Korean Optimus G Bands - LG Optimus G (International)

Hi, I am in Korea right now. I want to get a cell phone that I can bring back to Canada when I leave in a few months.
Right now, I have the Vega Racer 2, and it'll only run on my provider back home on 2G (Rogers).
I can't seem to get the right information, so I was wondering if you guys knew what bands the Korean variants of the G has.
From research, it seems that only the S3 has quad-band 2G/3G bands. But I had a S3 back home, and that white Optimus G is mighty beautiful and exotic (they don't have the white model outside of Korea).
Thanks!

Optimus G is Quad Band 3G. The only difference is the LTE frequencies it supports, for example the one I have runs on 700/1700/2100 which is valid for Virgin Mobile Canada, Bell, Telus and Sasktel.

Thanks!

But from http://pdadb.net/index.php?m=specs&id=4127&c=lg_f180k_optimus_g_lg_gee there only Cellular:Networks: GSM900, GSM1800, GSM1900, UMTS2100 (B1)

Well, my info is from the phone itself
Also i see no difference

Tim4, I have F180K, and It's not working in WCDMA 900. I tried with Korean ROM, CM 10.1, my friends made tests with EU ROM+ korean baseband - so, I suppose you didin't try it...

Ofcourse im not, im using LTE 1800.
The freqs i wrote here are from network settings of F180K, try to it set as 900mhz, not an auto.
To enter network settings you have to input secret menu code, which i dont remember anymore, google it.
Also note that E975 stock rom doesnt have the hidden network settings (Or the code is different), only stock F180K rom has one.

I was testing it, and as i remember, (in stock Korean ROM) band 900 refers to GSM, same in CM 10.1

Does anyone know the secret code for the service menu as i am also trying to get my korean phone phone to work on 2100 or 2600 lte.
Thanks

[Q] Who works E250 modem/RIL port to N7105?

I have N7105 LTE model in Korea.
But Korea SKTelecom LTE band is 850/1800. Major LTE band is 850, sub band is 1800
All know that N7105 default LTE band is 800/1800/2600
So i want to flash E250 modem to my N7105.
(Just modem only flashing, because korean mobile operators are too many customized. I hate it.)
How can I E250S modem flash on my N7105?
Hopefully you get a decent advise, as i on the other hand have a E250 purchased in Taiwan, and would like to flash it to N7105 as reception in Canada with the current setup is horrible and LTE don't seem to work.

Oh, dears
Thanks for your reply and i know your pain.
LTE band problem is i know that Canada LTE use 1700/2100/2600.
So, if your carrier using 2600(Rogers) you will use only 2600, other LTE band 1700/2100 is not recognized your E250 on 7105 ROM.
Because N7105 only support 800/1800/2600 bands.(E250s is support just two bands, 850/1800)
Thanks

I wasn't aware of this when i was buying the phone ((((
On top of that, when i did the latest update i bricked/wiped all settings for the N7105, none of the ROMs through ODIN would take (i would get a FAIL message)i had to do Kies factory update which reverted the phone to E250.
Many of the ROMs would not be accepted by the phone, even after ROOTing. Still trying to get it on the acceptable level as the SKT setup gave me very poor reception.
Is there a way to change the modem operating frequencies by adding a ROGERS modem for example?

[Q] LG G pro 3G issues

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:
service menu:
5457#*240#
hidden menu:

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.

help with LTE for an e975 on FIDO (2600)

I have a Korean e975 that is supposed to be able to operate its LTE at 2600. I am currently with FIDO (Canada) and have the correct LTE APN (and LTE sim) and I know that FIDO operates its LTE service at 2100 and 2600. I can currently only get 3G and H but no 4G speeds. I have asked FIDO to reset my account but it did not solve the problem. Any help would be greatly appreciated!
Thanks in advance.

