For some weird reason, ever since i got my GS3, i lost LTE. Its odd because i come straight from the skyrocket so i already had the lte data. But since i got the GS3, my phone can only connect to 4G (NO, 4G is not LTE, its H+). So i called rogers tech support, i spent about 4 hours with them, making tests, getting transfered to level 2, then to customer service to make sure i had an lte data plan...finally they told me your phone is broken to get a new one. So i go to rogers, they give me a brand new GS3, same damn thing...only getting 4G. We tried 3 different sim cards, nothing.
Then i call back rogers, they transfer me to the "above level 2" which they told me is the master departement. They guy tells me they will emulate my sim card in their lab with a GS3 they have...but nothing. All settings seemed right, APN and everything was good, so they finally opened a master ticket.
But for some reason, i dont beleive i'll get a call back anytime soon, so anybody might have any suggestions?? I'l fully stock, not yet rooted
Try performing a manual network search, then select Rogers to have it manually "Register" on the network.
For some odd reason, I had the same problem as yours, but after manually registering, LTE was back on, I switched it back to Auto after
check the sim card, there is also a chance that they gave you a 4g sim card and not an LTE one (bell did this to me)
If its LTE then go to the dialer and press *#2263# choose LTE and then LTE all (when you are in an LTE area) when it connects to LTE data do the same thing again but select automatic.

euff yeah, i think i would have checked for the lte sim card in the first place. As i said, we tried 3 different ones.
ill try that thx
Well selecting lte bands manually didnt work.
so then the sim does say LTE on it and not something like 4g? outside of manually selecting and waiting. I'm not sure what else. Maybe try getting them to give you a different sim and test in person. wish i could be of more help.

I already said that when they gave me the phone we tested 3 different sims. Same result. The only way i could isolate the problem is to have a person with a working GS3 on rogers give me their sim
I have never seen LTE when passing through an LTE area. Often I get knocked down to Edge while in Vancouver. No LTE where I live, bus something seems wrong. I was thinking of shutting off the 3g in network settings to see if that helps.
I am new to Rogers and not use to getting bumped down to Edge, as Telus only has a 4G network. Does this happen regularly, or is it a phone issue?
Hello all, so I recently consulted your fine website about purchasing the Optimus G to use on T Mobile here in Pittsburgh. It seemed to me that people were able to get HSPA+21 and LTE on the phone in the right circumstances, and that was good enough for me. So I bought the phone, unlocked it through cellunlocker.com and everything seemed to be going smoothly. I punched in the standard fast.tmobile.com APN address and I got 4G HSPA+ right away. I then proceeded to drive into downtown Pittsburgh, which now has T Mobile LTE, to see if it would connect. It didn't connect and stayed on HSPA. At that point I drove out of the city and went back down to EDGE and my phone no longer connected to HSPA anymore, only EDGE, until I went into my Mobile Network settings and selected the carrier directly. So I went into T Mobile to ask why my phone won't automatically connect to the most OPTIMUM speed and he couldn't figure it out. As a last ditch effort, we switched SIM cards and my phone automically jumped to LTE and his was stuck on HSPA. So hey, we figured it must be the SIM card keeping me from LTE. He gave me a new card, and it was on LTE until I left the store's broadcast radius. From then on, same story. The phone seems to pretty frequently get stuck on EDGE speeds and I contantly have to go and manually set the network to get HSPA+. What's more, I can't seem to get LTE under any circumstances. Can somebody out there please tell me what's going on? Do I have a defective phone with confused radios? Is T Mobile having a hard time syncing with my AT and T device? Do I need to do something with my APN or Mobile Network settings? Does this have anything to do with the way I unlocked the phone? Is it because the LGOG shares radios for LTE and HSPA or something that it won't default to LTE when it's around? I love absolutely everything about this phone and would like to keep it, but if it keeps behaving like this and won't even give me LTE or consistent HSPA+ then I might as well just get a crappy LG Optimus L9 that at least was designed for the network. Any insight you guys can offer would be much appreciated. Thanks so much!
Here are my current APN settings in case that has anything to do with it:

Try flashing the 33-84 radio: http://www.mediafire.com/download/wec8eeext05x8ge/LTEhybrid33-84.zip
That's what I use to flash my LGOG. That's from the Nexus 4 radio thread, and from T-Mobile N4 devices. I was able to add a different APN for AT&T easily, maybe can do the same for your T-Mobile.
- Combines the latest .84 radio from T-Mobile N4 and .33 LTE support.
- The N4 Radio thread: http://forum.xda-developers.com/showthread.php?t=2087227
I see. Well seeing as I'm kind of a noob at this your post intimidates me a bit. How dangerous is it to put these N4 radios onto an LGOG? Will I risk bricking this thing or losing signal forever if I screw it up? Also, I'm assuming that the device must be rooted to do this? Also, if you think it's safe to try is there a thread or something that you can link detailed instructions for? I've never done anything like this in my life...I felt like a rebel just unlocking my phone! Thanks!

