please excuse my ignorance, but what would be the purpose of this?
so that it dosent jump around from 3g 2g if its auto and your not using data it automatically defaults to 2g i think to save battery then switches to 3g oir hsdpa 3.5g or what att calls 4g on demand this keeps it locked on wcdma or 4g to my knowledge

seems like it reverts back to auto after a reboot
This makes the phone work on Verizon, right?

See that's what I thought too. ATT = GSM, Verizon/Sprint = CDMA.

Mine goes back to auto as soon as I back out of the menu. Am I doing something wrong by using the back button?
wouldn't this, by locking it, render the phone useless when traveling out of area that support that network?

Mine does the same thing. did you figure out how to do it? I have been trying but I couldn't do it
I found this here in the forum someone posted and it worked for me thanks for him.

Here's an alternate method I puzzled out (and then afterward discovered it was already posted in thread 751237. It's a bit faster and has the advantage of surviving flight mode; still gets reset upon restart.
Dial *#*#2263#*#* (mnemonic: *#*#BAND#*#*).
This brings up the Band selection menu which you can also access from the above method by dialing *#*#197328640#*#* then going into DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL.
Select [3] GSM BAND
Select [1] GSM ALL
Select "Select GSM All Bands"
Menu key > END
To switch back, go to *#*#2263#*#* and select [1] AUTOMATIC > Select GSM &WCDMA All Bands > Menu key > END.
Something else I'm trying out is switching the acquisition order so when it is in "dual" mode, it'll try GSM first. Even so, it will still switch to 3g if there's enough signal. Seems to help keep it on 2G though, when it would otherwise cling to a faint 3g signal with 0-1 bars.
To do that, go into the NETWORK CONTROL menu (see above) then
Select [4] AQUISITION ORDER (yes they misspelled it)
Select [2] GSM->UMTS
Select "Select ACQ_ORDER_GSM_FIRST" (at least they abbreviated it correctly)
Menu key > END
This option does not get reset upon phone restart.

I did this and now my sms or text messaging don't work help
I had this happen too, but I didn't use the above method. Don't know what happened, but when I checked message settings, I had no number under "Message Center" did a quick google search and found an ATT number "+13123149810"...now it works again.
Did u call the number
Never mind i fixed it.but now in my network type it says umts is that faster then hsdpa and are there any other number sequences i can use to tweak my phone
I'm getting RAT restricted, which I got on my Vibrant but never my Captivate...
How can I change to show the different bands?

wcdma and cdma have nothing to do with each other. wcdma is also known as umts, the base part of 3g (and 4g when hspa+). hspa is a protocol that runs on top of this cell technology providing higher data speeds. gprs (known as edge, and some times called gsm) is 2g. you can turn one or another off so the phone does not seek and connect to both services, which could save battery life. even though ive yet to see my phone find less than 3g/4g in houston, i still dont turn it off, just in case.

Thanks, John Madden.
Hello,
I recently bought a At&t HTX one X. It has a Unlocked Bootloader and i have also unlocked it so that i can use it with other Service Providers. But i found out that the 4g is always on and when i go into the network setting, the option Data Roaming is disabled.
I am loosing a lot of money because of this.
Under the mobile Network Settings i can only see 3 options .
1. Data Roaming [This option is disabled]
2. Access Point Names
3.Network operators
Can somebody please help me with finding a solution to get 4g disabled?
Thanks in advance
Go to dialer and dial *#*#4636#*#*. Go to phone information, and pick wcdma preferred.
Sent from my One XL
ok cool.. now i see 4 options
1. Phone information
2. Battery information
3. Usage statistics
4. Wifi information
I went to phone information : - set the preferred network type as GSM only
Now i can see the 4g symbol disabled... great
But now i see the "E" symbol on.
How do i get rid of that ?
"GSM only" is this the right option i selected ?
more info
WCDMA preferred option is keeping the 4g active. i am a GSM user so tried GSM only and it worked. but the E symbol is still on.
4g = hspa (3.5g) 4g LTE = LTE
So wcdma preferred = cell and 3g
GSM/wcdma/lte = cell, 3g, LTE

