4G Antenna - Galaxy S III Q&A, Help & Troubleshooting

All S3 has the 4G antenna, they just pick up different data freq? I got the i9300 and currently reside in US under AT&T. KNow if there are anny ways to receive 4G? The phone according to specs can only do 4G in europe and such, but any one have any idea?

you talking about the Us variant of the S3 (Qualcomm s4 version) or the international version (Exynos quad core version)???

i9300 does not have LTE. The max you get with it is hspa+
Unwanted info: As of today you will get edge only on T Mo US.

where did you find that spec??? It's wrong.. international version doesn't have a LTE/4G Antenna.
Only the Korean (exynos) and the US (qualcomm s4) versions have 4G/LTE as far as I know.
Most of the websites say the s3 is 4G friendly or regional, etc., All that means is it's supported in certain regions (south Korea, US)

The i9300 does have the 4g bands except 4g lte bands for AT&T in the US.

We don't have 4G LTE bands, but we do have "faux" G bands though.

No, the T-Mobile version will have a different hardware radio that supports their frequencies. This is no way and there never will be a way to use the I9100 on T-Mobile US 3G.

Look up the current Galaxy S II on samsung.com and it will not list the 1700mhz umts band. This band is what T-Mobile US uses for 3G.
Or you can try searching the xda forums for the numerous other threads explaining this.....

Look at the bands in the specs - if you don't see UMTS1700, it won't work.
And I have NEVER seen that in the specs for ANY AT&T phone, EVER.
In rare situations, T-Mobile phones supported one (but not both) AT&T bands, but I've never seen any AT&T phone support T-Mo bands.

T-Mobile's AWS bands aren't typically supported. AWS isn't even used in Asia or Europe. T-Mobile's SGS2 does have AT&T's bands but not vice versa. But it's a stretch even calling T-Mobile's version an SGS2.
How about 3G? Does Tmobile support 3G on AT&T phone, since i read both phone have 2100 UMTS.
Thanks

Vibrant only supported one of the bands (1900), so it only worked on att 3G in some markets, not everywhere. Some markets only use 850.

No. 3G and 4G use the same bands. You MUST have 1700 AWS support in order to get T-Mo 3G or 4G. Good luck with that. Only T-mo or some Canandian phones support AWS.

You'll get EDGE/GPRS speeds. Typically between 256 and 512K. To get anything higher you'll need a phone that supports 1700/2100 of which there aren't many other than the one's offered by T-Mobile itself.
Simple answer: No.
You will only get EDGE speed on any AT&T phones. There aren't many phones with 1700 band besides T-Mobile phones.
It's funny how T-Mobile's "SGS2" supports AT&T's bands, but not the other way around. But then again their "SGS2" seems more like an Amaze IMO since it's using the darn S3 & not Exynos >:l (points at tmobile). I really wished Sammy could fix the Exynos, so it could support Tmo, because it feels wrong when Sammy teams up with Qualcomm....End of rant.
The only reason T-mo version uses Qualcomm chip is because it needs the 42mbps HSPA+ radio from Qualcomm. The upcoming LTE version of GS2 will also use Qualcomm chip because it needs to use the Qualcomm LTE chip.

The Korean Celox, on which the TSGS2 is based, is an LTE device and using a Qualcomm chip. The two recently announced Korean SGS2 models will be LTE and using a 1.5Ghz version of the Exynos chip. Samsung went with Qualcomm for the TSGS2 and Celox either to shorten time to market or the projected quantities weren't sufficient to modify Exynos. Evolutions of Exynos will continue to power Samsung's flagship phones and tablets starting with the G-Note and G-Tab 7.7.

[Q] GT-I9100 /w AWS UTMS band?

I've read that the AT&T version of the SGSII (Skyrocket) and Galaxy Note can be flashed with the Tmo SGSII modem and work. Does anyone know if this can be done on the international SGSII (GT-I9100)?
I have this, and was on AT&T, but now on T-Mobile. I still love this phone and want to use it on Tmo on their HSPA+ network.
I've searched, and nothing has come up. I wonder how much hardware parts these variants share with the "original".
Probably a Qualcomm Snapdragon S3 vs Exynos thing....

