[Q] Which radio for T-Mobile LTE? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I have an unlocked Samsung Galaxy S2 Skyrocket, and I have just been getting 3G and H+ where I live (Arkansas) and we just got LTE in our area. And I was wondering what radio I should use, or if I do need one because it has not shown LTE up in the Signal Icon. I'm currently running the T989UVMC6 Radio. I've also tried going into Mobile Network Settings and changing it from GSM/WCDMA Preffered to LTE/GSM/WCDMA and also changing the access point name from the T-Mobile-US one to T-Mobile-US LTE. So if you could help me out with that it'd be great. Thanks!

I was able to get LTE on T-Mobile using the UCMC1 and UXUMA7 radios for Jelly Bean. I am running Embryo 6.11 JB custom ROM. Flashing the regular T-Mobile radios only allowed me to get HSPA/HSPA+ in LTE areas.

Force LTE to Edge/3G

Hey! I'm new to the forums and just got a Skyrocket this week.
I was just wondering if its possible to force the LTE signal to HSPA only or even Edge/3g?
Looks like the LTE radio is locked pretty tight. Anyone out there find a method to bypass this? I've tried the administrative menus in the Phone Information menu and even some of the Apps in the market LTE on/off and nothing seems to work.
Thanks!
Pretty sure you can change your APN settings to allow only hspa since lte seems to require the PTA setting. Look for the various settings and I'll update later if you have no luck.

I thought of that too for battery saving.
Here in Canada I tried changing the APN from the default LTE setting to the internet.com setting but it is still stuck on 4G. I didn't subscribe to LTE plan yet but Speedtest.net tests is still better on the LTE apn.
*#2263#* gives access to the RAT selection menu, which lets you choose to park on GSM/UMTS/LTE, and separately which bands (850,1900,1700,2100, etc.) to park on within each technology.
Unfortunately the menu is restricted on our current radio, in my experience with previous Samsung UMTS radios we will need to flash a radio that is not restricted (at least temporarily, to unlock the menu) to get access to this.
@cue_32 i believe its supposed to say LTE when you are on lte. if it says 4g its really just 3g (or 3g+).
It would be great if an LTE on/off switch was created. If the current radio restricts this from occurring would be a huge bummer. I'll have to dig around on the Development blog to see if anyone is starting to look into this or creating some kinda switch.
The TPC rom gives you the option to choose LTE or HSPA in the settings.

What would be nice is if the ROM only connects to 3G when on idle, then go to 4G or LTE when data is being used. For better battery life

Hi, how can I bypass AT&T throttling through chaning the APN? I'm running 2.3.6 stock and am in NYC. Thank you!

Force 2g. Is it possible and how

Most of the reason I rooted my phone was to be able to force my at&t Skyrocket into 2g mode. I get little to no 3g coverage at work and when the phone switches to edge (2g) I get almost full bars. I have tried cm9 rom which has a known issue with forcing 2g anyway but gave it a shot. I also had aokp with no luck. And yes, I went to settings>network>use 2g mode on both roms. Then I went after radios......I know at&t has a rat locked radio so I thought I'd be clever and try the rogers rat unlocked radio. Got really good data speed, call quality, and signal other than work of course. But still didn't allow the force 2g mode. Tried the *#2263# or whatever and it won't even bring up a menu on at&t phones which is understandable because its a rogers thing. Then I tried the trusty ol *#*#4636#*#*. Wouldn't do anything either. Suggestions anyone? Or maybe its just impossible....

You can force the Skyrocket into GSM-only (2G/EDGE), but your ROM has to support it. Sky ICS does, not sure about others.
*Edit: Just tried it on my phone, and it seems to have worked fine.

You can on cm9 by first going to "select network operator" and choosing at&t. Then 2g networks only will stick. Thank cschmitt for this.

Greeting from Hong Kong.
I encounter the same problem. The 3G (WCDMA2100) signal at my home is too low (<-110dbm) to make a call but my Skrocket could not switch to the 2G network (GSM900 with -85dbm) automatically. I wonder if anyone has an apps that could switch the phone to 2G mode through the servicemode menu (*#2263#, 3, 6) and then back to 3G mode (*#2263#, 2, 6).
Bender mentioned that a Sky ICS ROM could do it. Please let me know where I can obtain this ICS. Thanks very much.

I was wanting to do this without flashing a rom. I am running stock ICS AT&T i727UCLF6.
I have the same problem where i don't get very good 3g service, drop calls all the time and would just like to force it into 2g mode while at work. Why would this be removed from the rom should be a basic feature.
Install RAT unlocked modem, *#2263# and picking specific band that is supported by your provider suppose to work. Tho it's not gonna work on CM/AOSP based roms. It will work on att phones.

Thanks very much. Flashed the Rogers Offical ICS modem found here. [MODEM]Official Rodgers..Release Modem- UXLF3
I am able to change to 2g mode only now. However i was wondering if there is a possibility of automating the process via an app, instead of using the *#2263# via the dialer?
For G only: *#2263#, choose option 3 GSM band preference, Then GSM 1900 I did not get 2g on this option but I hear from others that you can.
For 2g only: *#2263#, choose option 3 GSM band preference, Then GSM 850 Never dropped to G but has the possibility to.
For 3g/HSPA only: *#2263#, choose option 2 WCDMA band preference, Then WCDMA 1900 or 850
To return to normal: *#2263#, Choose Automatic.
I don't have LTE in my area but I believe you can choose LTE B17 from LTE option to have LTE only. Didn't buy for LTE but because it was the best device (specs) through AT&T at the time.

