Hi Guys ..
i have a new note2 ALJ1 baseband, ALJ3 build .. stock Thailand firmware.. rooted then stock kernel put back. no updates showing on kies.
MY phone is not changing from edge to 3G/H++ automatically.
Thailand has sketchy 3g coverage so changes a lot.
when i am in an area that has 3g activating data the phone seems to prefer going to 2g/edge instead of 3g ..
and the only way o seem to be able to use 3g is by changing network mode from auto to WCDMA ... then having to remember to change back after i finish internet usage or i will not even get a phone reception when i get out of a 3g area
its not a sim card problem i do not think .. i had an S2 then a S3 with the same card and did not have this problem
I've met one other person having the same issue locally
i've tried *#197328640# and aquisition order is umts-gsm.. cannot change as it always says invalid choice
is there a hidden settings menu perhaps for setting preferences on priority perhaps ?

I've used my Defy in Korea and there was no problem.
Yesterday I enrolled T-mobile prepaid plan(Monthly 4G $50 and changed my SIM card.
Talking and Texting is working but 3g connection isn't working.
On the status bar, there is "G" sign which means GPRS connection (I found it in google)
When I used Defy in Korea, there was "3G" sign or "H" sign which means 3G/HSDPA(much faster than GPRS)
I think my Defy is only taking GSM(GPRS) frequency.....
I setup "*#*#4636#*#* -> Phone information -> WCDMA preferred or WCDMA only" but still not working.
Now I'm about to try to find a US ROM and flash it... Will it be helpful??
I don't want to lose all the apps & settings........ but if it fix my problem, I'll try it.
What do you think about my idea??
You don't need to flash a new ROM
Your problem is quite common because your ROM (Koren) uses a different baseband. The baseband for US 3G networks is different. Just download the Defy Baseband switcher app from here:http://forum.xda-developers.com/showthread.php?t=1052745 and apply a Baseband for US. This should fix your problem. So, you won't have to loose your installed apps and settings.
my phone can not connect to 3G networks in most of our city, while it used to work just fine in these same places. at first i thought there must be something wrong with the carrier's base stations. but today i tested my SIM card on another LU6200(Korean version of Nitro HD) and it works perfectly both on 3G and 2g networks on that phone. but when i put it back into my phone, it can only get 2G signal. if i set the Preferred Network Type to WCDMA ONLY, it got no signal with just a cross on the signal bar. i have to put it back into GSM ONLY mode to receive signal.if i go out, i can get partial 3G connectivity here and there, but not consistently. sometimes even if i have full 3G bar signals on the status bar, i can not make calls or connect to the internet.i've got this problem probably after i tried to forcibly go into the Phone Info menu.i got repetitive " the process com.android.phone has stopped unexpectedly" promps , and i just ignored it and tried again. now ,2 options are missing from the menu, LTE/WCDMA/GSM and LTE Global.in place of them, it's UNKNOWN. i already tried flashing KDZ package of no avail. Does this mean a hardware malfucntion or software glitch?Please help!Thank you in advance

Well you do HAVE GSM only selected. THATS 2G(EDGE)
for 3G you would need to select WCDMA

Hi i'm not sprint user, i'm using different provider in my country
i have 3G all the time (doesn't have LTE here yet), voice call and sms working. But my 3G speed is really2 slow, somehow my speed is capped to 50kb/s normally i can get 200kb/s in my area. i have samsung s1 CDMA here with same provider and there's no problem. i ned patch for custom ROM but not with stock ROM
Some said that because sprint lock my EVDO if i'm using different carrier. The carrier provider here not to friendly so i cannot ask for their help :laugh: . is there any way to unlock that?
I Already tried ##RTN# and i have trouble to enable my voice call and sms , and i already tried to zero my EFS still no go
Doing a little research, my AN-AAA status is pending in DEBUG. I already tried LG service Menu to set "undetermined" but somehow the setting is not stick, after reboot, the 3 option there just blank are that normal? my parameter for data stick tough
APN modifying not helping, what ever i input i still have 3G
To be more clear i'm from indonesia, using smartfren carrier.
Maybe i can get more clue from you guys non sprint user. and helping other user :victory:
Thanks, and sorry for my bad english :angel:
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)
Update to full NK2 firmware and see if that will fix it

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.
Hello everyone , I'm from Morocco and I need help with my device's Mobile Data.
To begin with, I've got an S4 mini 19190 3G variant, I installed a cyanogenmod ROM, it's a cm13 version, android 6.0.1. I'm using a TWRP recovery.
I've had a cm12.1 before and had the same exact problem: I'm always stuck on EDGE network .
I've gone to the settings, and made sure to choose 3G in the preffered network type.
My APN setting are correctly configured.
I've tried forcing the device to choose WCDMA by going to Phone Info. Choosing the WCDMA option disables Mobile Data and calls, with emergency calls enabled only.
Choosing the "WCDMA preffered" option doesn't change anything, it's still on EDGE.
I've looked for a solution, and noticed that some people had a problem with IMEI number, I've checked it, it's the same as the one on the back of the phone.
Anyone got any idea on how to fix this? Thank you .
Are you sure that your area has any WCDMA connection? Can you check with another phone?
Yes, I've already had H+ connection on the same phone but with a different version of the ROM, and my father has H+ working perfectly on his SGS5. I didn't try with another phone, I'll try and see if the problem comes from the SIM.
Omg Thank you! Why didn't I think of that! (How stupid of me) I tried my SIM card on a different phone (that had H+ working on it) and it went on EDGE network, and I chose WCDMA only and the connection was lost. There is a problem with my SIM card, I'm going to contact my service provider to fix this
Thanks Again!!
