[Q] D802 in South Korea, No LTE on KT - G2 Q&A, Help & Troubleshooting

Hello everyone, I got a problem to ask. I've been visiting XDA ever since I use Galaxy ACE, so rooting, custom roms, etc. aren't a problem to me, but I'm NOT a developer.
I originally live in a country where there is no LTE and I'm now living in Korea for about 5 months, so this is the first time I got excited about experiencing LTE speed.
However, things didn't go well as I can't connect to the RAT: LTE network at all (it's connecting all well to WCDMA/GSM). I've been changing roms, trying several basebands, and editing build.prop (which soft-bricked my beast several days ago) and it's really frustrating. If I asked whether my SIM is LTE supported or not, I've got the "LTE WARP" edition or something-SIM, KT, prepaid. I didn't ask the details, though. I also searched beforehand which bands are provided by KT, which are 900 MHz (Band 8), and 1800 MHz (Band 3). Both are supported by D802.

LTE: Snapdragon can work with every Band doesn't matter Model/Zone - tested

Few days ago i ask help for enable LTE on a G900L (korean) specific baseband in my zone Europe (italy)
Someone answer about an hardware frequency limit for specific geographic zone.
Well as i suppose every qualcomm snapdragon chip mount the same LTE modem and can connect to every LTE band if unlocked.
So that there is just a software limitation not hardware.
I did right after a lot of try i found a way for make my phone G900L able to connect on italian LTE frequency. This also mean every model with a qualcomm snapdragon are able to connect on LTE in every zone
Attach some screenshot of my device as proof: last one (debug menu LTE) show witch band im using (band 3 1800 Mhz italy) instead of band 5 (850 Mhz) and band 1 (2100 Mhz LG U+ provider)

Band usage effect on battery life

i have searched for this alot online and havent found a clear answer. i am stuck between the two note 4 models (N910F and N910C). i have heard some rumors that if your phone doesnt support all the cell bands in your country it can result in battery drain. in my country (greece) the officially supported version is N910F (with the snapdragon) but i havent found which specific bands it supports. i know it will work cause some stores import it independantly and people have bought it but even if the difference will be 1 hour SoT i would like to know it. my countrys cell bands are 900, 1800 and 2100 Mhz. does anyone know which bands each model uses and whether picking the "wrong one" for my countrys network will result in a heaviest battery drain?
186 views but not 1 reply...seems like 186 ppl have no clue
They have the same bands....
They support the same bands, the diff. is that the N910F supports Cat.6 LTE (300mbps download) while the N910C supports Cat.4 LTE (150mbps download).
Here you go, straight from GSMArena:

Meizu Metal 3G and 4G connectivity not working

Hi Everybody,
I have bought Meizu Metal from Aliexpress and received it few days ago. Everything is working smoothly except the 3G and 4G connection. The system version is Flyme OS 5.1.2.0Y, YounOS version 3.1.6. The GSM network is working fine. The specifications of the phone clearly shows that it supports 3G and 4G networks : 4G FDD-LTE:Bands:B3,B1 , 3G WCDMA:900/1900/2100MHz. My local operators supports 2100mhz for 3G and B3 for 4G. The phone detects 3G and 4G connection , but when I try to start browser or any app that requires internet it fails to connect.

Have you set APN values? If you haven't, find out those values with your carrier.

Thank you. That was the problem. I set the APN values manually and it worked

For band 4,up 1710-1780 ,down 2110-2180 covers by the Band 1 range,so it's possible for hardware to support that with B1/B3 band channel.
for band 1 ,i dont think factory willing to re-design the B1/B3/B7 classical triple band hardware design with different PAM and LNA used.
for band 41,in redmi note 3 global the PA and LNA for Band 41 was reduced although it's possible to receive very strong signal from the BS station(put your phone on the antenna),but due to lack of PA,PUSCH was limited to QPSK,so for RN4,just have try~
And DO NOT ask me about band 20,DD800 need specific hardware duplex that may be reduced for the costs,it's only availiable on the 2016102 GLobal version.
So,detailed guides should be there.

[SM-G900F] Connected to GSM/WCDMA but it shows the "4G" icon

Hi everyone!
3 years ago, I purchased the Galaxy S5 (SM-G900F orignal) from Mobicom (Mongolia). The phone has the 4G LTE capability but it has some problems
1) I have a 4G LTE SIM card and a contract (and i'm near 4G LTE towers) but it doesn't connect to.
2)I set the network mode to GSM/WCDMA/LTE (auto connect) but still not showing LTE.
3) "Network type" shows EDGE/UMTS/HSPA not LTE, but my display shows 4G (confusing)
Is there any problems with my phone itself? How i can fix that?
Here is my screenshot:

I don't have this variant but, your best bet is to post this question within the following Q&A thread that's specific to your device and variants.

Good Luck!
