No 4g with SM-G935K in EU - Samsung Galaxy S7 Edge Questions and Answers

Hey Guys,
I have just bought a olleh branded S7 edge(SM-G935K/Korean version) from eBay. I'm very happy with it so far, but it seems that 4g is not working, only 3g. I looked trough the internet, but couldn't find anything. What I do found out is that it supports all the correct 4g frequencies. It also looks that some of the settings are blocked or simply not there. For example, when I go into Setting - Mobile networks, I only see a greyed out Data roaming, normal Access Point Names and greyed out Status bar indicator. There is no Network mode and no Network operators. Maybe this is because of the olleh branding?
Thanks!

Hi,
I have got the same issue. but I have 4G working. I would like to know how to get data roaming working too. Any expert can point it out how to fix the data roaming would be greatly appreciated.
P.S. I am on Australia Vodafone network. I do get LTE and LTE+. I can share my setting if you need any info.

Telcel + HTC Aria = No 3G?

Hi guys,
I just bought this phone, unlocked it and inserted my sim everything was fine until... I noticed the "edge" icon.
It wont connect to the Telcel 3G network, I know that this phone is for AT&T network but Telcel uses the same frequencies (UMTS 850/1900), I tried "forcing" it to WCDMA only but it wont find any Telcel network.
What can I do? Does anyone have experience with this kind of problems?

Aria comes with APNS setup for AT&T data only. It's a simple fix - you can manually enter the info under wireless settings to add access point data for your carrier or you can just root and flash CM6, with has a huge - enormous default APNS database.
Here's a link to how the same issue was solved on the Nexus One.

Thank you! I'll try this right now!
-------EDIT-----------
Ok I entered the APN info, restarted the phone and Edge Icon is still there, with the "settings" on *#*#4636#*#* I changed to "WCDMA only" and the phone cant find a telcel network, only movistar, What is the problem? Maybe there isnt a Telcel 3g network near my phone? I used to have an iPhone 3G and I never had a problem with 3G Any thoughts?

This works perfectly.
My wife's Aria went into some factory reset and lost 3g, now it's back thanks to this.

[Q] Question about 3G network (WCDMA)

Hi all,
I'm struggling to get data connection over the 3G network, even though I've got a data plan and the settings seem to be on point.
I'm based in Dubai and I've got a Middle East tab (garbage as the firmware excludes the Android Market), so I've flashed a recent Euro firmware (JIP was the build if I recall)
When I go into network settings to choose 2G/3G/Auto, it shows me GSM and WCDMA as the choices. I'm pretty sure before the flash, it showed GSM and WCDMA. Is WCDMA the same as HSDPA?
The problem could be with the carrier, but I'm troubleshooting at the moment and this WCDMA is a bit confusing.
Any insights would be greatly appreciated. Thanks.
Have you checked your APN settings? Chances are that the Euro firmware doesn't have the APNs "pre-installed" for your carrier(s). The good news is that you can add them in manually if this is the case.
Regards,
Dave

If your display shows a 3G or H type signal, then your problem is a bad APN setting.
WCDMA is 3G and H on your display, if you have that then you're in good shape.
Search the net or the carriers website for the the correct setting, then create a new APN and data will instantly start to flow.
It was missing the apn setting. Justed typed it in manually and Im hooked up. Although i was bamboozled for a little while as the H didnt apear until i had turned off the wifi.
Thanks for all ur help guys.

[Q] Roaming Problem

Hello everyone.
I've been using this Omnia 7 for awhile. But today I noticed that there was a triangle in the top bar. Based on my experience with Windows Mobile, I guessed that would be a roaming indication. When I looked up online, my guess was correct. However I am still confused, recently I haven't changed my carrier, location, cellar setting etc . The triangle just starts to show. It was never there before today. I am worrying it will bring extra cost on my bill. Could someone help me fix this problem.
Thank you very much
p.s
Carrier: Canada Fido
Omnia 7: unlocked, no brand logo at startup screen, no brand logo at the back
Cellar Setting: Don't Roaming, Data Connection is off, Network Selection is automatic(no difference if I change to other options), no apn
It could be that your provider is using another provider's network if the original one doesn't have reception.
It's like this with my provider "Three" in Austria. The 3G-Network is running on their own network and in areas, where they have no reception with 3G, then my phone uses the GSM network from a different provider and shows the roaming-icon. It shall be like that so it doesn't cost anything more.
Ask your provider if roaming is planned there.

[Q] Defy, AT&T EDGE only

I have an unlocked Defy from T-Mobile USA that I'm using with my AT&T service, but I'm only getting EDGE wherever I go, no UMTS at all, and I've even heard of people getting it to run on HSPA bands. I know already that HSPA is available everywhere from my home to my workplace, thanks to my Atrix 4G. I've rooted the Defy and it's running Cyanogenmod 7 latest. Any help would be greatly appreciated, as I can find nothing on this forum or on Google to remedy the issue.
You should try to change the freq via baseband switcher.And restart.
Maybe you got the "2g only" checked in networks settings..uncheck that.
Settings >Wireless & networks > Mobile networks
You can also put automatic(2G and 3G) mode in GSM/UMTS network preferences.
Thanks for the reply Viper. I just noticed the baseband is set to some central Europe nonsense. Should I change it to one of the T-Mobile USA band settings? There's nothing there for AT&T.
Edit: I changed the baseband to US T-Mobile 3.Something, whichever was latest. 2G only was not checked. I'm still getting 2G only. Could it be my APN settings? Could I copy the APNs from my Atrix?
I'm having a problem with my AT&T connection as well, but I've been using my phone unlocked on the network since March with no problem. I'm new to modding, but OCD about streamlining my electronics. My friend suggested rooting my device and flashing a new ROM. I decided on stock Nordic Froyo, and it makes me so happy not to see all the T-mobile crap in my apps tray.
BUT the collateral damage is not so hot. I have no 3g or even 2g connection anymore. I tried the fix in this thread http://forum.xda-developers.com/showthread.php?t=944258 and was able to get a signal with 4 bars instead of the previous state of emergency calls only, but no letters like E or 3g and no ability to use the internet/transfer data. I also installed the broadband switcher in this thread http://forum.xda-developers.com/showthread.php?t=1052745 and tried all of the T-mobile US bands. No luck. I did rest the APN to default. No change. I've been using wifi, but will have to go back to work soon. Not having access to the smart part of my smartphone will feel sort of like having an arm cut off.
I'm not sure what to do next. I could try flashing another ROM, but from what I've read in the forums, that's no guarantee.
If anyone has any suggestions to help a noob, I'd be forever grateful.
Thanks in advance!
Thanks for the link, halah. Do I apply this as an update.zip from recovery? Or install?
Never mind, it won't work for me, for whatever reason.

No 4G/LTE with SM-G935FD

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