Not dangerous if you use TWRP. Just make a backup of your current stuff, and if it doesn't work can just restore. It won't hard brick your phone. And I've had it flash on more than one rom so far.
Root needed?

I see. Will the phone need to be rooted for that app to be used for the radio ROM? That's probably a silly question to ask on this website especially...but there it is.
I just got this phone and I'm loving it..came from the gs3. I was looking for a thread like this...hoping for a way to unlock the aws band..will root and flash tarp and try this tonight.

I don't get lte at all with the FAST apn, I get very fast h+ with epc.tmobile.com. It all depends on your area though, if your tmo towers are refarmed for the correct band that our att phones support.

would like to know if there's any update, thank you!
I have almost exact same problem. T-mobile lte not working for me, always getting the hspa+. I went to store and asked for a replacement sim card, then bang, lte shows up with the new sim card. Right after I walked out of the store and left in about 1 minute it's gone, forever. I'm not able to pick up any lte signal anymore. When I put this sim card in my ogp, it fires up lte right away.
I have read in another post people reporting they get lte with unactivated sim card but it went right away when they activated it. Really hope someone to explain for us how this situation is happening.
Thank you for all your great work.

I couldn't edit my last post so I'm putting a new reply to add some info.
Both my og and ogp have the same apn settings. I tested them using the same sim card.
I just put another unactivated sim card in the og and surprisingly it picks up lte immediately. I don't want to activate this sim card right now so I can't tell if it would go away if I activate it. I hope this info would help a little bit.

