Phone -> Keypad
Key in: *#197328640# (Service Mode Menu will appear)
If you are using data on SIM 1:
Touch: [5] BAND SELECTION
Touch: [2] WCDMA BAND
Touch [1] WCDMA ALL
If you are using data on SIM 2:
Touch: [6] BAND SELECTION S
Touch: [2] WCDMA BAND
Touch [1] WCDMA ALL
Press the Back key to exit, or Menu key then END.
Note, the above can help to lock your network on the selected wave, but data can only be activated on one SIM.
USE WITH CAUTION.
Hope this helps.

Your phone is using mtk or Qualcomm chip? Check it with app from play store. If its mtk, this method won't work on your device as this one is for Qualcomm.

Settings > Connections > More Networks > Mobile Networks > Network Modes
Check if 'LTE/WCDMA/GSM' is checked.

I know that, but my device does not have LTE option to choose.This is regional locked by software becouse the devices for our country didn't need LTE until now.

problem with network needs to be repaired lg-g3 d885

I wanted to fix internet network on 4G so from dailpad I enterd
*
855
#
3845
#
which is advanced way for modifing on mobiles settings, but once I enteren on:
LTE-ONLY> Modem Setting > LTE Band Selection
and by fault I chose on a band(don't know which one) then the 4G is refusing to connect at all. <<<-------problem starts from here
I tried to repair it by choosing these bands: (band3=1800Mhz & band40=2300Mhz) sence it's our bands here in Saudi Arabia for STC company, but it didn't work.
In my city the only ban activated is 40=2300Mhz.
Do you have any solutions? let formatting be the last solution.
if I upgraded to lollipop would it solve the problem?

Did you check your APN settings?
Try deleting your existing APn settings and then reimporting it

it is the first thing i did

I updated it to android 5 but the problem still !!!

have you tried this?
in LTE ONLY > Rat selection> gsm/wcdma/lte auto and uncheck every bands in lte band selection?
and after that check apn settings ...
i've messed up soemthing in NV values of phone and when i choose gsm/wcdma/lte in mobile networks , there is no apn (which i have), but when i choose gsm/wcdma only , apn are there

no 3g -4g option

hello .. i got s3 sgh i747 from my frnd ... the problem i m having is m not able to switch network .. like its just running on 2g network m not able to select myself the network mode ... like in normal fones i can select 2g-3g or 4g whicheve i want..
fone is imported from usa and m in india ....
the solution i know is rom change ... is there any other way out ??

What rom is on the phone?

*#*#4636#*#*
use this code and select umts etc.? its completely safe even if you select any option that doesn't make sense - you can always choose a different option.
