Making "LTE" Work - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I have flashed many different roms trying many different APN configurations, and found out the only way to get true "LTE" speed. Is to stop at the carrier (AT&T) and have them put you on the "LTE" network. Without this no way to recieve "LTE" speed. You can also call them & tell them you have a new phone and give them the IMEI number. No need for different sims just do there thing. No added cost to plan, just them changing you in the system. And hold on because this thing is Faaaaaaaast!!:

Yes...you need to subscribe to LTE network with your provider since LTE runs on different bands than your regular GSM bands.

Yes u have to have them add lte to your plan. I believe this was discussed in depth a dozen times

You do this only one time rite? After flashing t989 roms you can just enable LTE by editing APN.

lte
Never got it to work on My tmoble roms

I have gotten about 24mbps max with t989 roms i think.

Someone clear me on this.
So if you get a ATT skyrocket, on LTE network.
And you flash it w a Tmobile based ROM you lose LTE connectivity?
I'm curious because, even w a custom ROM i go to about phone shows having LTE network connectivity

Do a speed test, I would say if you got it to work in you got the lte icon your speed is way better you probably got it. I didn't have any luck but that was before I went to at&t and had them change my plan. since then I haven't tried a t mobile rom.

Changing Rom, slow radio

Hi everyone,
When I change my rom from AT&T to any other rom, ( ICS ) my phone takes forever to switch to LTE. from HSPA
When I loose LTE single and it goes back to HSPA then it takes for ever to switch back. I live in the DC area in a strong lte area.
When I re installed the stock rom from AT&T tar file it doesn't take any time to switch over.
I have tried all the radios from ATT to Rogers radios and nothing, all of them are slow to switch.
I don't mind the stock rom from AT&T but next month I am going oversea for a few weeks and I want to buy a sims card there.
I am going to buy the unlock code for my phone. Will it switch over or do I need to change the radio to and unlocked on from Rogers. If I change the radio now I am afraid of the same problem above.
Thanks for any help

[Q] How to get 3G/4G with unlocked Blaze on AT&T

I bought one of these phones, rooted it, unlocked it, and installed CM9. I love the phone and OS, but I cannot get the 3G/4G to work on AT&T. Any ideas?
Yeah. The data network is incompatible. Different frequency.
Sent from my SGH-T769 using xda premium
Yeah I think all you can get is 2G (edge) on AT&T with the blaze.
I can say from first hand experience that the blaze works great with AT&T's 3g service. I bought this phone last week, unlocked it, and swapped in the sim from my old Aria and have been using it with CM10 ever since. Data speeds are around 3 to 6 Mb/s down and 1 Mb/s up, and voice and text messaging works fine.
For a more technical answer, AT&T uses the 850 mhz and 1900 mhz frequencies for UMTS (3g), and T-mobile uses 1700 mhz and 2100 mhz frequencies. The blaze supports UMTS on all of these frequencies so there are no technical roadblocks to using this phone with AT&T. http://www.phonearena.com/phones/Samsung-Galaxy-S-Blaze-4G_id6824
As for your problem of not getting 3g working, I had similar issues when first switching the sim card (especially on the stock rom). Check that your APN matches the one your old phone was using. On the stock rom, the phone did not auto detect the correct APN and this caused the 3g to not work. CM10 detected the correct APN right away though. Also, try turning data off and on or even rebooting the phone once you've checked your network settings.
I sold my other phone and no longer have it. Please confirm your APN settings, and how do I change them?
The blaze has all the frequencies necessary for it to do HSPA (3G/4G) on AT&T's networks.
You'll likely want to change the APN. On CM9/10, go to Settings -> Wireless & Networks + More... -> Mobile Network Settings -> Access Point Names.
I was careful in selecting this specific phone because of its compatibility with AT&T HSPA bands. I have tried the suggested tweaks to the APN settings within both CM9 and CM10, but I still get no visual notification that the phone is operating in 3G or 4G mode. The areas in which I have used the phone consistently provided 3G and/or 4G coverage consistently with my prior BlackBerry 9860.
Any additional tips/tricks would certainly be appreciated. I know this phone is capable of so much more than it's providing me at this point.

have you tried running a speed test to see if maybe it's just that the icon isn't coming up?
That is why it was called the "Merger Proof Phone"

[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

Verizon M8 on At&t/Cricket

I have rooted and s-off. Used the guide to enable additional bands. I used NV values 65626 and could get LTE in some areas but not in others. I'm starting to think it's radio related. Any suggestions?

what bands, specifically, did you enable?
Bands 2, 4, 5 and 17. I'm located in the Raleigh Durham area of NC. When it was connected to LTE I used the LTE discovery app and confirmed the uplink and downlink freqs. 1900/2100 if memory serves me correctly.
Currently using the VZW M8 on Cricket. I'm getting HSDPA but no LTE.
But I have no complaints. Phone is awesome and mobile data is working flawlessly.
Yes it's radio related. Verizon and ATT do not use all the same frequencies and bands.

