[Q] Unsolvable problem with SAMSUNG GALAXY S5's 3G. - Galaxy S 5 Q&A, Help & Troubleshooting

Hi,
I am from Bulgaria and I bought a ATT locked SAMSUNG GALAXY S5(SAMSUNG-SM-G900A) from a friend.
At first wasn't able to use my Bulgarian sim card(operator : M-Tel) but then I paid for unlocking code and 5 days later I unlocked my phone.
I put the card into the slot and started the phone. The signal bar was showing full but I was unable to make calls or send messages because of "Not registered on network" message. After an hour of reading the internet I found this code *#*#4636#*#* and then went to "Device Information" and on "Network type I change" it to "GSM only". ( I used the code because in the menu I dont have "Network type" option).
However now I can only connect to GSM network which is the problem because my mobile data is only EDGE NOT 3G. Here I need your help of solving this.
The available option of "Network Mode" are as fallows:
WCDMA prefered
GSM only
WCDMA only
GSM auto(PRL)
CDMA auto(PRL)
CDMA only
EvDo only
GSM/CDMA auto(PRL)
LTE/CDMA auto(PRL)
LTE/GSM auto(PRL)
LTE/GSM/CDMA auto (PRL)
LTE only
Unknown
There isn't LTE network in Bulgaria so I am asking how to use 3G on the phone. Should I root it(not pretty sure how to do it) or something else?
I posted my question in Bulgarian android forum and one guy told me to switch to WCDMA prefered but when I do and try to connect the operator M-tel it says Unable to connect.
So thats my problem with the Samsung phone so I would be very happy if someone knows how to fix this and help me.
Cheers!

Just call your service provider and ask them to activate 3G......I had the same problem, they solved it.

I called the operator today and they told me that other user also complain about their newest models of Samsung brought from USA and it's a software problem and to check for a software update. This didn't sound like a good news. Any ideas? Or i should just wait for something to happen.

Disable GSM, use LTE/WCDMA only

I tried searching however could not find anything. Perhaps I may be using the wrong wording.
What I am trying to accomplish is to disable the GSM mode. What I find is the phone likes to jump to the GSM network and with that the internet connection just doesn't move at all. If I force the phone to WCDMA mode it work just fine standing in the same spot, so the phone is still picking GSM over WCDMA even when there is a good signal for WCDMA.
Current modes:
LTE/WCDMA/GSM (auto connect)
WCDMA/GSM (auto connect)
WCDMA Only
GMS only
Is it possible to have a LTE/WCDMA option?

I miss this option. The Xperia Z had this mode, I loved it. It was reachable via the common code *#*#4636#*#*. But this code doesn't work on the GT-I9505 with stock Samsung ROMs. But even with custom ROM, and working code. This special mode is missing. There are 2 switches for "LTE only" and "WCDMA only" but not both

You have to use "prefered network type" as seen here

This should work
Here is my screenshot. It only has "LTE/CDMA", which only allows me to use LTE. There is no "LTE/WCDMA" option.
Perhaps, this might be an idea for rom creators?
also interested in this.
yes, please add this function LTE/WCDMA only into ROM CYANOGENMOD.
because LTE/GSM auto (PRL) connect to 2G/3G/4G, and i'm not interested for 2G.
Did anyone ever find a solution to this?

