?

yes the sims from the other carrier works, both operates on 850mhz

Then it certainly has nothing to do with your device or the firmware. It is either related to your SIM or to your carrier account or a network issue.

Any suggestion to solve this problem? i speak with costumer service of my operator and they told me that theres no support for devices not sold by them, so im stuck with this phone with no signal at all.

I returned the phone, really like it but for me is not working.

T999 -vs- I9300 International

This is not a rant nor a rave post, it's all about one's opinion regarding the difference between the International version S3 and the T-mobile S3.
I have had my S3 T999 UNLOCKED version for a while now, it's a 16gig model and after Flashing so many ROM's and whatnot, I am seriously considering getting the International version.
My decision is NOT based on the HARDWARE difference between the 2, it's based on the SOFTWARE alone.
IMHO, It's totally inconceivable to expect a device like a cellphone to be a Speed demon or have the Fastest and Latest super this or super that. I don't think anyone BOUGHT their device for that reason alone so what did we buy it for in the first place ?
1. Reliable Communication should be the #1 top reason for everyone.
2. Dependability should be #2, I would believe.
3. Utility as a personal entertainment device to pass the time when one is bored.
There are other reasons that I can't think of but it's safe to say that the T-mobile S3 is different in 1 regard, between the other GSM carriers, T-mobile has 1 different frequency, don't quote me but I think it's the 2100 .
Would any of you care to share your opinion if you had to go back and change your mind would you have gotten an UNLOCKED S3 International over the T-mobile's version, disregarding the hardware aspects of the 2 ?
P.S. Oh and BTW, Is there any end users and/or Developers that have both devices ?
Regarding the Software, I just would like to have the Essential apps that 1 needs, not all this other B$ that is dependent of the other bloated apps, I think everyone knows what am referring too, right ?
If Wild or Doc, reads this, maybe we can ask for a ROM that let's us install the apps we want on our devices via the Aroma installer, would be nice right pps ?

Yes, the T-Mobile version is different in that it lacks LTE and it adds the AWS (1700/2100) band. You never really said why you made a decision to change devices, just that you had made a decision. Personally, I am happy with the phone I have, but I am on T-Mobile, so the T999 that I have is an obvious choice. Are you on T-Mobile? If you are, think carefully before you get another version, since you probably won't get the data speeds you expect with any other GS3 version, at least not at this time.

I don't understand what are you trying to tell us, but if you going with international version make sure you get a career like Att the support hspa, otherwise you will be stuck on edge for tmobile, until they re framed their network
Sent from my SGH-T999 using Tapatalk 2

Only reason to NOT get Internation version is simply as stated before of the AWS band, you going to be on EDGE with the internation version no matter where in the US you go too. So what is your reason for switching anyway?? Because your post is confusing

Op makes no sense...or needs to be edited....

I did not get what the OP wants to say. But for me. I got the T999 mainly because of the wificalling feature for tmobile.

Yeah but not everyone lives in Vegas.. and outside of Vegas 1900mhz support is miniscule.

Hello guys, i would like your advice on this matter. I want to order a t999 because of the specs i find more powerful, therefore i want to know if i can use it in Europe with my local (vodafone Romania) carrier...After i will get it unlock i mean.
I recently find out that my carrier uses 900 mHz network GSM.

Well i have both t999 & international. i cant take the slow speeds of the international so i use the T999 as my daily phone but if i had 4g i would totally use my GT-I9300 to me there's a difference

sleepy13909, Thanks for your reply.
I am a T-mobile customer and I have the T999 but as I mentioned, I didn't buy the device of the download speed, I bought it because I thought it was a RELIABLE COMMUNICATION DEVICE.
Since, I've not ventured out into the I9300 area of the forums here, I was wondering how much Bloat is on the International version compared to the T-mobile ?

This is really important for me. You have SEEN his Note get 4g here in Vegas? My gt-i9300 is in transit as I type this so I really wanna know if 1900 band will really supply me at least 3g speeds as of 9.24.12. Because if they're both 1900 baseband phones I don't see why my sgs3 gt-i9300 couldn't get it. Btw I live in eastern side of town. Around Hollywood and lake Mead. Around which side of town does he get those speeds?

Lets Make it happen, Any model Galaxy3 on any network?

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.

Sorry, but it's not going to work with this phone.
Orange Dominicana uses the 900 band frequency for 3g (WCDMA). On this phone that band is locked for being used with 2g (GSM). That's why you're getting Edge.
Unfortunately, the T-Mobile version of this phone also locked the 900 band for GSM. That means the NV data hack won't work for you either.
Sorry. Hope that explains it, and I hope they at least launch LTE service on a compatible band for you.
