LG G8 T-Mobile signal issues - LG G8 Questions & Answers

Hi,
I would really appreciate if someone could help me with my LG G8.
I bought it off ebay , the phone is on T-Mobile version running Android 10 with the software version G820TM20i .
Since the phone was not available to buy in UK, i've ordered it from US .
I am using it with a EE sim card which is supposed to have the best network coverage in UK , but still the signal bar only shows 1 or 2 lines from 5 ( 5 being max strength ) .
When using the SIM card with another phone ( S10+ ) originally bought from UK I am not having any signal issues.
My question is : Could this be a problem with the stock ROM being a US version ?
I am thinking of flashing another ROM probably one from Europe or even UK, but unfortunatelly I don't know which one is the best.
Could anyone advise me ?
Thanks.

I have the same issues. Mine is a factory unlocked G820QM (US version).
Not working well in Singapore.
On the network with the best coverage just 2 bars and just UMTS.
With another network 3 bars and LTE but ... no mobile data.
Not easy getting these US phones to work overseas ...

It should be easy, i used to flash my lg g6 and lg g4 with ROMs in order to fix this kind of issues, with the help of the DEVs from here.
It's so sad that this forum is no longer that active like it used to be .

The G6 and G7 was also sold in Europe, SEA and so on. So flashing to other locations would be possible.
The G8 was only sold in the US, Korea and Canada. Still possible to flash to be able to work in the UK?

[Q] LG G3 Dual Sim Variants

Hello,
I been looking for the perfect LG G3 Dual Sim model in terms of Specs..
and since i found more than one model.. D856 , D857, D858 and D859
can anyone help me figure out what is are the differences among them ?
thank u
Hi
I've just ordered the D856 which for me (being based in the UK) is the better option considering that includes the LTE 800 band. I know the D858 does not include this band but I'm not entirely sure about the other two variants.

Hi c1181427,
I'm interested in getting a dual sim LG G3, also based in the UK. I'm currently on Vodafone so the D856 would be the ideal version. Can I ask where you ordered your D856 from?
Thanks in advance,

D858HK would work fine on Vodafone as well as it has band 2600 which is LTE+ used by Vodafone UK
Hi.I got mine from a website called from.ae they are based in UAE and the phone was delivered in five days.
Tbh I still haven't worked out the difference between the d856 and d858
One thing I noticed is that on mine there's barely any LG app installed (I think 2) which is surprising coming from a Samsung s4...Not sure if this is standard on LG phones or it's just this version

Hi c1181427,
Thanks for the info, I'll look into it now. Did you have to pay any customs on the phone?
Samsul,
Thanks but I live in Aberdeen, and work just outside the city. The 800mhz frequency already has poor coverage and so I don't even want to think about how little I will see 4G speeds if I am restricted to only the 2600mhz frequency. I'm not actually sure the 2600mhz frequency is in operation here anyway.

hi guys, my D856 has no LG apps pre-installed and it came with Google Play already installed. is this the case with the other dual sim variants too?
how much free RAM do you get on your G3's?

Hi guys, I bought a 858HK and it does not have the 800Mhz for 4G in UK
I also got slapped on import duty by £80
so the phone cost me £460
I am willing to sell if anyone wants it
Its a beautiful phone, very fast, the DUAL SIM is essential for work and personal and it comes with some LG apps that are much better than all my previous HTC phones
I've also had to pay £80 import duty but luckily the phone cost me a bit less
I was also hoping to get LTE 800 with my D856 (as advertized in the official LG spec sheet) but nothing...luckily LTE still works with my 3 UK SIM

Not sure if that's the case...
Got one 858HK yesterday, and so far it doesn't want to do 4G on my Vodafone UK SIM even though it does 2600MHz.
Spoken to Vodafone support and the lady who did not have much clue about the subject, could not confirm if vodafone uses both 800 and 2600, she was saying that in the UK it is only 800Mhz for LTE which is a bit odd and doesn't tie up with information provided here:
Code:
http://www.4g.co.uk/4g-frequencies-uk-need-know/
https://en.wikipedia.org/wiki/Vodafone_UK
On the wikipedia it says "LTE Advance" any body has an idea what that is?
The other thing is that the phone could be faulty as well. Need to try the EE SIM somewhere as that should be on 1800 and 2600Mhz.......
Edit: Apparently Voda UK does 2.6GHz in big agglomerations such as London, Birmingham, Manchester.... (this is not officially confirmed)

