Galaxy S III I9300 on T-Mobile USA - Galaxy S III Q&A, Help & Troubleshooting

Have any of you T-Mobile users had trouble getting 4G using the unlocked I9300? Before I got this I had the unlocked Galaxy Nexus and got 4G with no problem. For some reason my GSIII won't connect to 4G.

Because it doesn't support T-Mobile U.S.' AWS bands. You can get HSPA+ in the markets where they've re-farmed the 1900MHz spectrum. The GSM GN does support AWS.

galaxy s II works on tmobile 4g network usa??

I am really itching to get this phone, as my contract is going to be done within weeks. I know that the EU version wont support tmobile 4g. How about the Canadian version??? the bell/ virgin galaxy s II 4g. Would this version work tmo usa??
Check the bands. Google it. If they're the same then it will work. AT&T's 4G network will work with European and Canada's will also I believe.

that's the problem, I am new to this stuff and willing to learn. Let's start with what BAND is, and how do I check that BAND.
I am not 100% sure. But I believe that it well not work on T-Mobile USA 4G network. It uses different frequencies. If the SGS II ever comes out on Rogers then it will work on T-Mobile USA.

You are right. And once the merger goes through the T-Mobile 3 and 4g phones wont work on 3 or 4g. This was already stated by att and tmobile

By that time the Galaxy S III will come out lol. But I will definitely love the HSPA+ speeds on my SGS II.
If you really want it either:
1) Switch to AT&T, you will get 4G speeds
2) Wait for the Samsung Hercules to come out on T-Mobile (Should be this or next month)
In the end, all people who buy T-Mobile phones now will eventually suffer later on. ;D

International version of the SGS III (I9300) on US T-Mobile

I would highly appreciated if any one can help me with this, I have an HTC Amaze 4G on US T-mobile, and I would like to get the samsung galaxy s3 but the international version the (I9300) with the quad core. My question is would I be able to use it on t-mobile network with no issues especially on there 4G speed?

No, it wont work with Tmobiles HSPA, I think Tmo is changing their HSPA to 1900 next year so that would of been a different story, but for the moment its just not worth it.
Thank you very much....that's very disappointing....

AT&T 3G i9300 in USA?

Ok, so I had to sell my i9305 because of lack of any data connection above 2G/Edge on AT&T for my area due to frequencies that they use here.
How many people in the USA are using an unlocked international i9300 on AT&T and getting 3G+ data??

Nobody in the US has an i9300?

It works and you get hspa+
I'm on AT&T as well with the i9300 that I won from Engadget.com and it works just fine. H+ all the way for me as well.
Thanks guys, I appreciate the responses. I spent 700 beans on an i9305 to find out it didnt work. Just wanted to see if the i9300 worked. One more question, Do you guys have the LTE versions or the non-LTE?
Firstly, GT-I9300 supports 1900MHz for sure but 1900MHz WCDMA support on GT-I9305 is based on different region. For example your GT-I9305 has no 1900MHz 3G but the GT-I9305 sold in Hong Kong supports 1900MHz WCDMA.
Secondly, it is quite meaningless to buy LTE phone outside and use it in the US because only Bell and Rogers Wireless support LTE 2600MHz, you will not be able to use LTE network on AT&T.
You may use the any Korean LTE version(SHV-E210S/SHV-E210K/SHV-E210L) because the all supports 1900MHz WCDMA. Or otherwise, you may use the AT&T model of Galaxy S3.
I am using SHV-E210S, there is no SIM lock on the phone.

Thanks for the info, though I had an i9305 Hong Kong version and it did Not get 3G or 1900MHz, I could not even select it. I was hoping the 9300 would be different.

LG G2 Tmo or ATT: Which has more bands?

Hello,
ATT user here currently on Note 2. I'm planning on buying G2 off contract and I'm debating between ATT and Tmo. Verizon is out because although it has SIM card it won't access LTE on GSM.
I understand that Tmo has all the bands ATT does and more, is that true? Would that explain why it's $600 on Tmo site and $580 on ATT? I looked at their respective wiki's and product page but they don't provide consistent descriptions. If anyone can help it'd be greatly appreciated