No. The GT-I9100 physically lacks the capability to receive one of the two necessary bands for AWS to receive high speed data on T-mobile USA's network.
The reason it works with the Skyrocket and the Note is because those two phones DO have the capability to receive both bands for AWS. (1700 and 2100 mhz UMTS)

how to check galaxy s3 is 4g-LTE activated or not?

Hi... How to check if my galaxy s3 is activated for 4g-LTE network as in the country I work right now dont have 4g-LTE but it is going to launch the 4G-LTE in few months...
Unless you bought yours in Korea and it has more angular shape like the S2, I doubt you own an LTE version.
It hasn't been launched outside Korea.

It its model (Menu --> Settings --> About Device --> Model number) is GT-I9300, it's the international version and it's not an LTE device.
If it's SGH-T999, it's the US T-Mobile version, you're in the wrong forums, and it's not an LTE device also.
If it's SGH-I747, it's the US AT&T version, you're in the wrong forums, and it's LTE-enabled.
If it's SCH-R530, SCH-I535 or SPH-L710, it's one of the US CDMA versions, you're in the wrong forums, and it's LTE-enabled.
If it's SGH-N064 (SC-06D), it is the Japanese NTT DoCoMo version, you're in the wrong forums, and it's LTE-enabled.
Finally, if it's SHV-E210K/L/S, it is the Korean version, which is the only quad-core, 2GB, LTE-enabled model. And you're in the wrong forums.

If you have the i9300 than you only have HSPA+.. no LTE.. but its still 4G..(more like 3.5G to be technical) Now if you lived in the Korean market and manage to get your hands on a LTE version then you have LTE where the bands are supported..

Thanks I have international and I can receive H+
anyone seeen me?
I just got thebsprin gs3 4g lte model and I too want to know how can we manually turn 4g on or off or simply verify it's on 4g. My epic 4g had a friggin checkbox you could see it was checked or jot but the gs3 doesn't. Still love the phone so far with one major hit, no ability to kove apps to SD. Is it just ke or does that seem stupid? Anyone know of abway to get this functionality back without rooting and if rooting is needed what's the likelihood I'll brick my phone? Never rooted, scares me
Easy way to check is to use the speed test app, if you get more than 40mbs, there's a good chance that you're on a lte network with lte access. One of my mates has an i9300 GT, 1G ram but gets 54mbs, so I'm at a loss as to what's going on there. I did the speed test for him on Telstra's network in Tassie... Checked in settings and it does use lte...

I have Korean s3 SHV-E210 L and it only connects to GPRS and 3G. When I select WCDMA only the network keeps on dropping out. Please tell me whether my phone is 4g compatible? I even do not get H+ network in this phone. I had s2 and it was having a great H+ network but this s3 only receives 3g forcefully. It has got 4.1.2 custom , 2GB RAM and 25 GB ROM. And can I upgrade it to kitkat?
I am sick of slow internet please help. Thanks admin n all.
Thanks.
The E210L is not a good match for either European or American bands, as it's tailored to LG U+'s CDMA (3GPP2)-based network. It is a bit of a surprise that it even works on GSM, much less on 3G.
IIRC the E210K is recommended in Europe.

I am in India and using Korean s3 LTE 2gb ram which doesn't receive H, H+. It only catches GPRS and forcefully 3G with an speed of maximum 1 mbps. I have contacted Telecom provider and am sure it's not there fault as apart from this phone other phones work perfectly fine. Please help me to improve the speed of my cell data internet as it can support Upton 21mbps. I am sick of slow internet and network dropouts. Thanks. ?
AFAIK India uses the same frequencies as Europe (same ITU region). So, you will likely need E210K or E210S (both GSM devices) to get 3g and 4g, not E210L, which is a CDMA phone. Not all Korean 4G S3s are the same.
Also, your SIM could be too old, or your APN settings wrong. However, it sounds like your device can only receive a less-used frequency band for 3g, with less than normal coverage - a common issue with LG U+ devices.

