Hello !
I m using LG G2 Model D803.
I try to connect 3G but i could not.
I checked and i am in 3G zone, my APN is correct as per Mobile service provider.
After alot of searching on internet and reading threads and blogs,
i came to know about 3845#*803#, from where i went into hidden menu --> WCDMA only --> Modem Settings --> Network Mode.
And i found that the default band of WCDMA is 850 Mhz, while the service provider here in my region have WCDMA band of 2100 Mhz.
Therefore i want to know how to change the default band of WCDMA from 850 Mhz to 2100 Mhz.
Another thing, which i am not sure about is when i select only WCDMA or HSPA, my mobile signals gone (zero) !!!
Is this the reason of having the default WCDMA at 850 Mhz and service provider is providing 2100 Mhz.
I am really confused.
Please help me !!!
I have attached the screen shot of hidden setting where the WCDMA is 850 Mhz.
still waiting for reply ?

I bought an European Optimus 7 and it shows on the box "WCDMA 900/1900/2100, GSM850/900/1800/1900"
There's any way to put this phone to work on 3G WCDMA 850 networks at full speed?
Thanks
I own a Telus version of Optimus 7. My phone has the 900 3G band on it. I will tell you how to check whether your modem supports 850 or not. First, you open up the dialer and enter ##634#. This will install the MFG app, that will be accessible through your app list. The password that it asks is 277634#*#. Now you have access to the manufacturer test/setting menu. Proceed to the Engineer Menu, and then Modem Setting, followed by Band setting. There, you should see all the bands that are available, and WCMDA basically means UTMS or 3G. If you have the 850 band, it should be available in this menu. There are two other things you need to do before gaining access to this band, if available. But in order for me to continue, I need to know which carrier you plan to use this phone on. I am going to assume you want to use this in North America and you have already unlocked it. Let me know, and I shall help you further on making your phone functional for a 3G connection. BTW, I am typing this on my Optimus 7...the keyboard is seriously great, and if it wasn't for the loose buttons, I would have absolutely no regret over my purchase.
Thanks.
I saw here, there are these options available:
1.Automatic
2.WCDMA Only
3.GSM Only
4.WCDMA 850
5.WCDMA 1900
6.WCDMA 2100
7.GSM 850
8.GSM 900
9.GSM 1800
10.GSM 1900
11.WCDMA 900
Sorry for picking up this old thread again but there is no final answer on this.
The point is that I'm having the same problem, I have a european E900 and I can see the WCDMA 850 in the MFG settings. So is this working?
I'm going to Thailand next week and wanted to use True Move 3G which is on 850 Mhz.
Ok, just for the record - I am in Thailand now and the 850Mhz 3G Network from True Move is not working on the European E900.
Hope this helps for those who were looking for this answer.
Hello
I don't see this tips for the ativ s and i want share it ... for me it's great... because my phone in canada ( the lte model t899 ) and all others phone always connect to the 1900 mhz band in my area... ( the 850 mhz is available but network setting prefer 1900 mhz )
When i am connected the 850 mhz band i get great signal 3 bar ( i don't want talk db ) - vs 1 bar on 1900 ...
For this reason i like to switch to 850 mhz only... this feature miss me on phone i can't select the band...
This solution is great in some area in usa too... where tmobile is present by exemple... for people who want force to use the 1900 mhz band instead the 1700 aws band... ( some people say you get better speed on 1900 mhz where 1900 mhz is avaible for tmobile )

You go to diagnostic mode
*#0011#
You see the signal in DB here ;p
Press on the screen the back ... then 1.... you are in the umts main menu...
Go to 1 => 8 => 7 => 2 =>
Select 1 for automatic (default setting)...
2 for your own umts/hspa/wcdma band and to force in 3g ... i choose 850 mhz here for me ;p you can choose wcdma all to force your samsung on 3G only !
3 for gsm ...
4 for lte ...
to revert in default setting... just put in automatic...
the setting is not erased when you reboot your phone...
Don't go to any others menu if you don't have any idea what is this !
I don't take any responsability if you fxxx your phone !
For sure this tips work for the international version too
Enjoy and have a nice day !
( PS : if you have or go from a samsung s3/s4 or others samsung you see this menu in many others phone and there are some tweaks on this phone you can unlock for free... my phone is unlocked... i can't test if via this menu you can unlock the phone for free )

This uses the diagnostic dialer, so please take a moment and reply over here. Also can you show us some screenshots?
This worked on my Samsung Omnia 7 too. Symbian had UMTS only setting, WP should have that too.

Did you find solution? I have same issue not connecting to 900mhz 3g
Hi,
I found OPO ONE + tutorial about adding LTE BAND in Qualcomm device and i want to make the same thing with my LG F320K.
I try to add GSM and 3G BAND by putting 844425030534016 in 1877 nv value with QSDM but when i start QPST software
downloader it didn't show me a change after a reboot. I try to change this value with QPST Software Downloader and i ve got this error: NV_IMEI_SV, that don't allow me to make the change.
I want to add LTE B20 800Mhz but cannot.
Can someone give me the Qcn backup of an international D802 or help me to activate all necessary network in my country (France)?
Thanks a lot, best regards.
844425030534016 with mzTool gave me:
[Bit_07] GSM DCS 1800 band
[Bit_08] GSM Extended GSM (E-GSM) band
[Bit_09] GSM Primary GSM (P-GSM) band
[Bit_18] GSM 750 band
[Bit_19] GSM 850 band
[Bit_20] GSM Railways GSM 900 Band
[Bit_21] GSM PCS 1900 band
[Bit_22] WCDMA Band I - EUROPE JAPAN & CHINA IMT 2100 band
[Bit_23] WCDMA Band II - US PCS 1900 band
[Bit_24] WCDMA Band III - EUROPE & CHINA DCS 1800 band
[Bit_26] WCDMA Band V - US 850 band
[Bit_48] WCDMA Band VII - EUROPE 2600 band
[Bit_49] WCDMA Band VIII - EUROPE & JAPAN 900 band
These TMobile/Metro devices (SM-G530T AND SM-G530T1) seem to have the WCDMA 900 band blocked or disabled.
Is there any way to enable the WCDMA 900 (3G) band ? I've seem this done for other Samsung Device mostly in the EU.
