Points to Note

  1. 3G/4G LTE only mode is necessary only when there’s a poor WCDMA/HSPA+ coverage in area; thereby causing the network to fluctuate between 2G and 3G signal.
  2. Most dual SIM card devices allows you to use either SIM1 or SIM2 for 3G Network and not both for WCDMA data. You can use SIM1 as 3G (WCDMA/4LTE) and SIM2 as 2G (GPRS/EDGE) or vice versa.
  3. 4G LTE data network coverage is not as wide as that of earlier generations (ie- 3g, gprs, edge and hspa+). This might cause you to lose coverage often while using the 4G LTE only network signal mode.
  4. Voice calls and regular text messaging (SMS) features do not work on 4G LTE only mode.
  5. Phone information1 stands for SIM Card 1, while phone information2 stands for SIM Card 2.

Best 4 Methods to Force 3G/4G LTE Mode on Android Devices

Here comes the main topic of discussion, forcing 3G/4G only mode on Android devices. The 4 tweaks looks similar as it gears towards granting you access to the “phone information space”. I’ll advice you go with the method that’s very easy for you as most devices will reset the configuration after a restart.

1. Using the Internal Memory Exploit

This is the easiest method from my viewpoint, as it can be completed in seconds and without much efforts. So here comes the tips to force 3G/4G LTE only mode on Android by tweaking via internal memory exploit.

It works flawlessly on Xiaomi Redmi devices and other Chinese smart phones (MTK powered cell phones) such as Tecno, OnePlus, iTel, Wiko, infinix, innjoo, HTC, Huawei, ZTE, Lenovo, Ulefone, Acer, Asus, Mercury, Micromax, Vodafone, iBerry, Elephone, Orange mobile, Benefon, i-mobile, Meizu, Alcatel, Gionee & etc.

Step1: Go to settings and click on About phone.

Step2: Locate Internal Memory and click on it four (4) times.

That’s all. Your device is now configured to 3G/4G LTE only mode.

2. Using the Dialer USSD code Exploit

This is another easy method for setting 3G/4G only mode on Android devices. It is as easy as dialing some set of USSD codes on your phone dialer.

The general USSD code to dial for this tweak is *#*#info#*#*, but most devices would need you dial any of the other USSD codes below.

To force 3G only mode on android devices via the USSD code exploit, you’ll need complete the following steps.

Step1: Dial any of  *#*#4636#*#*, *#*#2846579#*#*, ##626* OR ##786# (depending on which works for your device model) on your phone dialer and follow after the pop-up window’s options.

Step2: Click on Phone information1 ==> set preferred network type  or Project menu ==> Network settings ==> network mode set to complete the 3G/4G LTE only mode settings.

3. Using 3G Only Network Mode App

This is another effortless method to forcefully set WCDMA/LTE only data connection mode on Android devices. The app lets you dial the right code for your phone model and then completes the 3G/4G only data mode.

To enable WCDMA/LTE only mode with this method, you’ll need download the app from Google play store link (, install  and complete from the on-screen prompt.

4. Using Engineering apps

This is the most advanced, going from how easy and effortless the other three methods are. The engineering app to install depends on the phone type you’re trying to set the 3G/4G only network on.

For Mediatek (MTK) processors, install the MTK Engineer App from Google play store ==> launch it and navigate to Android settings ==>  Telephony.

Locate the network options and set the preferred network mode. Note that Mobile Uncle Tools can be used in place of MTK Engineer app.

For high-end devices with Qualcomm processor, install the Shortcut Master app from Google play store ==> launch it and navigate to Menu.

Search for Service Menu/Engineering Mode and complete the Protocol Configuration ==> NAS ==> Network Control ==>Band Selection ==> preferred LTE Band.

Other engineering apps can be used as well by following after their  instruction to tweak accordingly.


These 4 methods are best for setting 3G/4G only network mode on Android devices. They can be used in areas with spotty WCDMA/LTE network coverage and works for MTK and/or Qualcomm devices alike.