Hi,
I tried to read any info about it. But I don't know....
Here is my theory: The Google Play edition (GPe) is open to any LTE channels. I know that you can turn the verizon M8 into GPe M8... (I don't know if the phone can operate on Verizon after all :S )
So hopefully that can work, but I NEVER TRIED IT!
So If some GURU can help us that would be grate. And also a "How to" -from the very beginning ( Stock rom, s-on, non rooted, etc) would be nice too.
Thank you
Ps.: I was only modifying Samsung, Sony, Motorola, Zte before. This HTC "magic" is totally new for me

I am in Virginia. Right now using a stock Verizon M8 and I do get AT&T LTE signal( download speed is around 10M, upload is 7M. Phone info said the network is LTE).
I guess my area using band 4 for AT&T LTE.
I am considering enable band 17. If you are available, maybe you should share some thoughts of your Band-unlockin process and your LTE signal situation.
Thank you.

Very competitive Verizon MVNOs are starting to emerge, have you compared coverage in your area? I'm on ROK Mobile and it's freaking awesome.

Most of the ATT guys are clueless, not matter they are in store or over the phone. Just ignore them.
All you need is get an att nano sim card, put it in your verizon m8. Boom! You could text and call now!
And then you need to edit APN settings to get data working. Go to settings, Mobile data, Network settings, GCM/UMTS Options, Access point names, and add a new APN:
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http://mmsc.mobile.att.net
MMS proxy proxy.mobile.att.net
MMS port 80
MCC 310
MNC 410
Authentication Type None
APN type default,mms,supl,hipri
APN protocol IPv4
Bearer Unspecified
save this APN and select it to use. Wait 30 sec to 1 minutes, Boom, you would have H+ or 4G LTE depending your location. For most area you would get H+.
You don't even need to root !
im on edge slow slow slow
I get HSPA+ on my stock M8. My APN is "phone"
I have GoPhone account with AT&T and I get LTE in some areas, nothing done to my phone, stock Verizon m8, apn set to nxtgenphone , I get HSPA most of the time, but I do get LTE in some locations here

So happy to see that you are replying back to me after two years.

T-Mobile LTE in US isn't working...ideas?

I imported the 8141 from Clove in the UK. So far, my only real issue is I have yet to see it connect to LTE. I've seen "4G" and "4G+", but no LTE...which is a problem because I can barely pick up a signal other than LTE in my area. I checked and confirmed it's using the correct APN (fast.t-mobile.com). I'm on the 110/unlimited/unlimited $30/month prepaid plan and confirmed I haven't hit the LTE cap. If I put the SIM back in my Moto X Pure/Play, it hops on LTE without a problem.
Everything I've read says the radio should support T-Mobile's frequencies. Is there another setting somewhere I need to change? Do I need to flash another region's stock ROM (and is that even possible yet)? Did I get a lemon? Do I need to hold it a certain way like whatever iPhone it was a couple years back?
Any and all suggestions are welcome.
4G+ is the UK's LTE as far as iconography is concerned. Have you done a speediest on 4G+?
I've noticed the same thing, but I (as mentioned above) thought that LTE and 4G+ were synonymous. I think the only reason to flash a region based image would be to enable radio bands that are disabled based on location (which may be in this case).
Works fine here. Lower Manhattan using same version.
4G is LTE in US.
Download LTE Discovery and you'll be able to see if it is connected to LTE or HSPA(+). Mine, also from Clove, is just fine with AT&T LTE.

4G is basically the same thing as LTE in this case. 4G includes WiMax and LTE. So when you see "4G" it means you're using LTE. The same goes with 4G+ - LTE-Advanced (LTE+).
I have LTE logo on my Z3 while Z5 Premium shows 4G while using the same network.
4G is LTE in europe. We did not have that silliness that some 3,5G was called 4g. Also there is no band limitations on XZ Premium.
For app to check which band of spectrum you are connected to, please use Cellmapper app (from my signature).
If you wish to see different icon in there, you could flash Customized DE firmware which has "LTE" icon. But this has only cosmetic effect.
Instead of making a new thread, anyone knows if VoLTE works with the XZ Premium for T-Mobile?
Currently no. You need region or operator specific image Flashed (oem.sin) but there is none for XZ Premium.
But there is hope as there is t-mobile us specific modem configuration in all region images.. which will be loaded when you have correct oem image Flashed.