I know the Moto X has more bands for Tmobile's version vs. AT&T. I wouldn't be surprised if the same is true for the LG G2 as well
From Wikipedia:
D800 ZNFD800 AT&T 850/1900/2100 LTE 2, 4, 5, 17
D801 ZNFD801 T-mobile 850/1700/1900/2100 LTE 2, 4, 17
TMO supports AWS, unlike AT&T. AT&T supports LTE band 5, unlike TMO.
this doesn't answer the OP's question, but, i have a sim unlocked att G2 and i can get 4G and 4G LTE service with my T-Mobile sim/account. coverage is not as good as at&t in my location.
Awesome, thanks Sacrosaint!
I went through the LTE wiki, it seems like 5 is not that prevalent. Seems like the Bahamas, South Korea, Belize...it seems to me that Tmo would be the better choice, no? What with its use of the AWS spectrum and all. I'm still on ATT for another year so I won't be jumping ship yet (by then I guess the G3 would be out...)
The only concern is whether ATT's LTE-A frequency can be grabbed by the Tmo version, whenever it launches...

I tried att lg g2 with my tmobile SIM it never gave me 4g/lte returned it back and got the new one from tmobile. Everything Is working fine on att I could only get 2g/edge and that is a known prob the att lg g2 does not have 1700 aws band for tmobile.

Hmm. So you have Tmo plan and the ATT model didn't get you any LTE at all?

Not sure of the truth to that. Verizon, T-mobile, and At&t all support LTE band 4 which is AWS 1700. It might be more likely a carrier lock that prevents you from getting full coverage?

LTE band 4 is AWS and supported by AT&T. The frequencies listed in the wiki are for 3G/UMTS coverage which AT&T doesn't support AWS.

I'm in AZ and actually purchased LG on day one that AT&T sold it. They did not want to sell out-right so I got a prepaid service and told them I would not activate until next month...Manager looked at me like I was a terrorist. Went outside and on my then GS4 went to an unlocker site and SIM UNLOCKED LG in about 25 mins. I tried two different APNs and one seems to be best as I have LTE mostly all over the valley!
SUMMERY
-Got phone before anyone else on TMObile
-Got phone at least $60+ cheaper W/taxes
-I can use the WIFI free hotspots of AT&T, always on the road...
-At work my LTE is 27-36mb down compared to 12on att co-workers, and Verizons 17MB on a different co-worker!
-At home my signal is a tiny bit spotty, oddly is only in my room ge 1-2 bars H+

Ah thank you for the clarification. So the Tmo version will get 3G coverage in areas the ATT version will not?
I called Tmo yesterday. They won't ask me a phone straight out, I have to buy a one month plan . Now I see why the prices on eBay are higher than the $600 listed. Just looking for a store that has the white model.

Oh I totally forgot about the wifi thing...is that an ATT service that works with our ATT plan, or will it know I'm using a Tmo phone and not let me connect? Not a big deal since I have 2 GB and always come under each month but itd be nice to have.

Well, since t-mobile's 3g/umts is predominantly on the AWS 1700 band, utilizing a t-mobile SIM on the at&t model will result in sparse coverage for 3g, short of roaming. I understand t-mobile has built out some of their 3g on 1900 as well so that would work for you. Based off of frequency support, I would say the t-mobile version is the better one to unlock and potentially use between at&t and t-mobile networks. LTE band 5 support doesn't buy you anything domestically.

Thank you everyone for your input . Guess Tmo it is.
Though...One wonders what their software support is like...I read that since they do wifi calling they're updates have to go through extra approval above and beyond the othercarriers because they have to deal with the FCC?

Here in the Bahamas we don't have LTE yet, but we're planning on covering the same spectrum as AT&T, bands as well.
no AT&T LTE on T-mo G2
I have an unlocked T-MO LG G2. I recently swithced to AT&T (which only benefit is greater coverage area bc HSPA+ is way slower than T-MO) however my phone is not showing 4G LTE only 4G. when i searched for networks the very first time it listed AT&T LTE but would not let me connect and now it doesn't even show up in the network search. Does the T-Mo variant block a certain frequency used for AT&T LTE ??

Incorrect. T-Mobile devices support ALL AT&T and T-Mobile bands, except LTE Band 5 (used by AT&T in a few rural areas). What's wrong is AT&T turns off LTE for non-AT&T devices. You have to call them up and give them the IMEI # of an AT&T-branded device (even if it's not yours and even if your SIM isn't in it/you don't plan on using it). They don't check after that.

International Verison with LTE?

tired of waiting on root... considering selling my mega for the international version. Do any of them support LTE on att? all im reading is HSP+?
The GT-I9205 is the only one that does LTE & it doesn't connect to AT&T at 4G