S3 Network issue! Slow internet!
I've S3 E210 L and when I check my APN settings it does have LTE option under Bearer but currently my Telecom provider doesn't support 4g. However they do provide 3G with a great speed. I hv used it on other mobiles and it works great . It's just this phone gets only G when selected GSM/WCDMA automode. When I manually select WCDMA only it gets 3G but very slow speed and it drops out very frequently. The maximum speed which I have received is around 1 mbps only.
Please provide me with a resolution how I can I get good bandwith/speed. ?

The short answer is no. First you divide the phones into two groups; GSM and CDMA which are incompatible networks, apart from limited overlap on the data side. Note that Sprint in particular, locks down their CDMA phones pretty tight so that it is very difficult to use them on other networks, particularly competing domestic CDMA carriers.
GSM phones, at least the higher end models like the S5 are multi band and will work on pretty much all GSM networks. However each model is optimized for a given carrier's frequencies. So your phone may roam or (if unlocked) accept a SIM from another network, it probably won't work on all of the frequencies of the other network. The effect of that may not be much in a dense urban area, perhaps a little more network congestion or slower data speeds. But in fringe areas served by only one frequency, it could mean no coverage for the foreign handset.
The TMobile model is one of the best, generally speaking, in that it is capable of operating on more frequency bands than most other models. However what is best is subjective depending on where you want to use it and what model you have in hand. The Samsung support site lists the frequency bands that each variant will work on and you can see that they vary between carriers.
Interestingly it appears that the GSM S5's are manufactured with the hardware capability to operate on all GSM and LTE bands. But the different models only enable the frequencies used on the native carrier. Which is to say marketing (or by a real stretch, perhaps cost saving) initiatives are locking us out of better roaming capabilities.

Well again what you say is only correct for certain countries in asia. Not to single you out but there is a lot of misinformation, usually assumptions on this subject and it's productive to clarify the facts.
There were both LTE and non-LTE versions of the Exynos (4 core) S3. The GT-I9300[N/T], SHV-E210K/L/S and SGH-N035 had 4 cores and LTE and the GT-I9300[N] had 4 cores without LTE support. Not to mention that various asian counties like Japan and Australia use the dual core Qualcomm S3 with LTE. So it's not as clearly delineated as you believe.
You also suggested that it costs more to add additional frequency band support to a S5 variant. But this isn't so because the S5 uses WRL-1625 transceiver chipset which has unified support for all GSM and LTE bands. So it costs nothing extra in hardware to add additional bands.
One could argue that omitting secondary parts such as an antenna in a variant intended for a region that doesn't use LTE at all (if such exists) could make unified support moot. But the reality is that increased manufacturing and logistical costs of changing the hardware provisioning on variant handsets is usually prohibitive. It's generally believed that band limitations between variants reside in firmware with the purpose of detering grey market sales and carrier churn.

No, most of the non-LTE asian carriers are using HSPA+ networks which are considerably faster than Edge. The faster HSPA+ implentations are characterized as 42 Mbps networks, which is as fast as some LTE footprints. Advanced LTE rollouts however can double those speeds.
.
I had several people ask me about real world LTE speeds. All I can say is that speeds are highly dependent on carrier networks and will vary considerably between carriers and quite a bit by location as well. One LTE network might see speeds < 5 Mbps while another may be twenty times that fast.
I am seeing 60 Mbps typical speeds with my LTE and ~ 90 Mbps with a strong signal in larger cities. Carrier aggregation which is just rolling out now (and supported by the S5) should see some networks achieving 125+ Mbps speeds.

Does anyone know for sure if this will work with T-Mobile? It appears to have all the bands to support T-Mobile, but I guess what I'm asking is what firmware do I download if I want to roll it back to KitKat 4.4.2? A link to the firmware would be fantastic.
This is the closest thing I've found for KitKat 4.4.2 on this SM-900M S5 that I have....but it's Uruguay. All the other firmwares are for South American countries too....

Whats the difference if i tell the program im one of the models offered? is there a different program i can use to access my black screen S5 thats not in debugging mode when plugged in? (i plug it in computer now and it doesnt recognize that theres files becuase its in "charge only" mode)
