Does 4G needs an special antenna? - Galaxy S III Q&A, Help & Troubleshooting

I have red that i9300 do not support 4G networks. In my country they are deploying them, ao my question is:
Does 4G requires an special antenna not present in hardware or a modem upgrade can somehow make it possible?

an i9300 cannot pick up LTE networks or DC-HSPA. Your "4g" is a little ambigous but whatever they're rolling out, the i9300 wont get it as its hardware dependant.

By '4G' I assume you mean the LTE standard, which is the most common 4G standard I believe. In any case, the i9300 tops out at HSPA+, which is 3.5G as called by some. The support of LTE is entirely dependent on the chip on the phone, and unfortunately the i9300 lacks the 4G support unlike the American variants or the i9305.

Configuring different carriers

Hi,
I currently have an HTC Desire running on Puerto Rico's Open Mobile CDMA EvDo Rev. A network. It seems to me that the Galaxy S2 does support this network, and I had the Vibrant before and loved it, so I'm thinking about selling my phone for an S2.
Now, I've been searching info on how to configure / change carriers on the S2, as the phone is not available on mine. Haven't found that yet.
Anyone have a link / tutorial I can use?
Thanks!
The international sgs2 does not support CDMA, the sprint (USA) version of the sgs2 supports CDMA but you would have to check what bands your local carrier uses compared to sprint, and if you can activate an American phone on the network even if the bands match.

Galaxy S II 4G?

Just seen an ad on TV for Galaxy S II 4G? (In Australia)
sent from my Motorola XOOM using XDA Premium HD
it depends which version of SGS2? so far that i know the international i9100 isnt capable of receiving 4G... and so far that i know (might be wrong) the only SGS2 version that is capable of it is: Galaxy S II Epic 4G Touch... which is SPH-D710
I think the 4G is only compatible with the Telstra network.
What you mean?
4g=HSPA+
LTE is different....

Telstra are in the process of rolling out an LTE network.
Edit to add - As Victor said, only really useful on their network ATM. Voda/Optus to begin LTE rollout 'later this year' (apparently).
Further edit to add - Plus there will probably be about as much custom firmware for it as the I9100G (at best).

HSPA+ is evolved HSPA which isnt TRUE 4G... its more like 3.5G
LTE is true 4G..

Wrong 4G and LTE are totally different. New iPad only works with LTE variant of 4G which we don't have in OZ. We already have 3.5g and that is HSPA+.

Gt-I9300 international on U.S. T-mobile

Just curious, I have the international and I am on T-mobile in the U.S.
Will the I international ever be able to attain 4G Speeds on T-mobiles network? For instance once quad cores become the norm in phones (like they are on the verge of doing).
Or would I be better off selling and getting a T-mobile g3?
Thanks in advance.

well, as far as i know by end of this year we will be able to use 3g or hspa+ but for now i am sticking with 2g
or just change your mobile network, get straighttalk or att

Ok. 3g would be great. For the most part that is what is in most areas anyway. I just wasn't sure if it was our phone that didn't have the right radios or if it was T-mobile/other carriers that didn't have the right modems for our exynos.

International S3 does not have 4G chip in it
The max network speed that could be available with an international S3 is 21Mbps HSPA+

GT-i9300 has 4G?

This screenshots were sent from a friend that says that his cellphone is receiving 4G, however i also have the same GT-i9300 factory unlocked, but bought from the US. His S3 is bought from Orange Dominicana Carrier. We both are in the same network. But i only receive H+, while he receives 4G. Does this mean that there are GT-i9300 with LTE? Or mine is not configured properly?
IMPOSSIBRU!!!!
On a serious note, I was sent a text from T-Mobile uk saying that later this year I would be able to get 4G
Here's hoping
Regards
Jack
Edit: unfortunately after having restored a nandroid backup, I have lost the text, doesn't seem like i have a great deal of credibility now oh well
Yes or No then?
Yes or No then? because as u can see in the pictures, it appears he has 4G. And im pretty sure he has the GT-i9300.
The gt-i9300 only has hspa+, it may say 4g but it's hspa+.
The LTE version is the i9305 and isn't out yet.

Probably not, different frequencies for LTE, otherwise Sammy would just use the US version in European LTE markets.
Goes to show that the quad exynos is their preferred platform.

Getting Jellybean on the I9300 that works with T-mobile service in the United States.

Hey guys, I am in need of some help. I cannot seem to find the right keywords to return the search results I need.
I know there are plenty of battle tested Jellybean roms for the International (which I own). My problem is getting one that supports the kernels necessary for me to achieve service with my T-mobile provider her in America.
If anyone would be willing to link me to a JB Rom that will cure this ailment I would be deeply obliged.

