Is there a network mode to toggle 2G/4G on T-Mobile?

Wondering if there is a way in the network settings to force 2G ONLY or 4G?
WDCMA Preferred
GSM Only
Something like that?

Only way is dialing *#*#4636#*#*
And selecting it there.

This app is much faster than dialing:

I use it all the time to quickly change from HSPA to EDGE.
You're welcome.

Think you have to be rooted. Install the app Advanced Signal Status and under "additional info", then "device info" you can choose for different options.

when I am using my galaxy note 3, I input *#2263# to go to a menu where I can force LTE/WCMA my device and mostly it connects to only LTE.
in the Galaxy tab S , the code works but the option for LTE only is missing. so now I continuously connect to a slow 3g network.. bummer...
*UPDATE:
apparently you have to deselect all GSM bands and just select all LTE and WCMA bands.. you wont be able to use GSM bands but your device will lock on to LTE connections if avaialbe, 3g will apply if LTE is unavailable. hope this helps

Note 2 no GSM??

Do you have the secret dialer on this phone? Dial *#*#4636#*#* (*#*#INFO#*#*). Select "Phone settings" and scroll down to "Set preferred network type:" and make sure you've selected LTE/GSM/WCDMA/CDMA auto (PRL)".

I could not get that (*#*#4636#*#*) to do anything.

Use this phone on Cricket Wireless?

I'm currently using the AT&T H810 on Cricket Wireless and am wondering how to get the data to work with this Verizon variant. I can make calls when I put my Cricket SIM card in, but I get no data. Any ideas or anyone already get this working? Thanks!

Did you change the APN settings? Also, AT&T uses LTE bands: 2, 4, 5, and 17 primarily. The Verizon G4 doesn't have band 17. so you are not going to get very good coverage in buildings or at far distances from the tower.

I didn't but I think cricket did it remotely when I put the SIM card in, how do I check? Also is it possible to unlock band 17? I've seen posts here and there talking about unlocking different bands on variants which don't have them unlocked by default. Thanks.

I know I had to put the APN settings in myself when using a T-Mobile SIM. I would Google "Cricket APN Settings" and then go to the settings on your phone (under more I believe), and edit the APN. You can't unlock band 17 unfortunately.

Yeah, why can't we unlock band 17? I tried using a few methods listed where you write to the NV ITEMS and enable all kinds of bands, but it still didn't work. I only got LTE when I force it via a hidden menu setting, but then I couldn't make or receive any calls. I get HSPA and HSPA+ but that's it and there's a constant icon in the notification bar of a white sim card with a question mark on it...!?

Because the phone doesn't support it. You can't unlock bands that the phone doesn't have to begin with.

Is there anything special to get calls to work on Cricket ? Updated APN settings for data but calls still did work.

When I tested with my Cricket SIM card calls just worked. I didn't have to do anything. However as you mentioned I had to manually update the APN to get data working.

That is odd. I wonder if I met someone at a Cricket wireless there if techs would help getting it working.

How to set network mode to 4G only?

Please help.. Is there a way to set network mode to 4G only or LTE only?... In settings, I only have the Autoconnect, 2G only and 3G only options.. Thanks..

Is your SIM card already 4G supported? What's your carrier?

The 4G auto connect is available? Apps might be able to access 4636 without root. In there, if there's an option, select phone information, then lock the RAT to 4G only. Alternatively, if *#2263# or *#2683662# is available, in *#0011# select the other SIM if there is any, then in those other codes, band selection, GSM ALL (for the unused SIM), change SIM again with *#0011#, band selection, LTE ALL(for the used SIM). What's expected: If the SIM is not a USIM, the RAT will stay on 3G(UMTS/WCDMA). If the USIM is not authorized, no signal. With soft PLMN locking (manual operator search) the signal level is shown but it's unusable. If the signal is still not available, maybe the phone does not support that band/frequency or no LTE coverage? If rooted it's possible to add LTE only in those settings in feature.xml, if that file is not available others.xml is used. Or launch 4636, or RIL service mode with am broadcast.

Use this app (no root needed). Set to LTE ONLY. Works fine.

This is worth a try. It's 4636.

ADD THIS IN system\csc\other.xml
<CscFeature_Setting_CustNetworkSelMenu4>LTEONLY</CscFeature_Setting_CustNetworkSelMenu4>