Help! I have the exact same problem. I have a brand new att lg optimus g and unlocked it. Popped in the sim and bam LTE! Ran a bunch of speedtests, drove to my friends house and it switched to 4g and hasn't come back. The guy at tmobile wasn't sure. ...any help ? I'm going to root this and try flashing a new rom...maybe radio?
Seems to be an issue with this device, perhaps it's doing something to the SIM cards (who the hell knows) because mine did/does the exact same thing, and here's my particular example:
When I first got this LGOG last Sunday (8 days ago) I put my T-Mobile microSIM in it (one of the TM9190 series SIM cards) and got LTE off the bat without any issues. I kept the stock ROM on here for the first day or so and never had any issues and then I got into doing the typical root/unlock bootloader/install recovery/backup stock ROM/flash custom ROM/etc routine and even after that I was still able to get LTE working almost immediately.
A few days ago I noticed that the LTE wasn't being picked up, and it hasn't since. I've flashed several radios for testing (.33, .48, .33-.84 hybrid, etc) and the ones that are LTE ready still didn't get LTE so I just flashed the whole thing back to complete JB stock (JZO54K, the last available LG build) and even that didn't help - I've yet to see LTE show up in any respect at all with that SIM card.
Now the interesting part:
I have another microSIM that had prepaid service a few months back, bought it at the same time as the one I use for my primary service - they were on sale from T-Mobile online for $.99 each so I got two and kept the other one around just to have it.
In spite of all the flashing I've done in the past few days, with like 5 ROMs tested, a kernel or two, and maybe 7 flashes back to pure stock using LGNPST and the LGE970AT-01-V20j-310-410-MAR-08-2013 ROM (the stock one), after all that flashing torture I put this LGOG through, as soon as I put that other SIM card in it - which is not active at this time - and powered up the phone I got an LTE signal right off the bat without a problem. Had already made the APN changes to fast.t-mobile.com so they just kicked right in and wham, 4G LTE right there on the status bar.
And yes, the SIM cards are the same "series" (?!?!) with TM9190 imprinted on both of them - they also have the same code on the front side (620048) and their serial numbers are just a few digits off in sequence - like I said, I bought both of them with the same order so, it stands to reason they'd be from the same batch.
Loaded a few web pages on the T-Mobile prepaid billing site (it's what comes up when you insert a prepaid already activated but not presently in use SIM, very limited but it does work), checked the system stats, everything showed me I was connected to T-Mobile with their LTE service, this phone, and that other SIM card including the status bar icon being the traditional 4G LTE one (big 4, little G, little LTE under it).
Then I rebooted the phone and that was that, the LTE capability just up and vanished like a fart in the wind, and I've done most everything that I could do - including reading a few hundred posts in two dozen threads - to get it functional again and it just doesn't work anymore.
I suppose it's not a big deal to me since T-Mobile's HSPA+ is fine with me, I regularly pull in 10-15Mbps on a speed test in various locations (was out earlier today testing stuff in the eastern parts of Vegas), but I am somewhat pissed that I am unable to get that LTE functionality working again.
Tried:
- a complete stock flash, several times, of the AT&T JB ROM, no dice
- all the currently available LTE-capable radios, no dice
- an AT&T SIM but it's not provisioned so it doesn't work at all (T-Mobile doesn't do that, hrmmm... their SIM cards work months later even after the number has been assigned to another customer, go figure)
- all the hidden menu options (3854#*970#, WCDMA automatic, tried forcing LTE only, several other things), no dice
- tried manually setting LTE only with *#*#4636#*#* using custom ROMs, no dice
- adding the LTE enabling lines to build.prop, no dice
Nothing works, so I'm only left to conclude that either a) T-Mobile is doing something funky (highly unlikely), b) something is borked with the phone (potentially true), or maybe c) the phone is doing something to the SIM cards after a reboot or any change in the network mode from LTE to anything else (leaning towards this possibility more).
I can't explain it, I can't figure it out, and I can't get LTE working anymore but as I said, the HSPA+ is enough for me as here at home the LTE signal is somewhat weak (1-2 bars at best whereas HSPA+ pulls in 5 bars and a -61dB signal almost constantly).
I wish I could figure it out because I'd like to do more testing with LTE enabled but apparently once LTE gets disabled for whatever reason after having it actually working, not once but twice now it just dies and never becomes possible again.
Stranger things I suppose...
If anyone does ever figure this fiasco out, post whatever solution you came up with or discovered so the rest of us can give it a shot as well 'cause I'd love to be able to enable LTE if I so chose. This is pretty frustrating in the long run - if it never ever worked at all that would be one thing, but having it work then suddenly just disappear never to work the same again, that's just pooched.
Slightly off-topic, but how's the battery life compared to AT&T? Or, in general, is it okay?

Thanks for posting your experiences. I've had the exact same problem, though I've never been able to get LTE working at all with my phone. I'm planning on taking a trip to a T-Mobile location within the next few days and see what they can do. Maybe they'll let me try putting my SIM in some of their display phones to see if I can get an LTE connection. Then at least I could probably rule out the SIM as the problem.

Make sure that your phone has the fast.t-mobile.com APN info in place (just create a new APN with that info if needed, maybe call it T-Mobile LTE and see what happens. My guess is if they put a new unused SIM into your phone it'll most likely kick into 4G LTE right from the start (as long as the APN is in place) and then at some point it'll switch to HSPA+ and it'll never go back like it has for those of us that have noticed it.
Who knows... it's probably just one of those things.

Could be...I've always had my settings on T-Mobile LTE, and I even called T-Mobile and confirmed every field in the settings with them. When I explained that I still couldn't get LTE, they had no other solution for me. The lady on the line didn't even know that LTE was faster than HSPA+, so I wasn't exactly expecting any sort of resolution. I think the reps in-store will be more suited to this type of issue.
Hi, I have an LG V10 that I purchased from TMOBILE. I switched to AT&T, and brought my T-Mobile device with me. Everything works fine, but I cannot get 4G LTE service at all. I have tried 2 APN settings, and that does not help. I live in a large metropolitan area, and I know that 4G is available here with AT&T. Does anybody have any idea why I can only get 4G and not 4G LTE?
Thanks!
This happened to me when flashing a custom Rom, the fix for me was to change the network speed to 3g or 2g then keep changing Ap's until you see you are connected to a network. Once you see that you are connected, change it back to 4gLTE. Let me know if this worked for you.
This is the APN I use and got LTE to work. It's old APN but it works for me.
Name-LTE
APN-phone
proxy, port, username, password-Not set
MMSC-http://mmsc.mobile.att.net
MMS proxy-proxy.mobile.att.net
MMS port-8080 (In order for MMS to work with adblock plus, I use 8080 instead of 80 because using port 80 will cause the MMS not to work)
MCC-310
MNC-410
Authentication type-Not set
APN type-default,mms,supl,hipri (hipri is what makes LTE to work. Without using "hipri" I only get 4G, not LTE. No need to use "fota". It is for tablets)
APN protocol-IPv4
If changing to this APN setting and you still don't get LTE, reboot the phone.

