hello every one.
My lte doesn't work. I already test with the rom paranoid and CM.
I m from morocco our 4g is new and i think is the same as the europe 4g (lte).
Do you have any idea ?
Pls help
Thank you for your time
up
Help pls i need to flash modem ?
Which carrier are you using in Europe? Are you roaming from T-Mobile or have you purchased a different service/SIM card in Europe?
Also, what country are you in specifically?
There was a guide somewhere on XDA regarding Qualcomm processors and band unlocking using QXDM (LTE) and QPST (GSM/WCDMA) though I forget the exact name. I believe there was also concern that it could damage antennas. Also I have no idea if it actually works and mucking around in the NV RAM space is very risky. I would not advise it.
Is at least the GSM service working? If so, is it really that bad that you need LTE? Personally I would leave it at "oh the gsm works, I'm good". :good:
Depends on the carrier you are using, is your phone unlocked? I would assume that it is since your can receive gsm signal.... Anyways, what you would want to do is check your network's APN and check our phones APN settings and add the 4g/LTE APN settings to your phone manually... Then restart your phone and try again, make sure you select the apn after adding it so you know it's active. Try that. If that doesnt work, then go into your APN settings again and just do (reset apn setings) or something along the lines of that which resets/restores your apn settings back to normal/default.... either one could work, try the first one first ofc!

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.

I have an unlocked sprint g2. I moved to Oman a month ago. Now gsm services work fine but 4g and 3g doesnt work on my phone. Can anyone explain a possible solution to this? Do i need to flash a baseband? Will this issue be corrected if i root and flash a custom rom? Thanks in advance guys. Appreciate your help.

first make sure the 4g and 3g bands of your current provider are supported on this phone. If they are, then there is a rom which might help you get 4g or 3g but i dont remember the name of it (terrible i know) 3g could have to do with the apn settings as well...

Hey thabjs for the reply. I know about the 3g settings, even i thought about the apn settings. But then there are no options to change apn settings in this rom. Perhaps if i change the rom i will be able to change fiddle around with the apn settings?
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,

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
I purchased my phone (h815 US model) online from swappa and I love the feel and look of the phone, Love the camera, BUT my phone wants to stay on hspa all the time. Where i had 3 or 4 bars on my s5 active I get HSPA unless I go in to settings and sellect ATT:LTE from network operators which only last until my phone goes to sleep then im back on hspa. Anyone else experiencing this? Or anything i should try? Thanks in advance for any help!
Bumpers just in case someone who knows didn't see it. Sorry won't bump it again!

Maybe with hidden menu access via dialer,you can permanently enabled it...I don't know the actual code that might work for your device..but you can find it through here..In general threads maybe
I had to set the proper APNs on my H815, additionally I had to tell it to use GSM/WCDMA/LTE Auto under Network Mode in the Mobile Networks settings.
AT&T APN settings

After that, it's been using LTE where available.

Thank you @Daptonic . I was attempting to use the "ATT nxtgenphone" APN because it works better on ATT devices but I guess the ATT Phone APN is needed for non ATT devices. Rebooted phone and it went straight to 4g. Thanks for responding.
Edit: dammit, it went back to hspa again......
Hello there hope all of you doing well
i had Tmo SGH-T999 S3 which is unlocked but after unlocking its stuck on 2G Network i couldn't use 3g network
i search on google and i found this code :*#197328640#
but i don't know how to use it any way can you help me
wish best times 4 you ^_^
Did you sim-unlock the phone using a code?
I'm also having this issue. I have TMO SGH-T999 S3 sim unlocked before via software (not unlocked via code) and always stays on E (2G). I am thinking that i got messed up after the unlock. My IMEI is still intact btw.
First thing is to double check that your IMEI exactly matches the one on the sticker under the battery. If it checks out, the next best step is to reflash your current or newer stock firmware. (This can be caused by mismatched firmware so by flashing it you will either fix the problem or eliminate it as the cause).
You may also want to check your IMEI against the blacklists online. Especially if you bought it anywhere but a retail store.
Unlocking via code or secret menu should not affect radio bands available in the phone.
WCDMA Band preference
I've checked the WCDMA (3G) band preference available in my T999 S3 and below are the only option available:
The mode preference menu: *#2263#
The information menu: *#197328640#
WCDMA 850
WCDMA 900
WCDMA 1700
WCDMA 1900
WCDMA IMT2000
WCDMA ALL
... and found out my carrier band preference for 3G is 2100. Seems i'm out of luck for 3G data and since this T999 cannot support 4G LTE. I guess i'm stuck on E (2G) data unless i use WiFi.
P.S - Is there a way to add a 1800 or 2100 band preference to WCDMA? :fingers-crossed:
Check the General section in AT&Ts forum. They had something like this if I remember right. They could enable use on a different band, but I don't think it would stick after a reboot. It's been a long time since I looked at it though, so they may have made some more progress on it.
Goodbye 2G (E) data connection
I'm happy to report that my (WCDMA) data speeds is now functional on my SIM network carrier! :good: Loving the speed browsing at last . Although showing as 4G but i know my T999 is not capable of that and not very sure.
Again, thanks DocHoliday777 (I don't know how to link your name) for giving me the idea about the Modem mod. I just followed the guide on the link below and used the NV Data backup from T999L file. So for any users of T999 you can try this mod but please do it at your own risk and don't forget to backup.
I hope this T999L modem mod can be included on the newer root66 baseband/firmware so it can be permanent?
Anyway, just follow the guide on the link below and hit thanks!

P.S - To access the modem setting on my SGH-T999 I've used the code *#0808#. And my final WCDMA setting i chose WCDMA ALL. Goodluck!
