Switching from auto to GSM mode selection. - XPERIA X1 General

I live in the United Kingdom and often would like to use my Xperia in GSM mode to conserve battery life. But which is the correct mode to choose?
When i go into the phones settings/band it offers me
GSM(900+1800)+UMTS(2100+900) but also offers me
GSM(1900+850+UMTS(1900+850)
Which is the correct one for me in the Uk ?

i think that you would use the first one you listed since umts850 is an american 3g band used by at&t

If you just want 2g, set "Select your network type" to "GSM".
There is no need to change "Select your GSM/UMTS band" from "Auto", but if you insist it's "GSM(900+1800)+UMTS(2100+900)"

thanks for that info...much appreciated.

T-Mobile USA - Preffered network type?

this is for the T-Mobile USA people.
Please help me understand what my settings should be? i was WCDMA Preferred and dont know exactly what GSM auto (prl) and all those other once do. I live in Texas and plan to travel so i want to make sure i get the best network while on the road. In my home i get HSPDA and 3G icons. Does anyone have a list of what everything is and does for what carrier?
what is the difference between GSM auto (prl) and GSM/CDMA auto (prl)?
i would like to add a note that i am worried about when traveling and leaving t-mobile 3g what will happen? will i just lose network if switching to gsm auto prl? this is why i am asking of incase i am totally out of t-mobile, will running gsm/wcdma auto prl allow me to use other networks?
i honestly would not mind if i had to switch between options when on the road and when in the city if i must.

Concerning the *#*#4636#*#* menu

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.

[Q] How do I get 3G network mode option on a GT-P1000/P1000XXJID?

Hello,
I recently received a Samsung Galaxy Tab (GT-P1000 Int'l Edition w/ white backplate) as a gift.
I live on Guam. The Tab was purchased from DoCoMo Pacific (NTT DoCoMo's Pacific sales/service provider), but I use a different local carrier as I prefer their 3G service.
The phone only offers GSM and WCDMA option in Mobile network settings->Network mode.
Is it possible to flash to a different ROM that would enable the 3G option?
I'm new to Android, as I'm a iPhone/iPad convert.
Any help would be greatly appreciated.
Thanks in advance.

WCDMA *is* 3G.
You need to check you APN to see if it is set up for your carrier.

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.

[Q] LTE Bands supported by UK LG G2 (D802)

Does UK LG G2 (D802) support LTE Band 20 (800 MHz) used by O2 UK?
Does anyone know this?
Use info command

1) Go to Phone, just enter following command,
*#*#4636#*#* (no need to press Green Dial Button after this).
2) Once you enter last *, Testing menu will appear. From that menu,select "Phone Information"
3) Scoll down little and you will see "Set Preferred network type". There is dropdown at this location which shows all the networks.
Just note,This is testing menu. It will show all the options like CDMA/WCDMA, GSM, LTE etc. It does not mean that all the networks are supported.
Just insert LTE sim and change option of preferred network from above list to LTE only and check if that works.
Officially it supports 850, 900 bands. But I am wondering if the bands are only controlled software side seeing that the antennas and hardware seem to be streamlined across all versions.
On the box it says:
LG-D802
LTE 2100/1800/2600/900/800
6GB
BLACK BLACK
Thank you for the test menu you solved my problem I just bought the d802 would not work on my 4g sim in uk changed to lte and all good thanks.
Sorry to bring this one back form the dead but the original question doesn't appear to be answered to me...?
I am on Three in the UK and they are rolling out 4G on 800Mhz and 1800Mhz. Complete noob here, but from what I have read 800Mhz has greater range and building penetration (at the expense of some speed), which is great. Except that the G2 doesn't actually support 800Mhz LTE, or does it?

same here with tesco, set the above and worked fine, but after restart just defaults back to gsm/wcdma auto as preferred and need to go through the steps again to achieve 4g. Anyway to save this as preferred?

I found and downloaded the free app 4G LTE Switch from the play store to help with this.
While it doesn't solve the problem of having to manually select LTE after each reboot, it saves you from having to dial the code yourself. Instead, just launch the app and it takes you right to those settings. I find it very useful and time saving! :good:

cheers for the heads up, i'll give it a bash, still find it very strange that a 4G phone doesn't come with an easier way to actually activate 4G.