Sure you can get LTE/HSPA+/HSPA/3G(UMTS)/EDGE with that depends on how strong the T-Mobile signal is at your location.
Yeah. I tried everything but no luck. My cousin had lte on his iPhone at my house. My s1 have 3g/h on it running 1900 mhz. I'm stuck on 2g or just no signal at all

Does it stay on the Network type when you change it? Is 'use only '2G networks' option enabled on your Mobile network settings?
Try to flash to another RADIO and flash back to UCMC1 on CWM. If it still doesn't work, flash to stock AT&T ROM and make sure you can get other than EDGE speed and then flash CM 10.1.
Good luck.
Thank you. I'll Do As you say Tommorow. Eariler when i flashed 10.1 on this phone i had 3g/hspa but after half day i got pushed back to edge. After that i never got 3g/hspa. I have to check the 2g Networks only if i don't my phone won't get any signal.

That explains why you get EDGE 2 because of that. I suggest you to diable 'use only '2G networks' option and to flash [RADIO][UXUMA7] For I727/I727R on CWM to see if can get HSPA+/3G first after that.

Yea, looks like CM 10.1 should be nearing a stable release soon so I'll root it then. I'm coming from a HTC Glacier since the devs decided to stop supporting it.
One thing's for sure though, LTE tends to burn through my battery. I hope it gets better once it's rooted.

I am running Embryo 6.11 (JB 4.1.2) ROM using T-Mobile's SIM, and was able to get LTE using both the UCMC1 and UXUMA7 radios. However, the phone defaults to EDGE when outside of the LTE area, instead of switching to HSPA+/HSPA 3G. Using *#*#4636#*#*, my network selector is set to LTE/WCDMA/GSM. I would have to manually set it to WCDMA only to pick up HSPA+/HSPA. Then when I toggle back to LTE/WCDMA/GSM, the radio picks up HSPA+/HSPA. Hope this helps!

[Q] 4G LTE/HSPA+ on Net10 with Skyrocket

Okay, so heres the deal. I currently have a Skyrocket running CM 10.1 with the UVMC6 radio on Net10 T-Mobile SIM. I my home town of West Bend, WI I get H+ and decent speeds of about 6Mbps down. When I'm in Milwaukee, WI I occasionally get "DC" (Dual Carrier?) with some pretty impressive downspeeds of 20Mbps. I have LTE enabled on my phone but I have never gotten a 4G or LTE indication when in Milwaukee. Which I believe is a T-Mobile LTE area. So my question is if I switch to AT&T SIM on Net10, will I get 4G LTE speeds? It is not specifically indicated on Net10's site that I will, but they sell LTE phones.
Thanks!
It all depends on what net 10 (or whatever) are providing...I doubt those MVNO networks offer LTE from the patent networks at this moment, though I might be mistaken...That 20 mbps you get is HSPA+(DC is HSPA+21 x 2 = HSPA+42)...They sell LTE phones doesn't mean anything, most modern phones nowadays are LTE phones....
However, if you join T-Mobile(T-Mobile proper that is ) and in an area which is one of the official LTE launch cities, you can connect to it using the stock SR radio...

Thanks! I was wondering how I could be getting speeds that fast without LTE. Also, is HSPA+ is rated for 42Mbps then how fast is LTE rated for and is the 20Mbps down that I am getting relatively high for cellular speeds these days?
It depends on tons of factors...HSPA+ at 20mbps is faster than the LTE I get....The only real plus to the LTE is the excellent low ping latency...

You shouldn't trust any people or site more than what your carrier tells you. If I were you I would've just called / emailed net ten and asked them directly :good:

They have tried telling me that my phone is incapable of mms when i was having problems with the stock apn they provided. I wouldnt trust any infomation they tell you.
Those MVNO networks and their customer rep suck big time to be helpful at all....
I use my Skyrocket on Net10 AT&T SIM and the best I have ever gotten is HSPA+ 21.6 even in an LTE area... Net10 SIMs don't allow connecting to LTE networks.

If the frequencies are the same as Rogers / AT&T then there's no reason for you to not have it. Try doing more troubleshooting.

That's what I figured, I mean it's an ATT phone after-all so if should work with their LTE. But after some troubleshooting I discovered that my phone will not enable LTE for whatever reason. I will go into the settings menu and select GSM/WCDMA/LTE and it just auto switches back to GSM/WCDMA preferred. I am currently running CM 10.1.3 RC2 with UCMC1 radio, so I will try re-flashing that radio to see if it helps, but I don't know what else would cause this.

Try Rogers RUXUMA7 radio, I think that the UCMC1 radio has some kind of lock which prevents you from switching modes.

Rogers radio is working better at keeping lte enabled for me. I am on an older net10 sim and after calling customer service they updated my account and its working although my lte ping times are very similar to hspa... I'm on slim 4.3 build 1

I have the exact same problem. 20 minutes on the phone with Net10 today and they said I would have to contact the manufacture(Samsung) to get LTE. Made no sense.
Go to network operator, scan and pick att from the list. Then try changing the mode to lte/gsm/wcdma and it should stick. Was happening to me too but this fixed it

Skyrocket GSM Network Signal

I got an AT&T skyrocket SGH-1727 from my brother from the states. I am currently in the Philippines.
I unlocked the phone and flashed the latest JB radio rom and CM 10.2 stable rom. The problem is I do not get GSM/2G signal. My phone can connect to 3G and LTE but in areas were there are no 3G and LTE outside of the city, my phone just couldn't connect to 2G. I tried several radios like UXMA7 for Rogers skyrocket and even the TMobile UVMC6 T989 radio. I feven experimented with several roms and went back to stock but the scenario is still the same.
Is this because the phone is not compatible to the 2G frequencies in the Philippines which is 900 and 1800?
Is there a workaround to this?
Regards.