Wow, i was thinking i was the only one with this wierd problem, i had a lg g3 tmobile with this issue, when i was on wifi for large periods and the back to data, the 4g lte appears like it was working fine, but it never gave me access to inteternet, then i had to revert to 3g or 2g, and when it connects and works, i revert back to 4g lte and works fine, until i get wifi, and the same all over again, but this only happen to me with lg on tmobile, i had htc, samsung and this problem does not seems to happens with that brands, so i tougth it was the lg g3 itself and i sell it, but now i get a brand new v10 with tmobile and the problem is still the same, and i don´t find anything on the internet about it, until i see this post, do you know why is this happen? im on mexico, and i use my phones whit telcel

when i hit the apn unlock option appears a message that tells me: "apn has been unlocked" or something like that, but the phone stills the same, do i have to do something else besides manually enter apn settings from my operator?
A word of advice I have an unlocked t-mobile lg v10 and I have had the same issue as you and believe me I tried every possible fix and nothing worked until I tried this fix ( put your sim card in another AT&T device in my case my girlfriend has an AT&T iphone 6 and leave it for a minute or 2 once you see the 4G LTE on that device remove it and put it back into your phone and you will have the 4G LTE all the time, of course you need to set up your apn but like I said I spent a whole month and tried everything before I came to that fix because nothing else worked) I hope that would help you.
I totally switched iphone 6 SIM on unlocked LG v10 ,,,but i saw LTE for 5sec and then back to 4G ...
Don't know if it will work ..
Just a network access problem, you should save yourself some time and just.... Call AT&T customer support?
Or hit the AT&T V10 forums for correct APNs. I'm sure you aren't the first person to deal with this issue.
Yes u can have 4G LTE ...just activate with a AT&T 4G LTE IMEI

i have the same senario...recently moved to AT&T with the UNLOCKED Tmobile LG V10 and every thing works just fine with AT&T SIM except no 4G LTE and when you asked At&T they will try to convince you to buy their device to get 4G LTE signal....it took me a while to figure it out that u can get 4G LTE on an unlocked LG V10 if u activate the service with any AT&T 4G LTE capable device IMEI..... One more thing.. u are on your own to provide the LTE capable IMEI to customer service. That means don't except to walk in to AT&T store and borrow the IMEI from their display unit..coz they wont let u do that.....
The T-mobile phones pick up perfectly on ATT, it's most likely an APN related issue.
I purchased a refurb H931, and while waiting for my new SIM to arrive, I went ahead and Frankenstein converted to US998 and unlocked the bootloader. Now I have my SIM, but data isn't working. :crying: I've tried a couple AT&T MVNO SIM cards. APN settings are correct, but data doesn't work (no data at all, as far as I can tell, not just lacking LTE). I haven't changed anything in the hidden menus, and it seems that all of the US998 LTE bands are available like they should be. Factory reset and re-flashing stock Oreo didn't change anything. I'm on US99820d firmware with Magisk and am just trying to use AT&T's network. Does anyone know what I can try? I'm afraid this is a $300 brick that I can't return since I've already changed firmware and unlocked.

Now I have my SIM, but data isn't working. :crying: I've tried a couple AT&T MVNO SIM cards. APN settings are correct, but data doesn't work (no data at all, as far as I can tell, not just lacking LTE). I haven't changed anything in the hidden menus, and it seems that all of the US998 LTE bands are available like they should be. Factory reset and re-flashing stock Oreo didn't change anything. I'm on US99820d firmware with Magisk and am just trying to use AT&T's network. Does anyone know what I can try? I'm afraid this is a $300 brick that I can't return since I've already changed firmware and unlocked.

I just set my mom's US998 up on AT&T last night.
Go into Settings/Mobile Networks, make sure
1) Mobile Data is on (it probably is, just double check
2) Go into System Select, make sure it's not on "Global" but on LTE/GSM/UMTS. If it is not, change to that and reboot.
3) Tell me the APN you have. I have two. Make sure the APN you are using has green checkmark, that it's active.

