No 4G on CM10.1 Straight Talk AT&T - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I have my APN settings all set up. I am in a 4G area. I was getting 4G prior to flashing CM. I'm now only getting 3G. Any suggestions?

Do you have the right network type set?

Does Straight Talk even support LTE? 4G on CM roms is LTE but 4G on stock AT&T roms is H+.

Straight Talk does support 4G (HSPA+) but does not support LTE. I was on the stock out of the box rom and I was getting 4G so I believe that 4G is HSPA and LTE is of course 4G LTE. Anyways the link from the previous posts claims in 4.2 that the data connection is slowed down when in idle but when strain is used on mobile data, the phone will automatically bump up to 4G (HSPA) , I am in 4G area.

On ANY AOSP ROMs, 4G is LTE. If you are on HSPA+ it will show HSPA+. Phone companies showing that their HSPA+ is 4G on stock ROMs is a lie. So, if it shows HSPA+ as your connection, then you are getting what phone companies call "4G." Thanks.

HSPA on Strait Talk
I also have Strait Talk and can say that HSPA/HSPA+ has not worked for me on CM10.1 however it was working on CM10 on a AT&T GS3, and it works on my Wife's GS2 Skyrocket(Stock).

Same here. No issues whatsoever under CM10.0 - was consistently getting H+ (which was fine for me). Upgraded to CM10.1 today and can't get anything better than 3G.
If I do need to flash a new modem, can someone suggest a link or other reference. Looked around all afternoon but couldn't find anything helpful.

Telus: 4G LTE turned into H+ ?

When I first got my galaxy s3, telus said it would come with 4g lte. It worked well and on the top notification section, it specifically said, 4g lte. Now I'm trying out custom roms and such, and I downloaded CM10. However, on CM10, the icon no longer says 4g lte, but it says H+. When I revert back to my old rom, it says 4G (ONLY 4G, no LTE at the end). Can anyone tell me why my data connection has been demoted, or if it has been demoted at all? Should I just give Telus a call and ask whats up with this?
And yes, LTE is available in my area, I'm in Vancouver.
Thanks

I have the same problem: I have ATT, since using custom ROM (TASK ROM) i have lost LTE, even though the APN settings are correct, the only way that i've have gotten LTE back is by going to the store and getting a NEW micro-SIM , then LTE works, and to answer your question, H+ is just HSDPA+ and 4G is LTE.

And just for clarification: when you got the new micro sim, were you able to combine both the custom rom and 4g lte? Or is it one or the other?
yeah apparently in canadian carriers, they're changing up things, like for example our rom on ics, i get 4g and LTE even tho im on 4g plan but s3 is LTE but some custom roms such as cm9,10,miui,aokp and so forth have things setup to h+ and for example even tho you might LTE speeds on cm10 via toggle of LTE on, it'll still show 4g meaning it is LTE but its just how structure in systemui is setup. eventually we all hope it'll change, best way to find your speeds and confirm what you're getting is Speed test via market and it'll tell u all.. hope it all helps
edit and it'll also depend which towers are setup in which configuration, such as if you're closer to main junction of cities for example Toronto for me, i'll get LTE like whoa but say im in brampton now it might have towers catching LTE but not as frequent hence it'll fallback on 4g.
AOSP ROMs will always be G, E, 3G, H, H+, 4G
G - GPRS
E - Edge
3G - 3G
H - 3.5G down
H+ - 3.5 G up/down
4G - LTE

yeah like as i was saying structure is based upon that. the reason why those structures don't change is because vanilla roms aka aosp roms are not just based on 1 type of device but 1000 of devices so you can imagine, doing 1,000 different things, ahh id go nuts haha

Well it's just a more accurate representation of what you are connected to... Despite what all the carriers say, the stock rom only saying 4g, is NOT 4g... it's 3.5g which is better represented with H, and H+.... Marketing schemes really... True 4G is LTE...

yes sir, true it is marketing schemes haha i didn't wanna say it out loud but hey sometimes you gotta do those things to sell =) right ,as carrier perspective if they can sell all the stock for the devices and make the money they're happy, and we're happy lol.
I've noticed with my device that LTE coverage, at least in my local area, is fairly sparse, but occasionally present nevertheless.
If you're not seeing it at all, you might check that LTE is enabled in two places: check Settings -> More -> Mobile Networks -> Network Mode for an LTE setting; and dial *#*#4636#*#* to pull up the Testing menu, go to Phone Information, and check "Set Preferred Network Type" for an LTE setting. Doing both of these allowed my phone to start seeing the LTE network.

Testing Tmobile with unlocked S3

Hey All,
I've placed a Tmobile sim in my Att unlocked GS3. Ive seen many posts stating that the Att version wont get 4g on tmobile but 4g works fine for me; regularly I can get 5 to 10mb downloads. My issue though is that Im sometimes dropping from 4g to 2g/Edge then back to 4g. Should my phone be dropping to 3g instead ? Im quite shocked when it happens since I usually had strong 4g not far away at all.
Is the general consensus to to simply get a Tmobile device instead of bringing something from at&t? I really dont want to root the phone or flash roms at this point since Im just testing out the service.

You are in a refarmed market from the sound of it. The reason you go from 4g to EDGE is because the refarmed spectrum is most likely not through your entire coverage area.
T-Mobile uses the 1700 band, which at&t does not support, as their primary 4G deployment. This is why it is always recommended to get a T-Mobile S3.
That said, there is a firmware image for at&t's GS3 that unlocks T-Mobiles AWS band not just for 4G but for LTE as well. It is in the at&t forum - you will have to read the entire thread to get the relevant files and information on how to do it. Note that this CAN brick your phone permanently so only attempt it if you are willing to take that chance and you are familiar with download mode and ODIN.
The upside of using that hack is that the T-Mobile S3 doesn't support LTE at all.

