[Q] Unsolvable problem with SAMSUNG GALAXY S5's 3G.

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!

1. WCDMA only
2. Manually register to your Network by Settings [Settings>More Networks>Mobile Networks>Network operarors]
3. WCDMA prefered

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.

Still no LTE option

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] Unable to get 2G /3G on my lg g2 320s in India on idea network

Dear friends
I got this korean version of lg g2 320s. I am able to use only gprs on this. I have tried setting the apns manually but not able to get 2G or 3G to work.
When i go to network settings it shows only 2 options for Network Mode. first is LTE preferred and second is 3G only. My carrier Idea says i need to select wcdma which i don't see.
I went thru some forums before posting here and tried 5457#*320# i tried changing band selection but still my device wont get 2G or 3G signal.
Please help me or point to the right location.
Thanks

LTE does not show up as option with specific Operator (MVNO)

I have a SGS5 (SM-G900F) downgraded to Kitkat. (4.4.2)
I can use LTE with one operator A (4G shows in statusbar, speedtest measures above 50Mbits).
I bought a sim for operator B but I cannot switch to LTE mode in Mobile Data Settings -> Mobile Networks -> Network Mode. Any option with LTE is simply not available.
I tested the sim for operator B on an iPhone 6 plus, it works just fine.
I have found some guide for secret codes and walked through it to force LTE. It works, but it does not switch to 3G automatically when I receive a call (it does this with the card of operator A)
So I know that my phone does support both operators frequency bands, I can force it to work, but I want to have the convenience of automatic switching on a phone call.
Is there a list somewhere in the software that has flags for networks to enable and disable LTE options in the menu ? Can I edit this ? Where is it ?
Will updating my Android version fix this ? ( I would really prefer to avoid this, since I use SnoopSnitch )
Operator A is: Vodafone (DE), A1 (AT)
Operator B is: HoT (AT)->MVNO for T-Mobile (AT)

3g and 4g problem

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.

Plz guys.....I hope u can solve this problem....the sim is perfectly working in other phones!!!!

Hi,
What you need to do is as follows:
1) Put your LTE Sim in Sim 1 Slot
2) in Sim settings for Sim 1 select LTE preferred - for 4G
If you want to use 3G then select 3G
3) dial *#*#4636#*#*
4) select - WCDMA Only - for 3g
Select - LTE only - for Lte network ( when u select lte/ gsm auto it will revert back to edge if no proper LTE signal is available)
Now you are good to go. You don't need to change the sim settings if your reboot. But you need to change the settings in phone info everytime you reboot as it will reset to LTE / GSM Auto prl.

But Sir, the network mode goes into HSPA. Will I be able to connect to my 4G network?

If you do as stated above you will be definitely on 4G dear. I'm doing the same on CM 13 on yureka