Solution please ! I have the same problem also
True. I am able to use the following:
LTE/GSM (prl)
WCDMA (prl)
GSM Only (prl)
I am unable to use LTE/WCDMA/GSM
I am using XXUGNG8 modem, and I am unable to use 2G (network won't connect).
3G works in most cases, but it is still dropping. Only technology which works correctly is LTE...stable and fast.
I am unable to switch the network band to any other one. I tried it with service menu tool, but it does not work either (allows me to change to defined items above, and reverts back to LTE/GSM if I'll select anything else).
Is there a way to add support for more network modes? I am confident that my issues are not related to HW, as both bootloader, GSM modem and LTE modem are all of the same version - XXUGNG8, and I do have very good reception for whole band. I am just unable to switch over to 2G, and 3G is still dropping.
I live in Prague, Czech Republic, and I own GT-9505i variant
Any solutions guys?
any solution to this date? im interested in the same thing.
I finally found a solution that works on my Samsung Galaxy S5. Enter code *#2263# into your dialer. An option menu will open with "LTE/WCDMA Mode" only as an option. Works like a charm!
Wrong posted.
Hi,
Sorry to bump this but I have the same issue. I have a Galaxy S4 and it is very weird with its network selection.
The default setting is LTE/GSM auto, which I believe is LTE combined with the GSM Auto mode that everyone knows about - this being, prefer 2G instead of 3G in weak signal areas.
I have the following options:
LTE Only
LTE/GSM Auto
GSM Auto
WCDMA Only
GSM Only
WCDMA Preferred
Plus a load of other stuff about CDMA and EvDo (I'm sure that the GT-I9505 doesn't support CDMA or EvDo?).
The problem I am having is as follows:
Immediately when I got the S4, I realized that it was preferring GSM over WCDMA/HSPA. This was confirmed when compared with a Samsung Galaxy Ace Plus, on the same network, in the same location, and the Ace Plus (S7500) was choosing 3G, whilst the S4 chose 2G. Doing a bit of Googling led me to find the WCDMA setting, and after choosing that, the S4 chose 3G.
So all was good for the last 2 years, using WCDMA Only mode on my S4, as my mobile operator (Virgin Mobile) didn't have 4G access. Losing LTE wasn't a problem.
However, now I have switched to the EE network, I now face a problem. As mentioned above, there is the WCDMA Only mode, and the LTE Only mode - meaning that I am unable to have both 3G (WCDMA) and 4G (LTE) without also having GSM, and there is no way that I want to ever use GSM again, especially since that EDGE/GPRS are barely usable as data connections, GSM has sub-standard voice quality, and the S4 is choosing GSM over WCDMA.
A couple of examples, once on my way home, the S4 dropped from 4G to 2G and completely ignored 3G - despite being right next to a 3G mast operated by EE (albeit on the old Orange code). On WCDMA mode, the phone always connects to the Orange 3G mast. Thankfully, a bit later on, it did pick up 4G again, but if I was streaming Tunein Radio, that would have been a disaster (it would have dropped the stream).
A bit later on, on the same journey, the phone also went to 2G, from 4G - despite being in a reasonable signal area for 3G. Why didn't the phone choose 3G? I'd had enough by then and switched to WCDMA Only mode; result? 28% 3G signal (3 bars)!
It's also happened on my local mast, until a few weeks ago. The S4 was choosing 4G from a more distant mast (strength 50%), instead of 3G from the local mast (strength 60%). When I went downstairs, to the kitchen, the signal strength dropped and the phone went straight to GPRS! GPRS is likely to give about 30kbps max, so I don't know why the phone was doing this - although about 20-30 seconds later, it did then go to the 3G from the local mast.
I can't use LTE Only mode as (a) the 4G rollout isn't complete, and (b) the S4 does not support Voice Over LTE (VOLTE), meaning that in 4G only mode, I have no way of accepting or receiving calls.
I need a 3G/4G mode (LTE/WCDMA) on my S4, that doesn't use 2G at all, because 3G/4G signals are present virtually everywhere on the EE network, and it would stop the S4's crazy behavior.
Any suggestions to remedy this would be appreciated. I am not rooted, though if someone knew how to root the phone for me, it could be a possibility, as it is out of warranty.

Are you sure you have bought Samsung Note4?

Does your mobile operator has LTE? Usually you don't see LTE option when your network doesn't support LTE.

Try this way (ROOT is required):
- Install ES File Explorer, open the menu and enable Root Explorer option.
- Locate the file /data/property/persist.radio.lteon
- Open that file, and change its content from false to true
- Reboot the phone.
Hey Jusho,
I'm having the exact same issue with your issue, no LTE option with TELKOMSEL. Have you fixed your issue? If so, how?
Did you purchase 910G in Singapore?
I went to Singapore recently and was able to go to Samsung Service Center... we tried a couple of things :
- Use M1 USIM card in MY Note 4==> LTE option appears
- Put my TELKOMSEL USIM in THEIR Note 4 ==> LTE option disappear from THEIR phone
- Put OPTUS (Australia) USIM in MY NOTE 4 ==> LTE option appears
Today, I went to Grapari and asked them to replace the USIM and tried with the local Samsung Store :
- Put TELKOMSEL USIM in their Samsung EDGE ==> LTE appears
Any idea?
Hey guys, I had that same problem on my galaxy S4 before. I used a Straightalk sim card running on Tmobile. I called straighttalk and they replaced the sim card and everything worked.
Call your providers and ask them to change your sim for LTE compatibility. That is if your providers support it, and your phone supports the LTE bands.
Good luck

I did mention that I have replaced with the new USIM (4G card) and LTE option won't appear. And yes, my provider supports LTE Band B8/900 Mhz