Mobile Data is on and set to LTE/GSM/UMTS, submode LTE/Legacy 3GPP multi. The phone automatically uses the correct APN settings for Red Pocket AT&T. I also manually created another APN entry with the correct settings, but data doesn't work when either entry is selected. I tried a FreedomPop LTE SIM (also AT&T), and it doesn't work either.
I know with the op n200 metro version you could put your T-Mobile sim in and unlock the phone to work with TMobile automatically, I can't find confirmation anywhere if this works with the n20 as well, does anyone here know?
I just tried with a T-mo sim card in Metro by Tmo N20 and it didn't work

Was the n20 brand new and the T-Mobile sim inserted before turning the phone on the first time? I read that's how it works on some older phones, I think metro blocked it finally but was hoping it might still work.

yes, I received the phone in mail this afternoon, Brand new and first boot was with T-mobile sim, no service and Mobile network status showed "Disconnected"
The Boot animation did change to T-mobile on a reboot with the sim inside but still no service
As I was playing around with the phone, I stumbled upon a weird way to get signal by trial and error got 4G and 5G data as well but when Wi-fi connected, data seems to switch back to 2G. Let me know if you want to know how

Sure, here it is:
1. Boot the phone with T-mo sim inside the device, once booted you wouldn't have any signal
2. Go to "Sim info & settings" > "Preferred network type" and choose "2G/3G(Automatic)"
3. Reboot the device, once booted you should see signal along with 2G icon
4. Now go back to "Preferred network type" and select "2G/3G/LTE(Automatic)", you should now have 4G (Texts and data works but call dropped)
5. Now switch to "2G/3G/LTE.5G(Automatic)", you should see 5G network (Texts, calls and data all worked fine)
5G was stable for several hours until I connected to Wi-fi and when I disconnected Wi-fi, I noticed that data said 2G.
Let me know if the above steps worked for you

Did you get an incompatible SIM error, or just no signal? Also, you can't just put a Metro SIM in a phone and have it work. You have to call them and tie the IMEI of the phone.

I was able to test it and the tmo sim doesn't work. you only get edge signal.

If you got any signal, then it should work. Try changing the APN settings manually

OP is talking about the other way around, T-mo sim in a Metro device
Nord N200 had a bug where the device could be locked to Metro but worked flawless with T-mo sim.
That bug being patched is what OP meant by "blocked"

Yeah, I got that backwards. But if he's not getting an incompatible SIM error with a T-Mobile SIM in the MetroPCS phone and actually getting an edge signal, maybe add a new T-Mobile APN profile. Should work in theory.

Thanks! Good find! Yes I was able to reproduce the behavior. Also in my case it seems that the 5G/LTE will revert back to 2g after some idle time. But I can use the airplane mode to repeat the process (without rebooting the phone) to repeat the process. I was able to reproduce on another metro phone as well. must be some kind of loop hole.

I know I already mentioned this, but did you try making a new T-Mobile APN profile and deleting the old one(s)? Maybe you wouldn't have to go through that ritual. might work, or not.

I just factory reset my device and tried this, deleted existing APN and added T-mo APN, doesn't seem to work
I take it you're not a MetroPCS customer. Must be something baked into the OS. I wonder if it still has the MetroPCS bloatware since it booted with T-Mobile boot animation? Anyway, there are services on eBay that will unlock this phone through the MetroPCS unlock app. I'm not selling anything just letting you know that's an option if you didn't already know.

It installed the T-mo bloatware and removed metro bloatware as soon as it booted. Yeah, I'm not a Metro customer, I'll usually just leave it alone for 180 days and unlock it afterwards

Ah, but you need active service on it for those 180 days to be eligible to unlock it no? And now that it has T-Mobile firmware how can you unlock it from Metro? I'd download the MetroPCS unlock app from the play store and run it to see what it says.

In theory, it's 180 days of active service but in reality, they've been unlocking 180 days after activation. I pay for first month and then throw it back in the box.
Also, I didn't see the unlock app as part of bloatware, its built into settings > about. It'll pull up the same screen as in Unlock app and we can try to unlock from there but obviously, throws the error showing it needs 180 days of service to unlock and is not eligible currently

On eBay it's 75 bucks to unlock. Thats like 2 months of service and you'd be able to use it in a few days instead of having a paperweight for 6 months. Thats what I did on my old Moto One 5G Ace.