No problem man. I didn't give up searching and actually followed this thread, where it says "No 4G/LTE?" and tried putting my networks actualy LTE band (17) in there instead of 11 and 13. While it now gived the option of selectiong LTE in the dropdown menu of preferred networks, for some stupid reason, the phone STILL doesn't save the setting and you still have to go back to the menu again after a restart to enable LTE.
While it is even easier than the method I said earlier, still frustrating that even after selecting it in the menu, that it still defaults back to GCM/CDMA!
There just HAS to be a way to make this stick. Any devs out there who could look into this further???

Hello,
I am from Portugal, so your mobile could say something rather different. But in essence is all the same.
My version is the D802, International model, just like yours.
1.st step - Provider:
The provider part is always the first to be deal with.
Make sure you go to your operator and ask to enable your SIM-card to have access to LTE.
2.nd step - Equipment:
Go to Definitions -> "Network" tab -> "Sharing connecting & Network" on the bottom -> "Mobile Network" third from last ->
a) Make sure that "Enable Data" is checked;
b) Go to "Network Mode" and choose the option: "GSM (2G) / WCDMA (3G) / LTE (4G) auto".
This way you will always have automatic access to the best network available.
All the people who choose the 4G/LTE only option should check this mode, so you can access 3G when 4G is not available, instead of having no connecting.
Any doubt you have, just ask!
Best regards.

Step 2 in bold, that's not an option. 3 options are
1. GSM / WCDMA auto
2. WCDMA only
3. GSM only
However when using the 4G switcher app you can change it to GSM (2G) / WCDMA (3G) / LTE (4G) auto and it works fine, but on reboot just defaults back to GSM / WCDMA auto.
Our D802 supports 1800 Mhz and 2600 Mhz frequencies for sure.
But to get the LTE toggle to show up in the network selection menu, we need to insert a LTE capable sim or usim. Tried and tested and not a here say.
If you do not get LTE option in network selection then your sim is not LTE capable. Simple.

The option in my phone is:
"GSM (2G) / WCDMA (3G) / LTE (4G) auto"
All this information at one option.
So the phone can choose the highest band level.
This is a problem with your ROM or a problem with your SIM.
And, as I said in my first post, go always first to your provider and ask him form help.
Making sure the SIM part is enabled and fully accessible.
The bands are not important here.
That is because, if you bought your smartphone in the UK, LG made available the D802 model to make your smartphone antenna frequencies correspond to those available at your country.
This will matter if you want to achieve maximum speed of 150Mbps.
But if you want just the regular user experience, you sure have access to LTE network.
In wikipedia (I could not find a good source, as GSMArena make no reference on the version D802)
Wikipedia -> LG G2 -> Specifications
D802 supports 4G/LTE bands:
800, 900, 1800, 2100, 2600
And here you can see the bands of your provider/network:
Wikipedia -> List of LTE networks -> Europe
EE: 1800, 2600
Hutchison 3: 800, 1800
O2: 800
UK Broadband: 3500, 3600
Vodafone: 800

Its a UK sim free handset, and i'm on tesco (which is O2).
Sim card is fine as tested in another 4G phone and defaults to 4G as it should after collecting the APN settings from the network. Checked the APN and both the exact same compared to the one the LG G2 is using.
I'm using stock rom and this happened initially on JB, then updated to KK, factory reset, and still the same, then updated last week, still the same.
From reading this thread looks like i'm not the only one.

Wikipedia, and other websites, say O2 only acquired 800MHz band for LTE.
And LG G2 D802 only supports:
850 (band 5), 900 (band 8), 1800 (band 3), 2100 (band 1), 2600 (band 7) MHz.
I saw this at PhoneArena, GSMArena and ATGSM.
This brings a problem for people which their carrier only emits LTE at 800MHz, when not supported by come smartphones.
But I recommend you all to ask LG about the frequencies supported by the LG G2 D802 version, and ask your network carrer/ provider for LTE frequencies.
That way you will be absolutely sure about its compatibility or not.

wikipedia is saying....LTE band support 800/900/1800/2100/2600, however tesco (o2) are definitely on 800mhz, so must be something to do with LG so it will no doubt be them who has to answer the question, and never do anything about it.
