AT&T HTC ONE X - 4g setting disabled

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

[Q] 4g disappeard

yesterday i flashed 23.0.A.2.93, to root and get recovery. when the flash was finished and it reboot, my 4g was gone, and i only got edge. i live in the woods, but i had 4g before. when i went to town, the E changed to H, but still slow, and no 4g. now i've flashed back to 23.1.A.1.28 (modded CE1) and still no 4g. why is this, and what can i do to fix this? i have the right APN

Did you check to make sure 4G is enabled? You can press the 4G switch from the quick settings menu or go into the settings app and then under Wireless and Networks ...More >Mobile Networks > Preferred Network type. Perhaps you have WCDMA (preferred/GSM selected, in which case you won't see the 4G icon come up even if you're in a 4G area. Switch to 4G (preferred/WCDMA/GSM and after a few minutes, your phone should switch to 4G. If it doesn't then tap on Network Operators and see if your network has a 4G signal in your area. You'll see an entry for each available 2G, 3G and 4G signal.
You can also change the preferred network type from the service menu. Dial *#*#SERVICE#*#* and then tap on Network Mode.
Hope that helps.

it was on "WCDMA (preferred)/GSM", changed to "LTE (preferred)/WCDMA/GSM", now i have LTE, but thats not the same as 4g right? *#*#SERVICE#*#* > service settings the "Network Mode" option is grey and it says "N/A"

Suddenly, it started with 4g again, thanks

Help 3G, 4G/LTE Not Working on Cyanogenmod 13

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)

No 4G / LTE in Austria?

I'm customer of the local carrier "Drei" (Hutchison) but my Pixel (bought in Germany) does not connect to the 4G / LTE network.
The support of Drei is not able to help me. LTE is working fine with the same SIM on the OnePlus One.
Any clue how to fix that?

There is regional problem I came across. In India here we dont have VOLTE support on pixel

What LTE bands do they use on Drei?

Same happen to me in Portugal with MEO. I can't seem to solve it. Talked with my carrier support, they don't know why I don't have 4G/LTE.
I never got 4G, but my SIMCard has no issues with iPhone getting 4G right away.
Is it Pixel issue? I start to think it is..

3/Drei is listed here: https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe#Commercial_deployments
The specs of the Pixel are listed here: https://madeby.google.com/phone/specs/
That is all information I have got.
Is there any possibility to display information about nearby LTE senders via an app?

After activating "LTE only" via *#*#4636#*#* it works. Everytime I search for networks or reboot my phone it still connects via 3G and switches back to "LTE UMTS auto (PRL)".
Seems to be a software issue.

I use the phone on Verizon and don't have any problems connecting to LTE using any available mode (Global, LTE/CDMA or LTE/GSM/UMTS). However, if I set the mode to LTE-only via the menu, it will also reset when I either reboot the phone or if I just open the "Cellular networks" menu. I think it's how it supposed to work because that menu doesn't have the LTE-only option, so it resets the mode to whatever you see there. The solution is simple - if you reboot the phone change the mode again and don't go to the "Cellular networks" menu
Regarding why it doesn't work with "LTE UMTS auto (PRL)", it might be because Drei didn't configure a handover from UMTS to LTE on the cell site you're connected to. It looks like Pixel finds UMTS signal first, but doesn't know that LTE signal exists due to a missing handover. Another phone might be fine if it searches for LTE signal first. But if you can see another phone switching from UMTS to LTE in the same spot, my theory is wrong.