LG G3 D850 works On LTE In India & Middle East

Dear Sir,
I am going to Purchase LG G3 D850 US Version , Please Guide me Whether It works on 4G LTE and other networks in India or Middle east, Because i am an Indian while i am residing in Qatar.
Please help me i could purchase the Specified Model.
Awaiting your valued Reply....
Well, the D850 is a manufacturer _locked_ device that will work on that AT&T network only, in USA, unless you unlock it. Moreover, by design, the device supports out of factory only the radio bands that are necessary to operate on the AT&T network. Even if you manage to unlock the device to operate on non-ATT network, you still will run into issues with some bands missing. So personally, I wouldn't bother with the buying the D850 to use outside of USA or ATT network.. unless you have some solid proof that the D850 can be easily adapted to some other environment. I don't know abour Qatar, but I heard that the new Oneplus X smartphone is fairly optimal for using in India, and perhaps other countries. It has the same hardware specs as the G3.

Getting a new M8.. Help needed

Dear all,
I am living in India and I'm planning to buy an M8. Since the phone is officially not available anymore, I am getting one from eBay, which is a US imported one. [ Linky ].
Though the seller is saying that 4G is working for Indian SIMs, I am a bit suspicious. I am using Airtel 4G SIM ATM and am planning to root/install new ROMs. Suppose if the phone supports 4G initially and after flashing ROM will it affect the bands? How do I find that out?
Any help is appreciated.
flashing roms won't touch the radio ( the bands that device supports ) it will be intact
so if the stock out of the box status support your carrier network then any rom will work just fine

Thanks mate. I believe the seller himself has worked around with ROMs to make the 4G work. If I flash a new ROM it won't kill the phone right?

Flashing rom doesnt change the LTE band . If its US imported phone then IMO only verizon supports indain LTE band . Even that model only supports one band not all and m8 is not volte supported . Airtel calling will be fine as it use rollback to 3g for calling .
I am from india too . Market price for 4g m8 is about 10 k . These phone (mostly) are not new , they are refurbished . I have bought 5 m8 from ebay .
Hit THANKS if somebody help you

Thanks for the reply mate. I don't care about refurbished ones, as I am buying this only for the audio. Could you please tell me how to identify a 'refurbished' phone?

Check sim slot..it will be of different colour as comaperd to housing .
Match imei on sim slot, box and phone real. All should be same.
Charging port/ audio jack should be in new condtion, no used sign in there .
No quality seal ( i have seen some white seal on refurbished) .
Bootloader menu ( should be s-on and locked ) . If opened or used then it will tempered as all varaint comes as international unlock so need for software programming.
Hit THANKS if somebody help you
Additionally, if it is the Verizon version, it will possibly have the back cover replaced. Verizon version M8 has the Verizon logo on the back like this, which when resold as "unbranded, etc." will have the back cover replaced with one without any carrier logo.
In this case, the model number on the back will often not match what is shown in fastboot getvar all.

Is Sprint LG G8 factory unlocked for overseas GSM networks?

I am in the market for this phone and what I see most often is the Sprint variant. Some say unlocked, while some do not say. Are all Sprint LG G8 unlocked for overseas GSM networks? I am in Nigeria and have bought unlocked phones which worked fine here. I have also bought some that I unlocked myself and they also worked well her. The issue is that I have not seen any unlock service for the Sprint variant. There are services that unlock the Sprint G7 remotely, but none for the G8 yet. What should I do in this case? If the Sprint G8 is GSM unlocked for overseas use then I am fine with it. If not, and there is no way to unlock it yet, then I'm in a pickle. Your advice please.
Thanks.
Im currently in the caribbean using a sprint unlocked lg g8 from the seller yyywireless in ebay , the phone works great! although it hass two compromises
1- The apn settings are a little weird to configure , you have to reset the apn settings until you get them working
2-The phone is stuck in android 9 , april 2019 security patch , some people were able to update , but I cant
With that said , it shoud work in theory , try to look up the bands that your cellphone companies use and check if the sprint version has them.
Good luck!
