I tried messing around with the options in the *#*#4636#*#* keypad menu to help improve battery life, I read that changing options under "phone info" in the "set preferred network type" can help that regard, but I wanna change it back to the default. Anyone know what it is? Here is what I can choose:
- WCDMA preferred
- GSM only
- WCDMA only
- GSM auto (PRL)
- CDMA auto (PRL)
- CDMA only
- EvDo only
- GSM/CDMA auto (PRL)
- Unknown
I think it's the one that's bolded but I could be wrong. If anyone that hasn't manipulated these settings could enter the command in their keypad and tell me what they have, or their opinions about these settings I'd really appreciate it.
Default is WCDMA preferred.
so does anyone know which options to use?
ie for different countries and different regions..
on my HD2 it is "WCDMA preferred"
gsm auto (PRL)
If you choose gsm auto (prl) it will still use all networks but have less data drops and use less battery.
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 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

Go to settings>more>mobile networks>network mode and select wcdma only If you don't have signal than probably that phone doesn't support certain frequency the one your carrier uses for 3g, that happens when you buy phone on foregin country or your carries simply uses some other than usual frequencies.
Hi,
In Settings, we only have 3 choices of networks.
In French :
- 2G/3G/4G (automatique)
- 2G/3G (Automatique)
- 2G Only
My "global settings" are :
preferred_network_mode0=11
preferred_network_mode1=20
preferred_network_mode =20,20
Maybe I have changed preferred_network_mode0 to 11 with an app ?!?
I've changed to :
preferred_network_mode0=11
preferred_network_mode1=11
preferred_network_mode =11,20
but changes are not taken dynamically and if I stop/start ril-daemon, values are restored to default.
Is there a way to turn preferred network type to 4G Only (or LTE Only) ?
Before someone asks, it is because, at work there are a lot of gsm antenas and my provider has a really poor bandwidth in 3G (in fact it is a limited roaming from another provider) whereas it is good in 4G. So I prefer a poor 4G connection instead of a good 3G one.
Regards.