[Q] 4 G LTE and 3G not working on Yureka

hi,
i bought a yureka, everything is great. its just that i'm unable to use 3G or LTE on my device.
it always shows edge. on my device. and runs 2G
in mobile networks preferred network type is LTE. and i have LTE service in my area.
on phone info *#*#4636#*#* By default the preferred network comes as LTE/GSM auto(PRL) and network type shows EDGE.
i have tried changing the preferred network to WCDMA preferred, then radio on/off, still network type shows as EDGE.
i have unlocked the boot loader and then flashed the modem (NONHLOS.bin) from Rohan A joshi thread in XDA yu yureka.
still im unable to use 3G or LTE.
the SIM is perfectly fine, if i put the SIM in some other phone like iphone, everything works fine.
can someone please help me i will be thankful.
Try WCDMA Only
---------- Post added at 01:38 PM ---------- Previous post was at 01:38 PM ----------
Or disabling one sim which isn't meant for internet
I am also having the same problem only edge,and phone info shows as "gsm only " no matter what I do its not changing to wcdma or any other options help

no idea, im also still waiting for any reply
Partial solution found.... On LTE sim slot i. e. Sim no. 1 using *#4636#*#* and then select wcdma will change the network to 3g.
But 2nd sim the wcdma option not activate.
Same problem for me too
I'm also facing the same problem. Selecting WCDMA only option is not working. It always comes back to GSM only mode. End result no 3G and hence no internet. Only whatsapp is working. Should I ask for replacement. 10 days is not over for me yet..
Finally 3G actually work on YUREKA
Finally after lots of hit and trials I got solution.
Two things you need to do.
First
a.select default type as WCDMA only
b. enter *#*#4636#*#* from keypad.
c. Go to Phone Information and turn off radio.
d. Now select WCDMA only and click on turn on radio
Second
Delete ur APN settings and set the setting manually as per
your service provider. search setting on google.
Finally MY YUREKA WORKING ACTUALLY ON 3G NETWORK
Note : Preferably do all settings on SIM 1 inserted in LTE slot
WCDMA only
I did that. Fortunately this time I'm able to select WCDMA only. Device started working in 3G. Now when I go home, again 3G is gone.
Did that selecting WCDMA only again. 3G is back.
Every time I need to do this like selecting data connectivity/Wifi. I'm getting sick of this. Unfortunately 10 days period is also over
Finally 3G working..
Hey Guys,
If anyone here still facing problem with the 3G connection.
Deactivate your Mobile Data Connection.
Try going to APN setting remove the Proxy Value and Port Value then Save it.
Finally, activate your Connection.
Its working for me.
This is not a bug
check on forum
that problem of APN
how to set a default network?

hello,
i dialed in *#*#4636#*#* and got that menu the first time i turned off radio and selected wcdma only and turned on radio then rebooted.
i dont know why but it says no network available.
so i changed it back to lte/gsm after switching off radio and then switched it back on. i got the network back still on 2g.
but now everytime i reboot it goes back to wcdma only and no network available..
how do i make lte/gsm the default network so that i dont have to keep switching networks when my phone boots up

I have had this problem too in a while. But I guess it go resolved somehow.
First there is SIM 1 which is only good enough to run 3G or LTE networks.
I tried a lot to run it.
Sometimes switching on and off the airplane mode gave me the 3G connection.
Not sure about LTE, the national capital still doesn't support LTE.:good:
Give it a try!
Guys first of all you need to know that only SIM 1 supports 4G LTE.
and both sim slots supports 3G but you need to get activate 3G Services on your number.
i am using 3G of Aircel and its working fine for me(Sim2).

I just changed to WCDMA only and 3g started working.
My issue was 3G will work for a day then changes to 2G. Then I have to remove the sim and change slot for 3G to work. Will wait and see how long this will remain 3G.
Good 2 know

Hey Anurag, Can you please post the APN details of Aircel that you have on the Yureka? I have tried that *#*#46 etc and changing SIM from SIM1 slot to SIM2 slot. No difference. Still on EDGE.
Thanks,
Kiran.
Setting as mine:
Name: Aircel
APN: aircelgprs
MCC: 405
MNC: 810
APN type: default,supl
APN protocol: IPv4
APN roaming protocol: IPv4
if still not working go to your nearest aircel service station..

Thanks Anurag. There was some issue that even though it was same setting that I had, I still could not get 3G. Anyway, I upgraded to Lollipop and the problem has been resolved. Now I can get it to work on 3G Speed itself. Same APN "aircelgprs".

Unlocked Sprint G6 on TMUS

Got through the Sprint process and had the G6 unlocked for TMUS. Got the APN set up. Issue is the phone is generally in 3G. I can see under the mobile networks settings, I have the following options:
Automatic (current setting)
CDMA/LTE (LTE yes, calling no)
CDMA
GSM/UMTS
Any idea if there is a way to get a GSM/LTE option. Newbie here, but the phone seems to have the right bands, just the CDMA centric Network settings.
Ideas?

Have you tried through the hidden menu
Can not get into the esecret menu. Get bad MMI
I tried to get into the secret menu to change the network setting, but when I try, I get a bad MMI message. I am using
<star>#546368#<star>993#
Was a Sprint model. (993)
Any ideas. I saw the secret menu on YouTube and it does seem to have the gsm/umts /lte setting I would need.
