Hello,
I have been trying hard to find a way to disable 2G on my MIUI Rom. The problem is that the "WCDMA Only" option is not available in the JB MIUI rom and I do not want to let my phone to to 2g as its roaming (in Canada, the AWS providers don't have 2G overlay)
I Have tried the *#*#4636*#*# method but it reset s to "WCDMA preferred" after a reboot.
I have also tried to modify the build.prop but it did not take effect. (Set ro.telephony.default_network=2)
Anyone have any ideas to stop the phone from going to 2G for good?

That is the correct line for setting WCDMA only. If that didn't work, then....?
i9505 LTE/WCDMA Only (autoconnect), possible?
I'm not sure if someone already did this but, is it possible to totally disable GSM and let LTE/WCDMA auto-connect?
I'm using i9505 and GSM is included in the LTE auto connect option on the network types.
Hope there is LTE/WCDMA Only (autoconnect) option.
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

App doesn't seem to work, when I hit "Select Radio Band" it comes up with "Set GSM/UMTS Band" and nothing else.

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.
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]

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.
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
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.
