No LTE (Ktoonsez AOKP)

Hello,
I'm having an issue with the rom I have (AOKP Ktoonsez) when I turn on data I get H+ at the top. How do I get LTE? I went into that menu by putting in *#*#4636#*#* in the dial pad and putting it into GSM/LTE, but I still get H+. I'm with Virgin Mobile Canada. Here's my APN info:
Name: Bell
APN: pda.bell.ca
Proxy: web.wireless.bell.ca
Port:80
Username: Not set
Password: Not set
Server: Not set
MMSC: http://mms.bell.ca/mms/wapenc
MMS Proxy: web.wireless.bell.ca
MMS Port: 80
MCC:302
MNC: 610
Authentication Type: Not set
APN Type: Not set
Anything missing? This rom does have LTE and I went into the FAQ page, the dial pad method was the only way we could turn LTE on. Thanks.

I'm on att so I'm not entirely useful in the regard to the fact tour on virgin, but are you absolutely sure that apn set up is for lte, that's the first thing I would check.

Yea I know you can get lte working just do a search there is a thread on it and it has everything you need to get it working.

Delete all your apns. Do a new one for bell lte. Then changed preferred network to lte/gsm. Restart phone right after. You should be able to start seeing 4G now. Make sure you remember to restart phone after you change the settings.

Alright, I think I'm going to call them to get the LTE APN in case I am actually missing something. Otherwise I may need a SIM card change.

In the *#*#4636#*#* menu under phone information, try setting it to LTE only and see what happens. I keep getting H+ or less on my CM10 rom unless I do that even when I'm in an LTE area.

Make sure you have LTE/HSPA enabled in Settings>Wireless and Networks (More...)>MobileNetwork>Network Mode. Sometimes when I flash a new rom it changes. I have it HSPA only because saves battery.

When I set it to LTE only, I lose signal to my carrier does that mean anything at all? And for the options under settings I only have a choice between two, GSM/WCDMA/LTE and GSM/WCDMA preffered.

Pick the lte mode and click the lte apn and restart your phone right away. It should work right after. Btw if it says 4g,it means lte is working

Also a Virgin Mobile Canada customer and my S3 has NEVER said 4G or LTE in the signal bar.... H+ is what it displays on stock touchwiz, AOKP CM10...

I'm a Virgin Mobile Canada customer as well. I've set my preferred network type to LTE/GSM auto (PRL) by accessing the "Testing" menu (dial *#*#4636#*#*) and have selected LTE/GSM/WCDMA by going into my mobile network settings. The only two modes I can select from are LTE/GSM/WCDMA and GSM/WCDMA preferred
I've noticed the following:
-most of the time I'm on either the HSPA or HSPA+ network
-there are times at which my notification bar shows 4G (which I assume is LTE) but it definitely isn't as frequent as when my phone was unrooted and on stock
-this one is weird: occasionally I lose total mobile and data connection for about a few seconds and a "warning" icon shows up in the top left corner of the notification bar. When I expand notifications it says that the connection to the VIRGIN mobile network has been lost..or something along those lines. I'm usually able to reconnect automatically within a few seconds but this is definitely a weird one since I've noticed it only after flashing Task&Ktoonsez AOKP. Anyone encounter anything similar to this?

Hmm maybe this is just Virgin Mobile problem? Thing is the ROM I was on before, (Team Insomnia JB Touchwiz) it showed 4g when I turned on the mobile data but I was getting no where near LTE speeds. I also tried switching to LTE mode and clicking the LTE APN and reboot, but all it does is go back to WCDMA Preferred mode. I got a SIM replacement from Virgin Mobile but still no luck after this.
EDIT: I think I got it, if you recently were on a Virgin Mobile Supertab or changed from an older phone that didn't have LTE, make sure that Virgin Mobile systems know that you own a Galaxy S3. I went into my Virgin Mobile "My Account' and it showed my phones it only listed the HTC Legend I had few months ago, but not the S3 itself, and beside it saying this device runs on a HSPA+ network. I'm getting this fixed on Monday so I'll see what happens then. If somebody can do it sooner though if they have the same issue, that would be great too.

no LTE on at&t - unlocked m919

I've seen several discussions about this but didn't seem to find a working solution. I'm currently using GNF1 V3 NB4, I tried using the apn settings for at&t and also called them to make sure they have the correct imei number. Also, for some reason under the "Network mode" I don't have an LTE option, I only have WCDMA/GSM, GSM ONLY AND WCDMA ONLY. I am able to get 4G but no LTE. Is there any solution or any other way to solve this problem?

Change ro.product.name= in the build.prop to say jfltetmo

will it also change the speed or just add an "LTE" symbol?

Give you the LTE option in network modes and change the icon. Speeds? Probably since youll have LTE back

ok, i have the LTE option in "network modes" now, however the speed is more or less the same and I don't have LTE bar, not sure whether it's because of my current location or what.. is there anything else I could edit to try to make it work?

If I change the ro.product.model , name and device to at&t values would I get the LTE speeds just like an at&t s4?

When I bought this phone from T-Mobile I was still on an AT&T plan. Before I jumped ship over to Net10 Wireless I used AT&T's LTE all over Pensacola. That was on a sim-unlocked, unrooted, otherwise 100% stock M919. Did you double-check your APN's? Perhaps you're just not in an area where you can pick up LTE?

Yes I use the correct apns the ones that at&t gave me, but im gonna try to go back to stock then change the apns to at&t and maybe that will work.. but even if it will, I don't know if I could keep using GNF1 or would I have to use a different rom, anybody else have or had issues with getting LTE on at&t while using custom roms and knows roms that work? (Preferably tw)

See your network type in settings > about phone > status. Try to get LTE with your AT&T SIM on another phone then install it back to your M919.

