[Q] Can't get LTE on Tmobile. Any solutions? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Was hoping for some help on getting LTE on Tmob.
Running Cyanogenmod 10.1.2.
Using fast.t-mobile.com APN
Have tried the following radios:
UCMC1
UXUMA7
MUGMC5
MUGLH2
MUGLCA
The phone is registered on Edge. It will pick up the LTE signal, and will show 4g for about 5 seconds with 4 bars of signal, then 4g with 3 bars of signal for another 20 seconds. After that it will go back to Edge. While it shows 4g, in the status menu/mobile network type it says "LTE:13". When it is briefly connected to LTE I get no data.
I'm at a loss. It seems to connect to the network but will not stay connected. Has anyone else had this problem? Any solutions? Called T-mobile and they were of no assistance.

BUMP!! would love an answer or a link if this exist already.

Im in the exact same boat. The Tmobile people said that the signals run on different bands, and therefore ATT phones won't always pick the best LTE signals as a result.

Hey, so there's definitely a thread on this lol. Also I'm on tmobile & I can confirm that LTE works. I'm on UCMC1 and it's works on every ATT ROM or stock based ROM I've thrown at it. By setting the fast APN. Check my pic attached.
You know if LTE is available where you are?

[Q] Can i get 4G

I have a rooted samsung Fascinate. I want to know if there is any app or anything that I can do to get it to recieve 4g from verizion. Any suggestions are greatly appreciated. I only ask because my town has 4g, but I only ever have 1-2 bars of 3g data service at any time. So if anybody knows if I can get 4g, or any way to get a better 3g signal.
Addt info: It is not any problem with my phone, most people in my town have terrible verizon 3g ever since they added 4g
nope its a radio and internal drivers thing.
No, Verizon 4G or LTE requires completely different hardware for the radio inside. The reason your service is suffering from the advent of 4G is due to Verizon converting existing 3G sites to 4G.
When this is done, 3G signal will depricate as there will be less 3G radios serving your zone.

Verizon 4G LTE Not Working..

I just got 4G LTE turned on in my area and I can't seem to get 4G to toggle on.. It's only showing a 3G signal. I tried using a 4G toggle app using device info to change it to LTE only, but no dice. I'm sitting next to my friend with a 4G signal, so I know it should work. Can anyone offer any assistance?
Sent from my SCH-I535 using xda app-developers app
Pretty much in the same situation here except my area has had 4G for months now. I've personally tested a Razr and a Bionic in multiple locations nearby with fantastic speeds and was pretty excited to have LTE on my new phone but haven't been able to hold onto a 4G signal for more than a minute or two.
Since this is my first 4G phone it's been recommended that I call Verizon and make sure my account is setup correctly for it. If that doesn't work, the main Verizon store in my area has full LTE coverage so I'll bring it there this weekend and try to swap out with a new phone.

[Q] WIlling to buy a friends´s Blaze for cheap. How can I get 3G using At&t?

Hello, a friend of mine of selling a mint Blaze at a great price. Phone is unlocked and I have service with At&t. However, when I insert the sim only get Edge. Is there any way to flash At&t radios to the blaze? I did search before opening a new thread,,, but wasn´t able to get the info I need.
Any help would be very appreciated!
Thanks!
Nope...edge only

Are you sure? my wife uses the Tmobile s3 with Att and gets 3g. could be this phone runs different frequency's?

He's wrong. It'll run on their H+ network, but that's all. However ATT's H+ mind you is very congested in a lot of places (NYC especially), but it will run.

Should be able to get hspa+ flash a at&t skyrocket radio fix your apn,
I know it works when using T-Mobile on at&t phones I just flashed T-Mobile radios fixed apn got hspa+ speeds, should work vice versa
Edit: heres some at&t radio's that can be flashed http://forum.xda-developers.com/showthread.php?t=2270071
I have a Blaze running on NET10 using the AT&T sim card. I can achieve H+ with it, and from time to time it shows me 3G then goes to H+ real quick.
I am able to get (depending on where I am here in Central Indiana) 1-2Mbps with H+ and in other areas I get 12Mbps with H+. Here at the house I show H+ with 3 bars right now and get 1.75Mbps down and 0.42Mbps with a ping of 148ms to a speed test site just 16 miles up the road.
I do have to say it is much better then Tmobile here, I was lucky to get 0.17kbps either way on Edge.
I can tell you that it will help you if you go into your settings and select mobile networks then mobile operators and set yourself to AT&T Network only, let me know if this helps any, it did for me. It has kept me from trying to hit Tmobile towers since I am on NET10 which uses both tmobile and att.

Skyrocket i727 with Tmobile at LTE/4G Speeds

Guys,
I just noticed my SGII gets LTE Mobile network type at work today. Below is my what I have.
Unlocked ATT Skyrocket i727
[ROM][OFFICIAL][CyanogenMod 10.1 Nightlies for Skyrocket] Build 0609
RADIO UCMC1
You don't need expensive TMobile iPhone 5 to get LTE speed.
Good luck and have fun!!

Dallas Campbell, TX I think T-Mobile just have their network re-farm done here recently.
See HERE for the re-farm map.
Thank you. I live in Lewisville but my cousin told me all the Carlton area he was getting LTE. Do you also get 3g or HSPA+ because on mine i get 3g for sometime then i have no signal at all. i have click on 2g network only to get signal. Also which APN are you using?

Thank you. And one more question if i do this
You can use *#*#4636#*#* to change your preferred network type. I am using LTE/GSM auto (PRL)
Will i get both lte and 3g/hspa because i'm stuck at Edge but i know my area have good service. Because on my mom's iphone 3g it does have 3g signal it uses 1900 mhz
There messing with the 4g as I type this in warren/Detroit Michigan not yet strong enough to get a speed test. will update
Edit: here's lte

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.
Still stuck on Edge. I tried *#*#4636#*#* method but still no luck.

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.
Did you get better reception when you flashed the i757m radio?

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...
To know the type of network you're connected to, go to settings/About device(or phone)/Status

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:

hahahaha....if you know how to turn your phone on by yourself than you know more than the customer service people at net10/straight talk. They only know how to read off their script cards. 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.

Well I don't know what happened, but it just out of the blue started showing 4G and LTE. So now it works and I'm getting 25Mbps down!
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