This doesn't work on the AT&T version (and stock ROM), it will just go back to the default setting.
Only way to really shut it off is to flash a ROM with the LTE toggle.
thanks redpoint. can u suggest me a link where i can get step by step instructions to the rom you are referring to.
this has to get asked atleast 5 times a week since the phone came out
I buy Unlock Phone Samsung Galaxy s II i727r LTE Rogers from Canada right now iam in India my android version is 4.1.2
When i open Network Mode Its showing me
GSM/HSPA/LTE (Auto connect)
GSM/HSPA (auto connect)

HSPA Only
1) When i select any of the above option except "GSM only" its showing me weak network signal only 2 to 3 point instead of 5 and its keep on changing frequently not stable and its shows 4G sign but internet speed is good but weak signal because 4g Won't support in india
2) when i select "GSM only" then its show full signal and its work fine but its show 'e' sign means 2g speed very slow internet speed
3) So i talk with Idea Operator they told you select WCDMA Option but that option is not available so how to bring that option in network mode
so please help me to solve this signal problem with 3g running right now weak signal with 4g
Thanks in advance
Hi
Your observation is true..I have Skyrocket,but the ATT Version,using with BSNL..
My network mode is not exactly the same...so..I have 'WCDMA Preferred'..and using it I get 4G(HSPA)..but with 1 or 2 signal bar at my home...but at some places I get good signal(4G is not avaialbale everywhere).Since I'm not a internet freak,i switched over to 'GSM Only'.in which I get at least 4bars..with good internet connectivity('Edge'!)
India is not truly a 3G place,leave alone 4G..Mind you this is the situation at 'India's so called silion valley'--Bangalore:highfive:
If the Rogers one don't have this,may be FLASH a ATT ROM---I use

Have had the phone for a week with no success even with rogers support
Gave me the LTE APN and my phone isn't connecting to LTE network, I added it manually still with no success
Sim card connects to LTE in my old xperia with no issues
Network keeps jumping from 3G and 4G
Don't have any clue on my next step and rogers blaming the hardware as they don't have any other resolution
is 4g the same as LTE and maybe I just don't know..is there anything I can do to test the lte antenna? I would like to rule out the hardware but I don't think its the hardware......
any help would be greatly appreciated
Hi
Thanks for writing to us at XDA Assist. Open your dialer and enter this code:
Code:
*#*#4636#*#*
That will open a menu from which you can select Phone Information, once in the Phone Information screen, scroll down and you'll see a drop-down menu where you can select network types, try selecting "LTE only" to see if you can connect to an LTE network.
Also, what phone are we talking about here?
No response in two days, thread closed.
I am using cynogenmod 13 latest build all things working perfectly but I'm unable to change connection type to 3G or LTE if selected 2G I have to go to flight mode and then I can change the connection type to LTE only still can't change it to 3G. When it's selected LTE as default even that time also the data connection work still as 2G sign showing as E even if I select LTE never get the H/H sign on my service provider Vodafone India please help me... and sorry for my bad english.
I had a similar problem with CM 12.1, but I solved it changing the APN. My phone has 2 APN available, I just selected the one it wasn't using and I got 4G and 3G again after some minutes.
Hope it helps.

Try changing the APN as Secuential said. For Vodafone India, I think it says 'www'.
If that doesn't work, try manually changing it.
Enter *#*#4636#*#* in your dialer.
In the 'Testing' window that appears, go to Phone Information.
Scroll down to Set preferred network type: (The default is LTE/GSM auto (PRL))
Change it to WCDMA only.
It should show H sign after a while.
Good luck.
(Though, keeping WCDMA only can increase battery usage. Change it to 'WCDMA preferred' later)