[Q] unable to access 4G-LTE on unlocked LG G3 D850

Hello all,
Prior to going to the US last September I had checked with my carrier (Vivo) in Brazil that the 4G-LTE frquency they use is 2.600MHz. When in the US, I managed to buy the above said device and brought home. Back home, as it was
unlocked my carrier's SIM card worked like a charm. It downloaded from the carrier's network the APN configurations and all was fine.
I went to the carrier's shop to try the 4G-LTE so I could bump up my contract. I tried the clerk's SIM card (he has 4G-LTE) and the signal icon changed from 4G to a smaller 4G with underscore LTE. But only the 3G and 2G APNs were found when searching networks manually.
I did rooted the device and removed the bloatware that came along using this xda-developers how-to.
Any idea how can I get 4G-LTE access on my device?
Thanks in advance,
gtludwig

I suspect your APN need modifying. Check the clerks APN settings against yours.

Your APN is set wrong. I'm not sure how to change it on the stock AT&T ROM though.

It's in the settings/tethering and networks/mobile networks/access point names. I have consumer cellular, but it leases from ATT, so it has slightly different settings, though ATT APN will work ok.

I had thought that menu was just tethering settings. That's embarrassing. :S

Phone stays on HSPA when LTE is available

So I own a D851, currently on T-Mobile with good LTE speeds in my area but quite often the phone switches to HSPA and doesn't utilize LTE coverage when I need it. I end up having to either switch data off/on or accessing the radio settings menu and setting it to LTE ONLY. I understand the slower network coverage saves battery but to just stay there I don't get when I'm getting download speeds of 9mb on HSPA and 30mb on LTE in the exact same spot. The thing that sucks about setting the radio to LTE ONLY is that I can't browse while on a call. Anyone know a workaround?

I had the same issue with ATT, unlocked phone. Made sure the APN was correct, tried may other APN settings, and finally called Consumer Cellular. They advised I did, indeed, have the correct APN (my first version). They did some type of reset on their end, and viola.
On my OnePlus it was the similar. APN was correct, same APN as the G3, but until I called CC, and their reset, phone would not show LTE at all, only H and H+

apn settings?

What are the apn settings that are working for you? I've tried several times to address this issue with CC but lte STILL isnt working on either of our 2 devices. Had no problems when used with an att account.

I am still having this same problem on my LG G3 (vs985) on Cricket Wireless

Can not connect to 4G/3G.

Hello there, I'm in need of your help again.
My SGH-M919 has a problem, it cannot connect to 3G/LTE (Not even EDGE). My carrier uses the 850 mHz band for GSM and 1900 mHz for UMTS, so the phone should be able to use them. The thing is, it doesn't. It only connects to GPRS and the signal is very erratic and weak (Usually 2-3 bars). Sometimes I get SMSs from my carrier saying that I missed like 5 calls when my phone never rang once. I live in a zone with good 3G coverage, so it's not the signal.
I'm currently rooted on Android 4.4.4 (NH7). I already tried selecting "1900 WCDMA" in the *#2263# service menu but that only causes the phone to lose all the signal (And it's a problem to change it back, without signal the service menu doesn't work and I cannot change the Network Mode in Settings).
I've tried to select "WCDMA only" mode before, but my signal just goes to zero (The circle with the slash) before changing back to "LTE/WCDMA/GSM (Auto connect)" automatically.
I also cannot use the Network Operators option. Using "Search now" makes it search for a few seconds before showing the message "Error while searching for networks". The "Select automatically" one shows the message "Unable to connect. Try later" and then connects back to my carrier (Movistar)
My APNs are configured (They did it themselves when I inserted the SIM, but I've configured them manually before). The SIM card works, I tried it in another phone and it got 3G immediately, I also tried another SIM card on the GS4, but the result was the same. Someone told me to upgrade to the latest firmware (NK2) while someone else told me to flash the MDL modem. (Is that even possible? I read something about KNOX blocking all downgrades after 4.3).
Since I couldn't find any direct solution to the problem, I'm recurring to you.
Thanks.
P.S: I didn't change the LTE Band Preference option in the Service Menu because the last time someone messed with it, my IMEI/Baseband went completely nuts, I thought the EFS got corrupted, but they magically appeared everytime I enabled the Airplane Mode (So I was able to select Automatic in the ServiceMenu and they got fixed). Also, I don't live in a LTE area although once during a very strong thunderstorm, I got 4G for a few minutes before going back to G).

*bump*
Any ideas?

Did you put a check mark in data roaming?

I've tried with and without it, it doesn't make a difference anyway.

Does it show you have an ìmei # other than all zeros?
Don't post it just a yes or no.

My IMEI is fine, the phone connects to the carrier network but it stays on GPRS (and the signal is always dropping)

I'll try that later. Will I have to re-root and re-install TWRP after flashing NK2?

I have a similar problem with my M919 on the Tmobile network. Using the *#2263# menu I can not get mine to work on WCDMA (4G) either. I can chose GSM /LTE only and my phone works normally but no 4G signal. If I chose WCDMA I get no signal. I can see it trying to connect and immediately dropping the signal. If I choose any option with WCDMA included it has erratic signal and will lose the signal most of the time when I try to make a call. So basically I have the choices of GSM only or GSM/LTE only. Before I discovered the secret menu I was stuck with GSM only in the phone's settings. This has been going on for months. Tmobile changed my SIM card and it didn't help. I've rooted and unrooted my phone (using autoroot) and even tried different modems (even worse signals) and now am back to stock rooted NK2 firmware and modem. I have given up and decided to get another phone (not an S4). My wife's S3 gets great 4G signals in the same location by the way. I wonder if anyone knows why our phones can't use 4G. I am beginning to think it's a hardware problem but I'm way out of warranty on mine.
