How to Force 3G (WCDMA only) or 4G (LTE only) Mode on Your Android Smartphone

I will be showing you a way you can force 3G WCDMA or 4G LTE only permanently on your smartphone. The only downside is that if you are in a location where 4G or 3G isn’t supported, you may not have network coverage.

These two codes below will work the wonders but may not be applicable on all smartphones.

1. *#*#4636#*#*
2. *#*#2846579#*#*

How Can I use the First Option?

1. Type *#*#4636#*#* using your dialer and you should be presented with a menu as seen below;
2. Click on Phone information (If your phone supports dual sim, phone information 1 is for sim 1 while phone information 2 is for sim 2)
3. Scroll down until you see a drop down menu where you can choose WCDMA only or LTE only

Once you select your option, go back and you are good to go.

How Can I Use Option 2?
Type *#*#2846579#*#* using your dialer and you should be presented with a menu. Select ProjectMenu.
Choose Network setting>>Network Mode
Select 3G only or other wise and you are good to go

Option 3

In the case where the two codes above doesn’t work for you, you can download the app. The app lets you dial the right code for your phone model and then completes the 3G/4G only data mode.

Download the app at Google play store link (https://play.google.com/store/apps/details?id=network.wcdmaonlymode.only3gswitch&hl=en)

Install it and complete the onscreen prompt.
