I was recently in Korea for work, so I picked up the G4 to bring back to the US. I bought it from SK Telecom, they told me phone should work globally. Now being back in the US, i popped in my Verizon Sim card and no mobile network is available. Phone is reading my sim and has the correct APNs, but still no connection. Does anyone know how to access the service menu to change bands?

I figured, but does anyone know how to access the hidden menu to view all the bands available?
5457#*500#
That should do however I can't access the main hidden menu to disable the throttling.
Thanks for the info 3rd degree.
I tried that on my H815 G4 but it didn't work (invalid code).
I also tried 5457#*815# but that didn't work either.
Unfortunately the 3845#*modelnumber# that always worked previously doesn't now. eg 3845#*815# just gives the invalid code error.
*Edit* the answer is in this thread:
http://forum.xda-developers.com/g4/help/how-to-enter-g4-hidden-menu-t3122373
the code that works for me is 277634#*#

For some reason, field test isn't an option on my Tmo variant. Any ideas? (i'm trying to see what LTE bands are enabled)
anyone knows the marshmallow code?

Hello all,
Prior to going to the US last September I had checked with my carrier (Vivo) in Brazil that the 4G-LTE frquency they use is 2.600MHz. When in the US, I managed to buy the above said device and brought home. Back home, as it was
unlocked my carrier's SIM card worked like a charm. It downloaded from the carrier's network the APN configurations and all was fine.
I went to the carrier's shop to try the 4G-LTE so I could bump up my contract. I tried the clerk's SIM card (he has 4G-LTE) and the signal icon changed from 4G to a smaller 4G with underscore LTE. But only the 3G and 2G APNs were found when searching networks manually.
I did rooted the device and removed the bloatware that came along using this xda-developers how-to.
Any idea how can I get 4G-LTE access on my device?
Thanks in advance,
gtludwig

I suspect your APN need modifying. Check the clerks APN settings against yours.
Your APN is set wrong. I'm not sure how to change it on the stock AT&T ROM though.

It's in the settings/tethering and networks/mobile networks/access point names. I have consumer cellular, but it leases from ATT, so it has slightly different settings, though ATT APN will work ok.

I had thought that menu was just tethering settings. That's embarrassing. :S
Hi, I have a LG G4 H818N LTE model with dual sim running firmware v10c.
According to the mobile carrier, they support 900MHz and 2100MHz, yet I am unable to obtain 4G connection on my phone. I have enabled the option in the sim settings for "4G/3G/2G" on the SIM that I want to use for data and set that sim as the sim to use for data connection but it still only connects at H+.
Perhaps the carrier is using Cat 6 LTE. Is there a way to enable Cat 6 LTE on the H818N?
Is there a way that I can test LTE connectivity on the phone or are there perhaps any settings that I may have missed to force LTE connection?
I previously had an LG G3 D855 which connected to 4G without any issues.
Is there a file where I can manually edit the 4G bands for my phone?
Finally, slightly off topic. Can anyone explain to me what a KDZ file is?
Assistance would be highly appreciated. Thanks.
mine has a working LTE on both sim 1 and sim 2 but not simultaneously. i found out that the apn is alittle bit buggy. check your apn and set the primary.
Thanks, would you mind walking me through the steps that you followed please?

Hi all, thank you so much for the answer. I'm actually having the same problem with my LG G4 H818N. I'd be grateful if anyone can advise what kind of setting I should choose for my phone to work on Vodafone UK 4G network. I'm so frustrated to pay 4G plan but only get up to H+

Can't provide link as using xda app, but Google 'wiki Europe lte bands' and it should come up with what you want. I'm on three UK and there was two different bands to try, turned out to be band 3 for me. Hope this helps

Sorry for my late reply! I did Google however, Vodafone is on Band 20. When I choose this option, it said Fail. Is anyone know why?

Thanks. I just tried in the FieldTest -> Network Mode-> set SIM 2 to GSM 850 and try Band 20 again under the LTE Band Selection, but still Fail.
Are these steps correct?

However, I only have 1 SIM inserted at the moment. In order to change to Band 20, does it need to have 2 SIMs inserted and follow your instruction?

I'm having a similar issue with my 818N. I can't get 4G/LTE.
Has anyone worked out why or how to fix it?
The hidden menus don't allow me to select lte bands they all just say fail after I select them.
In the RAT menu I am unable to select LTE only, it also fails.
It's as if LTE is disabled?
I tried installing 818P software into the phone which worked fine however I still couldn't connect to 4G.
I give up
It turns out that my phone was faulty and I've returned it to HK for a full refund. DWI were good to deal with and were fast to refund me my money once they confirmed that it was DOA.
I have an LG G5 LS992 from Sprint. I bought that phone in the USA. Now I need to use it in Spain. Sprint said they unlocked the phone. I am using Vodafone carrier. When I inserted the SIM card, Vodafone ES is recognized. I can do and receive calls, but I do not have internet. Any solution to that problem?

Hi, thanks.
Yes, I have done a new APN and is still not working.
I also tried the different options in the submenu System Selection. Also, I enabled all possible bands in the Hidden Menu.
I have G710EAW (LG G7+) which has by default active LTE Bands 1,3,5,7,8,28. However I live in Europe and I with my carrier I would benefit from band 20 as well.
What I am doing currently, is via service menu I am activating manually all the bands I need (including band 20) in modem settings. This works perfectly fine, actually I am so used to it I can do it within seconds. Naturally after phone restart all is reverted.
It is a minor inconvenience, hence the question: any idea how to make the setting persistent or any tool that would do it after each reboot?
I would like to avoid installing firmware from other model (if that's even possible, I am layman in this...)

I don't know if Tasker needs root but you may be able to accomplish it with Tasker.
Although it may be a pain to setup i think tasker has a subreddit that you may be able to ask somebody who uses it more than I do

Hi, I'm also looking to buy the EAW version for the dual sim feature. So you confirm the phone has all the LTE bands but some of them are locked by the software installed?
I need a phone dual sim that works in Europe and USA....

Well I do believe Qualcomm Snapdragon is an excellent platform and the build-in modem is capable of all bands. I do have EAW version (I think originally from Hong Kong).
The band selection is not available from OS, but if you dial *#546368#*710# there is a hidden menu where in
Field Test -> Modem Settings -> LTE Band Selection I have these bands available:
1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,38,40
To my limited experience any combination works just fine (I am in central EU). The drawback is that after reboot (or airplane mode) only the default (1,3,5,7,8,28) are on.
Just for the hell of it. I tried on my US phone, can't even access the menu Sucks.

It works for me on the T-Mobile variant you have to use the stock lg dialer and type the code in you cant just copy it in
How do you know this has worked? I toggled on the bands that I need bu there was no 'success' or save prompt and if I exit and re-do the process all the boxes are un-ticked when I navigate to the LTE bands page.