If it has got the extandable antenna on the side (meant to receive tv brodcasts in Korea) it is the Korean version, no matter what is written in the smartphone infos. And since it is a korean version is able to operate only with 850mhz(f180l) , 1800Mhz(f180k) LTE. For the korean version there are no 2600 mhz Lte capabilities,sorry
Only E971, E976 and E977 have 2600mhz.
Ok....thanks for the info....bummer!
Is the extendable antenna useful for anything in canada? Thanks
Where are you going to plug in an extendable antenna?

AT&T 2G/3G WorldWide [SOLVED]

Guys,
I bought an E980 (AT&T) and brought to brazil, unlocked it and its working great except for 2G/3G, just doesn't connect, I checked the frequencies and it's a match, my mobile operator (Claro) uses GSM 850-2G/2100-3G, are there any configurations/tests/flashings I can do for it to work?
G Pro - http://www.gsmarena.com/lg_optimus_g_pro_e985-5254.php
Thanks.
Sorry, meant to post in Q&A, Help & Troubleshooting.
One correction, my operator uses 1900 while AT&T 2100, but E980 is capable of 1900, I think it come disabled, can I activate it somewhere? Thanks.
AT&T doesn't use 2100Mhz. They use 850Mhz and 1900Mhz. 2100Mhz is mostly international like Asia and Europe. Check APN setting and also check *#*#4636#*#* if you're able to switch to HSPA/EDGE.

Thanks for the answer cpro, but the solution was actually alot easier, I was configuring the APN as a VPN, after gotting it right it's working like a charm, 5MBPs downlink.

[Q] E975 3G connectivity

I just bought a Optimus G E975 that operates with only 3G(HSDPA): 900, 2100 MHz frequencies. I'm currently on the Telstra network that only provides 850, 2100MHz frequencies for 3G. The 2100MHz is available in locations where there is high volumes of usage (city for example) but I'm never in these locations when using my phone so it's resorting to 2G connectivity.
Is there anything I can do to make the E975 compatible? or is it the case of the antenna design and therefore I'll have to change phones?
Note: I didn't know at the time of purchase but Australia has a LG Optimus G E975k designed (850MHZ, 2100 MHz for 3G) for the networks we have here.

After emailing the supplier about my issue, they suggested trying a new sim card. Could this be a real possibility?
Below is the message they sent after I informed them of the issue:
2G(GSM): 850,900,1800,1900,
3G(UMTS): N/A
3G(HSDPA): 900,2100, (not Next G
It should be related to the network APN settings. Also, it may due to your sim card problem, as this phone need to use new sim card.
Please contact your sim card service provider to change the new sim card, it is free of charge.
For the APN settings, you can go to settings, mobile network, ,then access point name (APN). Then you can click your service provider, then select APN. Then you can change the APN link according to your sevice provider official link
Thanks for your good communication
Please keep in touch, as i believe everything can be solved through communication

According to the official LG website and many others, the hardware only supports 900 MHz and 2100 MHz frequency on a 3G network. I wish what you were saying was true .
I tried flashing E975k firmware (i'm assuming it would install a e975k baseband modem) but I still couldn't connect to 3G. So it must be due to the antenna design.
I appreciate the response.
rogers(canada) also uses 850 mhz ...so maybe asking for an e971/973(forgot which one is bell,which one is rogers) modem??
are you suggesting to flash the e973 firmware since it has the 850MHz baseband modem? I've been flashing all e975 software.. havnt tried e973 yet
You will have 8 mpx camera instead of 13 mpx if you flash the e973 firmware but maybe you will solve your connectivity issues
I said modem only,not whole rom.

I tried flashing a few modems "basebands" From the 977 Venezuela, also a f1800 modem and no go... my Phone its a E975 int. Flash Open Europe Firmware then the Modem of a 977 and no go...
Is there a work around or something to get 3g on this phone? "Movistar Venezuela"
3g problem
The phone won t stay connected on 3g. I start the data connection, 3g, but after a some time the connection stop all by itself with no posibility to turn on again. Only restarting will help, but ,again after a while same problem. The only pisibility to turn the connection on is only by restarting the phone. When i switch the 2g connection there s no problem. Thanks