Umm all the roms have the same frequencies. So u can use the latest leak.
Sent from either Galaxy S3 intl or Nexus 7
both on stock at the moment!!
Try any Rom in development section.

I installed the i9300XXDLI6 (4.1.1) FIRMWARE and I still have the issue of forever roaming. I can select t-mobile as my network and it registers. However, I have the roaming r above my signal bars because my phone thinks I am out of my "international" coverage zone.
So I need a link to a leaked jellybean and or created jellybean firmware that will work with T-mobile service in the U.S.
Hence the reason why I made this post. It is very easy to find a jellybean firmware that will work on an i9300 for a person that lives in the UK. However it is proving very difficult to do the same for an i9300 owner in the U.S.
Any help would be much obliged.

I would have thought that the modem was the problem .

I think your on to something here. I would love to know which modem will allow me to achieve service with T-mobile in America. I know personally that I can rule out the LFB and LG8 and LE8 modems. Any others you think are worth trying? Or do you know which one will for sure work? I have tried googling this before and was unable to yield any results. It would seem that owning a quad core phone for other T-mobile users in America was not a very high priority.

I am using Hot Mobile in Israel and have the same problem. I have tried the modem from the stock ROM with out any success which leads me to be believe the modem is NOT the issue. Anybody else have any ideas. I have the right CSC and the modem from stock ROM but it is stuck on roaming.
The hardware can only connect to certain frequencies, if your companies 3G band/s don't fall under those specific bands, you will ROAM or be on 2G...
You probably ARE roaming on AT&T or a small local GSM provider. A T-Mobile branded handset probably wouldn't show you that if they had a seamless roaming agreement. So you'd see E instead.
No matter what ROM you install on the i9300, it's not gonna fix your T-Mobile problem.

Shouldn't make a difference if you have an international factory unlocked GT-I9300. I originally had AT&T service which was roaming all of the time due to no coverage in my area. I dropped AT&T for a local pre-paid service which is owned by t-mobile, I am no longer roaming (on any rom i've flashed, custom or official). If you have an unlocked i9300, ANY rom in these forums will work on any carrier as long as you have the right sim card.
Power phone off, remove sim card. Power phone on for a few minutes. Pull battery for 30 seconds, reinsert sim card, insert battery, boot phone. Don't know much else you could do. Modem is not the issue if you are getting signal.
BTW, there are plenty of U.S. TMO gt-i9300 owners here, your the first to mention any issue like this.
Yupp plenty of US Tmobile GT-I9300 users on 2G. Hardware DOES NOT SUPPORT THE RIGHT BANDS...

I'm using omega. http://forum.xda-developers.com/showthread.php?t=1663656
So your using Omega, you live in America you have T-mobile, and yet you don't have a little r above your signal bars that means your roaming?

But when I didn't have root the roaming was never there. Or when I rooted and flashed the stock firmware I didn't have it. I don't think it is an issue of my data roaming or my phone not having service in my area. I'm not sure what it is but it has not always been there and only returns when I try to put a cool Rom on it like Omega or Viking.

I got a little excited when I was reading this thread and thinking that there was a way to enable the 1700mhz band so you could actually use the i9300 with T-Mobile here in the US.

You can it just is 2g data. Which is fine if you are on WiFi 90% of the time like me

I actually have a different problem. TMobile in Seattle has repurposed their 1900Mhz band for 3g. I've verified this by putting in my sim into an optimus 2 that has no support for 1700MHz, and I was able to connect to 3g fine. On my i9300, it just doesn't go above edge. I've played around with the radio forcing it to do WCDMA only, and the darn thing just wouldn't connect. The phone is mostly stock, I flashed it with CWM recovery, and SuperNexus. It's running the i9300XXLH1 baseband which it had when I got the phone. I still get edge and the reception is definitely a modest improvement over an aging nexus one which this replaced.
I think 1900 works in LA/San Francisco as well - if any of you guys have been able to connect to tmobile 3G on a i9300, can you share your config? Worst case, I think I should just try what the ATT guys are using, but any pointers before I start this wild goose chase will be useful :good:

I realize that the T999 version offers the best national coverage, but they've started work on refarming the frequency in Seattle. An optimus 2x which supports a subset of 3g bands of the i9300 was able to connect to tmobile 3g using my same sim card. I couldn't find a better news source, but this site says what Ive seen: okay, I can't post a url here, but the first google result for tmobile 1900mhz seattle. Basically, any AT&T 3g phone should work on tomobile in my area since the optimus experiment was successful.
