I unlocked my SGH-i337 and used sim cards in Thailand and Burma. No problem with reception.
Check the wireless bands use in Parkistan and play around with your network setting.
its GSM900 here and config screen shows GSM 900 available tried all network settings .. only GSM gsm and LTE etc...

Where are you at? Which network? There are areas (rare but there are) where t-mobile is wcdma (3g) only.

Well if your APN settings are allright you either have no LTE coverage or it isn`t available at your provider. LTE should be activated automaticaly if available.

my APN setting is right and i am in LTE coverage (my galaxy s3 9305 has LTE/WCDMA/GSM mode and connect to LTE network) but it has not any LTE in setting and i cant connect to LTE
I update to G900FDXXU1ANH2 to resolve this problem but it doesnt resolved

Better contact your provider. Does the G900FD support your providers LTE band/frequency? I would check that first.

i think that i have to see LTE in networks if there is no sim card registered in the phone
am i right ?

That would be impossible as you cannot connect to the network without a simcard

I`am starting to think that the G900FD supports different LTE bands then the G900F because it is build for a different region. Its mainly sold in the far east as i can see so far. Better Google to find the specs and the phones supported LTE bands. You may not be able to get LTE with your device i`am afraid. Good luck mate.

you are right
i have to check frequency bands in my phone becuse i buy this phone from UAE and i dont know that LTE bands are the same as my operators lte frequency bands
You should see LTE on sim2 only. Not Sim 1 .

Similar problem with me, could anybody share some insight
Hi guys
I also had the issue of LTE not being selectable on my S5 Duos - here's my experiences.
Firstly I tried putting another carriers SIM into the phone, and noticed that LTE -was- selectable, but upon putting my own SIM back in, it again wasn't. HOWEVER - after putting my own SIM back in after using LTE on the other SIM, the phone automatically connected to LTE/4G even though WCDMA (auto) was selected! Very odd.
To permanently fix this here was my method -
My phone was shipped with ANF7 firmware, which was patched to overcome the kernel vulnerability Towelroot uses to gain root. I flashed my phone with ODIN back to ANF6 firmware, applied towelroot V3, then installed root browser and edited the system file data >property>persist.radio.lteon and changed the value from false to true, and rebooted the phone. LTE is now selectable!
:EDIT: Upgrading again to ANF7 broke the selection, but it still connected to LTE automatically... So odd.

Hi,
I had the same issue as yours. You can either fix it by a method explained here at XDA and it involves rooting the device. However I fixed my issue by flashing the latest firmware "G900FDXXU1ANJ2" for the month of November via Odin and now I can see the LTE/WCDMA/GSM option on sim 1. Hope this helps
I have GSM Unlocked Samsung l720 , currently its running 4.4.2 with base band VPUFNG2.
I have having good GSM signal out door , but indoor my GSM signal level gets under a lot of fluctuation and even goes to no network signal multiple times in a day.
I have tried other network sim cards as well , but the problem remains the same, while network signal on my other mobiles at the same location are up to mark.
I need help on it , if there is any flash-able modem file which can make my gsm signal stronger , also is it possible to flash i9500 modem file on l720.
Thanks in advance.
Hello.
I have a note 3 n9005 and when the network mode is WCDMA/GSM or LTE/WCDMA/GSM, my phone stays on GSM often. 3G signal is good in the area, and when I check my friends' phones, I find out their phones are on 3G network but mine is on 2G.
When I choose WCDMA Only, phone registers on 3G network and works without any problem. But switching back to auto connect, cause the phone to register on 2G again after some time.
So is there any configuration that tells the phone to stay on 2G if 3G signal is weak?
Please help if you can.
Thanks in advance.

The cell tower does this by signal quality, and most of the time distance dictates quality. I myself have asked around for AUTO 3G/4G only, but it seems like a subject where nobody has done any research.
Does your 3G signal differ from WCDMA only compared to Auto mode? If so, try updating to a newer firmware, could be a modem/baseband issue that may has been fixed in the mean time.
Technically it should grab the highest network of the three. So LTE has priority over WCDMA, which has priority over GSM. So even if WCDMA has one bar, and GSM 4, it should grab WCDMA until it completely loses that signal.
Have you tested another SIMcard in your phone? It may very well be a SIM problem.

You say it is fault of the cell tower?
So why phones of my friends are ok about this issue and register on WCDMA?
I flashed 3 different lollipop ROMs but nothing changed. ?

Yes. That's exactly what I expect my phone to act about switching between network types.
I never tested another SIM in my phone. So I will check that as soon as possible. I will post the result. Thank you.

I have a new SM-G935FD purchased in the UAE. The software version is MMB29K.G935FXXU1APD1. The phone has a "United Arab Emirates" section in the About page.
I travel a lot. I generally use a local SIM when I am in a country for some time. Right now I am in France. I am using a SIM from Bouygues Telecom but I have no 4G/LTE service at all. The phone is connecting at H+ and also at 3G, but it is not showing 4G/LTE at all.
I will be in several other European countries as well as the US soon. I specifically purchased this phone because it has all the LTE bands for the countries I spend time in. This same SIM does give me LTE connections on Bouygues when I use it in my old phone (a Motorola X 2nd Gen). I had expected this phone to just work on LTE everywhere that I typically go.
I have looked through these forums and see a thread or two about others with LTE problems. But no clear solutions.
I have tried various apps such as LTE Discovery (no luck) as well as 4G LTE Switcher - using that if I set "LTE only", I get no service at all, and then have to reboot the phone before I get service back.
Is there something I need to do to get LTE?
Thanks.
Have you put the SIM in the correct slot?

Yes, the bottom slot. The SDcard is in the top slot. The SIM is showing in the phone as "SIM1".
Strange. I have a G935FD and it works with LTE no problems. I've used it in Singapore and Indonesia, with different SIMs and all work.
In Settings - Mobile Networks - Network Mode, it's set to LTE/3G/2G?

Yes it is. I've tried changing to one of the non-LTE modes and back, but no change.
In the About device / Status / SIM Card status page, I see Mobile network type as UTMS. Shouldn't that have LTE and, if so, how do I change it?
Mine says the same, but I'm only connected to 3G at the moment, so I don't know if it's normal it not. I have a 4G card in, but I'm out of my area's 4G network range.
Edit: Actually I was connected to my wifi. Now I'm connected to my 3G and it says HSPA+ now
Edit again: Ok, so my phone is jumping between 3G and H+, which is what's changing.

Ah, mine is doing the same. I see Mobile network type jumping between UMTS and HSPA+ if I watch for a while. Obviously that field is a status field, not a setting field.
Thing is, I am in an area with full LTE coverage.
At least you seem to be confirming that this should work. Still need to figure out what the problem is.
I have the same Problem in Spain. With a Vodafone Card I dont have 4G Connection (The same card in a the Galaxy S5 of my wife works with 4G). But with a Yoigo Card I have 4G Connection. The software version is MMB29K.G935FXXU1BPH6. The phone has a "United Arab Emirates" section in the About page too. Any Idea?
Thanks
