Guys,
I am about to received my SGS 2 tomorrow.
I am in Australia on a 850mhz 3g (read not GSM) network (http://en.wikipedia.org/wiki/Next_G)
I know the phone supports this band, but I see some region firmwares floating around and am wondering if ALL firmwares support this band? Or is firmware specific.
Thanks guys.
Im on VR1.1 with everything else stock and next g is cool with me. Preordered from UK so mines from release.

Can I ask how you know your on Next G and not just 3g?
You can use non 850mhz Bands with Telstra and get std 3g.
Well im just assuming. But where i live all my family get 1bar with optus/3/voda whereas i get full bars. If u have a way for me to check ill have a look

not really sure how to check, the best I could figure out is install Network Info II and check network type
Should be HSDPA/UMTS?
I cant seem to find any tool to tell you exact frequency the phone is using.
It is not firmware dependent (If someone buys a Vodaphone branded SGS2 it is still going to work with NextG, but it will probably just be SIM locked). NextG is HSPA noted by the 'H+' symbol. When I was on Three is was just 'H' which is HSPDA.
If you dial *#*#4636#*#* and go phone information -> menu key -> Select Radio Band -> AUS2 Band
AUS2 is NextG 850Mhz, so if you get internet access on that, it is running NextG. The Phone Information section will also tell you your current network protocol also. If it is reporting UMTS then click the 'run ping test' button, it will flick over to HSPA
Hspa when data is being used
Umts when data is inactive

thanks guys.
Once it has charged I will put SIM in and test all this, very excited as moving from my HTC Desire
Sorry to dig this post up from the grave, but I'm about to move my SGSii to Telstra, as well.
I was wondering if you found benefit to these changes, and if you've changed anything further since.
Have you found any particular ROM/modem to be better (either in reception or battery life) than others.
And, finally, what sort of battery life do you get? I get about 14 hours before I have to plug it in, but I get terrible reception at work (I'm currently on 3), so I'm thinking that might have something to do with it.
Thanks heaps.
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.

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...

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.

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.
when in testing mode, i cannot get gsm only work. every time jump to wcdma preferred. anyone know how to fix this？

Unfortunately no...
The "ATT" note is carrier locked, and network locked as well.....not allowing the user to choose individual bands or frequencies.
To date, no rom or hack exists to truly unlock the ATT version for GSM only function....that I've ever found, and none of the play store apps will unlock the network either..
My last phone (HTC) would allow this switch on the network, but the samsung note will not..
But the International version of the note is unlocked for network switching between bands. ( I guess I should have got that one..LOL )
I too would love this feature, but it appears we are not going to get it.....g
Thank you for your reply. But i can use gsm only while i am using black star rom.
I think all official based rom could probably do it. *#2263# is the code to do it. But this code can only be used on official based rom.
On the contrary, cm 10 roms can use *#*#4636#*#* in which the gsm only mode is a fake one, i mean every time i click it, just switch back to wcdma preferred.

I traded my Atrix HD plus 50 dollars for this phone..which I think its a sweet deal plus it was unlocked phone so I can use T-Mobile for it. Now I need some help and there is way too much info about this and I don't know where to start Google is my friend,but I came here for shortcuts. I want to root, flash cwm, unlock bootloader and start flashing some rom which I will try to figure out myself. I need help with LTE
I changed my APN to fast.t-mobile.com,but I don't see any LTE signal. All I keep getting is 4G. Not sure if this phone even gets a H+ ( keep in mind i'm still on stock LG) What other settings I need to use to activate my LTE on the APN?
If I'm going to flash a ROM most likely PA or AOKP would this affect anything for carrier? I don't wanna messed up something and relock my phone.

Unfortunately if your not in the area where lte runs on the phones bands your SOL. The optimus G isnt aws so unless your in a big city there may not be any LTE. But 4g on the optimus G counts as HSPA+.

We have LTE in Phoenix AZ we had since it March 26,2013. Before the Optimus G. I was picking up LTE fine with my Motorola Atrix HD also with stock rom. I even flashed it with another rom. Still picking up LTE just fine. Of course I had to change APN to fast.t-mobile.com
Last night I rooted my Optimus G, unlocked bootloader and flash recovery. Wiped factory/reset, Wipe dalvik cache, flashed AOKP Rootbox JB 4.2, flashed Gapps w/ photosphere working, wipe dalvik cache. Success! Rom is great, no issues with it so far except LTE. I even downloaded LTE Settings from the Market no luck. All I get is H+
Do I need to flash a different radio or something? If I do can you or someone direct me to the right radio. Thanks
If I recalled tmobile uses band 4 for data speed. Optimus g does not. So no go I'm sorry. (1,3 and 5?) Does tmobile have actual lte yet? If so maybe modem may not support lte unless someone compiled one that does?

Have you actually tested the speed? It may just not be showing the proper icon.
Either way, putting a different rom on it should do nothing to effect your carrier, aside from included APN's.

Do you get the refarmed 1900 Mhz 3G/H+ in your area?I believe the HSPA+ in my city is the non refarmed version, therefore Edge is the best I get, even after enabling network settings in build.prop (thanks! @id10terrordfw), and after playing around in the service menu. I can get it to connect to HSPA+ on a competitors' network (local carrier called West Central Wireless), and it shows the 4G icon in the top corner, but their network is either a joke (which I have a feeling is the case), or throttle the heck out of competitors' phones connecting to their network. Either way, I simply suspect that this phone just simply doesn't have the band that T-Mobile needs to get fast HSPA+ (or non-LTE 4G, as I like to call it).
I can go into my local T-Mobile store and run speed tests on their Nexus 4 and GS3 at any time and get around 12Mbps. Their GS3 shows 4G (which I know is not the LTE 4G, and their Nexus 4 shows H+).
I've read from various forums members that flashing the Nexus 4 modem is a no-no, but I don't understand that if this hardware is identical to a Nexus 4, why can't we enable/flash support for the band we need. I haven't been out of town to a market that has true T-Mobile LTE to test it, but @STravers says it works, so I don't see any reason not to believe it.
I have noticed on the stock rom, 4.1.2 I get mostly LTE and 4g and rarely edge. I have also noticed on aftermarket ROMs the signal bounces around a lot. I'm currently running CM 11 p11, is there any way to get better signal? Or force it to only get 4g and LTE? I have already gone into settings and chose T-Mobile fast APN. What else can I do. Thanks

I'm guessing you were on att stock and liked the signal. Then you flashed a tmobile rom and now signal is different no? If you liked the att stock rom signal, then the modem or "Baseband version" you liked is the "I717UCMB4". If you check under "About Device" it will tell you what baseband version you're on. You can flash modems separately and find out which one works best for you. Just do a search for modems!
