Hi, according to what i've read the radio should be choosen to the country and the carrier you're working with, I live in colombia and my carrier is movistar, but im not getting 3g speeds, i just bought a t-mobile g2, i've seen that carriers in colombia are working on UMTS 850 and UMTS 1900, so can anyone help me on choosing the correct radio to my phone?
THANKS!!!!
The 3G bands on the G2 are 1700/2100 and 2100 MHz, so you are never going to get 3G speeds on it, if your network is using 850 and 1900 MHz. This is set in hardware, and can't be changed by flashing radios. So you are stuck on EDGE. You bought the wrong model of the Vision if you want 3G on your network. The only version with compatibility with 850 and 1900 MHz 3G bands is the Bell Canada version of the Desire Z.
Can anyone confirm if the Band Selection menu is available. It's critical for me being on Bell's swiss cheese network to be able to manually select a band to get service in a particular area. Otherwise I'll need to wait an extra month and go with Rogers.
I don't understand what you mean. The phone's compatible only with Bell's 850/1900 HSPA bands. What other bands can you switch to?
Through the band selection menu you can choose to only use 850 and not have it search for 1900 constantly. In an area where 1900 doesn't penetrate very well it will intermittently fall back to 850 but will always continue to search for 1900 which leads to a lack of signal most of the time.

who said so?
The phone comes with a penta-band 3G chip which allows it to connect to any 3g network around the world.
I have Korean LG G Pro F240L
everything works alright except that it doesn't fully use it's 3g capabilities
I live in an area where 3G signal is not that stable, usually 2-4 bars, signal can drop for a few seconds every now and then, I use telstra in Australia, which use 850Mhz/2100Mhz 3G network (850 in most areas, 2100 only for extra coverage)
I set the network preference as Auto, the trouble is that most of the time the phone sticks to 2G/GPRS with small icon on the top showing "G",
and if I want to use 3g I have to go to the network setting and change it from auto to "WCDMA only", the network will change to 3g (icon on top showing 3g) with signal strength about 2-4 bars
obviously with unstable 3g signals I can't keep it "WCDMA only" all the time, so I have to change it back to auto.
once it's in auto the phone will not revert to GPRS straightaway, it will keep going with 3g for a while and then if there is a drop of 3g signal it will then change to 2g/gprs and stay that way.
is there anyway to set the phone in "3g preferred" state where 3g is utilized automaticly whenever the internet is needed? (as far as I know, no such option exists).
do you have any trouble with your 3g settings? please share, thanks
I have discovered something new
in the hidden menu-WCDMA service menu-GSM/WCDMA band, when you click on WCDMA 1900 and WCDMA 2100, it shows success, whereas when you click on WCDMA 850 it displays fail
it seems that the phone is not using the stable 850 band at all, rather it relies on the 2100 band, this explains the erratic signal strength
I did a bit more digging
the band frequency for korean providers are
SK (S) 2G (CDMA) 800, 3G (UMTS/HSPA) 2100, 4G (LTE) 850/1800
LG U+ (L) no 2G, 3G (CDMA/EVDO)1800, 4G (LTE) 850/2100
KT (K) no 2G, 3G (UMTS/HSPA) 2100, 4G (LTE) 850/900/1800
also
telstra 2G (GSM/EDGE) 900/1800, 2G (UMTS/WCDMA/HSPA) 850 (main 99% population) /2100 (minor), 4G (LTE) 1800
AT&T (E980) 2G(GSM/GPRS/EDGE) 850/1900, 3G(UMTS/HSPA) 850/1900
strange that there doesn't seem to be direct connection/conflict between telstra bands and the LG U+ bands, i.e. if my F240L is able to use GSM and WCDMA 2100, why not WCDMA 850
I believe G pro is a global phone that supports all communication standards
I am unsure about the root of the problem, is it the matter of settings (i.e. can be solved by tweaking the service menu), or the problem of incompatible radio (hence can be solved by flashing appropriate radio)
also is there anyway to tell the band frequency the phone is using? I did my search and nothing yielded, I believe there is no such solution
my question comes down to how to enable/unlock 850 band on this phone?
If you use AT&T and have a korean phone, do you have similar problem? (as shown above AT&T partly relies on 850 band as well)
also if i guess right the problem is not limited to LG G Pro, any LG Korean phone potentially will have similar issues, I tried search optimus G forum but nothing turned up.
Same problem, korean phone wrong band

I got mine yesterday and have the same problem. Is it possible to select the band? mine is the SK version and I need to work with the AT&T band, can I just flash a new radio band? How do I get to the hidden menu?
Thanks!
I have kind of same problem with my f240
i guess if the at&t stock rom could resolve those problems
edit:

no
I have since learned that basebands are all hardware encoded, at least for LG phones, and there is no way to enable WCDMA 850 band if it is not originally supported by the phone, flashing the radio will not change the hardware capability of the phone
The Korean LG G pro supports only
2G : 850/900/1800/1900 MHz
3G : 900/2100 MHz
4G, LTE: F240K - 900/1800 MHz (Band 8 & 3) F240S - 850/1800 MHz (Band 5 & 3), F240L - 850/2100 MHz (Band 5 & 1)
I have since change the network provider (who provides 3G on 2100 band), it's not ideal but it's the only solution for me
pls correct my if I am wrong
i have LU6200
inside my house 3G is suck, so i use GSM Only mode, but i only get G signal which mean GPRS i think and it is very slow. How to enable 2G/EDGE so i can get faster internet than GPRS?
Hi, I have F240k the 3G over 900 Mhz band is imposible.. I dont know if my phone is broken or I need flash with any new Kernel or something.. if any one can help to me would be very apreciate
3G over 2100Mhz is nice.
Gprs over 900 Mhz work fine but very very slow.
thank in advance

Hi I also have F240K from a week. I can't managed sim to work. Don't have any signal 2G/3G.
I tried most of the methods described here without success (flashing Telcel and Korean rom after, E988HK baseband, changing every setting in the service menu)
Which baseband do you use?
I can't use my new phone and I'm so desperate ;/
Hi, I sell my phone..really have seriously problem with the signal. I remenber that the best option was use the original rom...but anyway the signal was very bad. Sorry man.