Thanks for the clarification and info about the hack. Assuming I get a Tmobile device, should I expect to see a 3g icon instead or would it still say 4g?

It'll say 4g.. A 4g icon really means 3g/h+ and a 4g lte icon means lte

[Q] Galaxy s3 att unlocked.. All ROM show 3G

Hi i have Galaxy s3 ATT i747 unlocked and every ROM i install give me 3G.. If i leave stock ROM it gives me 4G with know problems.. Is there any fix i can do that will give me 4G and modem i can install. Im on tmobile network
Can you see your IMEI number? I lost mine while flashing roms and the network couldn't recognize my phone, so it booted me down to 3g (but I'm on ATT).

Do your roms have the correct apn's?
I'm having connectivity challenges when trying 4.2.2 roms on Rogers w/ my i747m.
Tried most of the recommended modems on for i747m (complete modem list) http://forum.xda-developers.com/showthread.php?t=1831898
with CM10.1 and AOKP Task650.
The result, at worst little to no connectivity, at best intermittent connectivity. It doesn't seem to want to switch between towers and getting connectivity better than gprs or edge is pretty much non-existent
When I burn the rooted Rogers ROM - root66_RWC_I747MVLDLK4.tar.md5 I get good connectivity switching and 3G. I haven't seen LTE yet but it was only officially rolled out here 9 days ago so it's still crap and only partially out.
I'm about to roll back to the rooted ROM and apply the latest Canadian patch via KIES and give up on S3 mods. If some kind canadian has the time or inclination a faq/step by step on a S3 rogers install that actually works would be very appreciated. I've tried most of the recipes on XDA, task650, cyanomodgen and can't seem to come up with a working combination that gives me data/phone service that is at least as good as stock.
thanks,

This may be correct. Do other ROMs switch between 3G and H+? Do you see 4G vice 4G LTE on stock rom? What download speeds are you getting on stock and other ROMs? With AT&T, HSPA was labeled 4G instead of H or H+. They had to add LTE to the 4G after LTE went online for them in order to differentiate a difference. The majority of places have HSPA labeled as H or H+ and LTE is considered true 4G. I have noticed that many ROMs will show 3G until data is received/sent and it switches to H+.

How do I re-enable LTE

Hey all! Ok, so my gf has had this S2 from Koodo (Telus) since January. Out of the box it came with LTE/4G enabled and working fine. However, I rarely leave things alone and right away I installed TWRP, AOKP and I think, Tiberius Kernel. Have been using variations of each since. However, ever since I did that, the 4G hasn't worked. In the phone settings it says LTE/GSM Auto. However if I change it to anything else, like LTE ONLY, for example, it just stays at LTE/GSM auto. Nothing happens. So I am wondering how to get her 4G to work again since I know it is fully capable of it and my area does have working LTE.

4g is the same as H+ on custom roms. And now some say DC. Not sure why they left behind the 4g symbol, but its all the same thing. So if you see H+, DC or 4g, its all actually 4g.
You should be on GSM/wcdma preferred in mobile settings.

It instead says 3G. Before rooting it said 4G above the signal bars. Every once in a while it says DC. Any advice?

Explained the symbols in posts above. And if you are getting a lot of 3g....that's reception. Your losing your 4g connection and its picking up 3g. Usually for this to happen you'd only be getting about 1 bar on your signal.

I appreciate the info. I live in Orlando and I'm pretty sure we have tmobiles 4g or hspa+. I was just wondering why I'm only getting 3G date speeds instead of 4G speeds. The internet still seems relatively fast but wanted to make sure the phone wasn't slowing down the speeds to 3G speeds.

Aosp ROMs run on 3g (umts) until data is called. Once data is called it will pull up h+(hspa+)or dc(dc-hspa) depending on your area. Its a battery saving feature and the stock Samsung ROMs show 4g all the time. Unless on edge or GPRS. I think even touchwiz ROMs went to umts while idle.

Need help on LTE problem with liquidsmooth 4.4.4

So I flashed this rom yesterday on my t889 4.3 http://forum.xda-developers.com/showthread.php?t=2724553
Its been working great and I really love it but there's one thing that I'm having problem with. On the data option you can only pick LTE, 3g,and 2g. I actually need an option like LTE/4g because I live in Corpus Christi Texas where LTE is ON and OFF on T-mobile (You get LTE sometimes but sometimes you only get 4g) and what this rom does is, it only search for an LTE network. And since the LTE network in here is on and off meaning it switches to 4G only and that makes my phone unable to connect to the internet.
Is there any fix to this? Or is there any 4.4.4 rom that has this option? I hope I explained my problem well and I'm sorry I can't post on the liquidsmooth thread because It won't let me cause I need more post count. Any help would be greatly appreciated!

On AOSP based ROMs the network modes are reported by what technology they are using. LTE is reported usually as LTE or 4G. TMO "4g" is UMTS, HSPA, HSPA+, etc and are more like 3 to 3.5g. Tmo "4g" is mostly a marketing gimmick that blends 3g tech and relative 4g speed (with the downside of terrible latency at times).
Choose the 4,3,2g option, the phone will try to get you the most effective connection available.
Don't be discouraged if you end up sitting in UMTS/3g for the most part, the device can shift into "4g"/HSPA+ nearly instantaneously.