Im in Australia, I cant even get my F240S/L to detect a sim. Ive tried telstra & optus sim.
it doesnt detect any sim.. any advice on what to do.
NOTE:

> with optus sim installed it can see some networks but doesnt connect, it also still says no sim installed.
> i tried to restore phone back to factory to update to kitkat, but can seem to get the LG phone software tool to work.
any advice?
have the same issue here in my f240l. i cant use my mobile internet, so slow and most of the time no connection even i have a strong signal. btw im from the country of Philippines. anyone can help me please?

Hi Bro,
I am facing same issue regarding Network. I am using stock Jelly Bean 4.1.2 LG G PRO F240L. My Cell is not Rooted
Please tell me what did you do regarding this issue ?
Unstable/Weak phone signals
Singles on my korean LG G Pro are very unstable and after every few minutes my phone shows "Emergency calls only" with an empty signal bar and then suddenly gets full signal back with in few seconds.
I am using custom Android 4.1.2
Same time my signals on my Xperia Z phone with same network remains stable at same place.
Is it a software issues ??
If yes then how I can resolve it ?
Please need your help

Your expertise required in this regard.
Hi,
Just brought a I9082L in Thailand.
Soon i will be moving to The Netherlands but the I9082L supports 850mhz 3g wile i need 900Mhz 3g over there.
Can i just flash the stock I9082 rom/modem to get 900Mhz or is it a hardware limitation?
Thanks for ur help

From what I know i9082 supports both 850 and 900 upto 2G as well as 3G. But the 3G support is restricted to SIM slot 1.
SIM1
Cellular Networks: GSM 850/900/1800/1900, UMTS 850/900/1900/2100
Data Networks: GPRS, EDGE, UMTS, HSDPA, HSUPA, HSPA+
SIM2
Cellular Networks: GSM 850/900/1800/1900
Data Networks: GPRS, EDGE
The "L" variant might have a restriction on 900MHz, but that's something you will to experiment with the modem of i9082.
Flashing i9082's modem on i9082L will do one of two things, either your 3G network will recognize the 900 frequency or it'll stop your 3G entirely. So it would probably be best if you keep your original i9082L firmware/modem with you for just in case.

Thanks for your response, I flashed the I9082 (I9082XXUBMF2 and I9082XXUBMJ3 Indian Version) modem but both resulted in a bootloop. flashed the old one back.
Never had a smartphone with sush restriction. a friend of mine has the normal I9082 not the L version and he is not able to receive 850mhz here.
Looks like many samsung “budget” phones have a 3g freq lock to 850 or 900. I hope its just the software and that a fix/workaround for that will come someday like they had for the I9000.
Hi All,
I got LG G3 D855 international version from eBay last week, I'm wondering if I can get LTE, or H+ network on the phone. On "Network Mode I can see "GSM/WCDMA/LTE auto" listed , when I choose it the signal bars on the notification area start looping, after that it switch back to "GSM/WCDMA" option !
I added a new APN for LTE , but still not working on LTE.
According to T-Mobile coverage map , my area is support 4G /LTE network . The phone is rooted , software version: V10b-GLOBAL-COM (For Hong Kong)
I can get 10-12MB download speed on H, I guessing it will be a way faster on H+ , or LTE.
Any idea about how to get LTE to work?
Thank you,
I'm surprised HSPA is even working, you must be in an area where they moved it to 1900 (Band 2). The D855 model doesn't support the AWS band, also known as Band 4 or the 1700 frequency (so says GSM Arena anyway) . This band is where T-Mobile has their primary network deployments these days. That means no HSPA+ (that's only on Band 4, not Band 2), and no LTE at all.
Bottom line is I don't think you want to be using the Euro D855 model on T-Mobile USA network. Not the right tool for the job.
Sent from my LG-V500 using Tapatalk
I think it should still work. Frequencies tmo supports (straight from website):
4G LTE : Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)
4G HSPA+: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
3G HSPA: Band 4 (1700/2100 MHz)
The phone supports 2100MHz and 700MHz, and not 1900 or 1700. I just did a speed test and get 4Mbps reporting it used HSPA+. If that works, I'm not sure why LTE wouldn't unless it *has* to have the 1700 to get LTE.
Edit: here's some info on the 700MHz band http://www.spectrumgateway.com/t-mobile-700a-spectrum. I'll try it when I'm on vacation. I live in NC unfortunately.
Hi, I use LG G3 D855 and looking for solution to get LTE on T-Mobile USA. After some research inside the forum, I decided to try to use CyanogenMod (CM 12.1) on my system.
It works well and now I can enjoy LTE on T-Mobile network, even though not pretty stable yet, but I am good with that since the OS still ongoing development.
You can try to download the OS on Cyanogen official website, and use the latest update available.
In order to confirm if you get LTE signal, beside check on your LTE sign, you can use LTE Discovery apps whenever you lost LTE connection and try to reconnect on an LTE signal.
Oh, forgot to mention, I am located in College Station, TX.
Beware: LTE Band 4 (1700/2100 combo) it's not the same LTE Band 1 (2100 only) that LG G3 D855 supports. Better talk using band numbers not frequencies.
