How to fix 3G or 4G constantly dropping to 2G or Edge on an MTK Android phone

how to set an MTK Android phone to 3G only

It could be very frustrating rocking 3G or 4G only for that to be replaced by the dreaded Edge. It would’ve been understandable if this happened once a while but a constant tanking (dropping without rising) from 3G / 4G to Edge is not fun in any way.

Why does my 3G / 4G keep dropping to Edge

Possible reasons you could be experiencing this are:

  • Poor signal reception (network): The reception in your area might be poor or down
  • Surfing via a proxy: Using proxy APNs / tweaks could affect what signal your phone gets (data capping)
  • Phone settling for stability: Your MTK Android phone tends to settle for the more stable signal strength and might take longer (than you would want) to refresh

How do I revert to 3G or 4G from Edge?

Once the 3G or 4G signal is strong / stable enough, you should resume receiving it. If this however takes too long then you could speed it up by enabling then disabling Airplane mode under Settings > More > Airplane mode. Soft rebooting (restarting) and Hard rebooting (taking out the battery) could help. You should also consider changing your location.

How can I stop the constant tanks from 3G / 4G to Edge?

One technique that works for me is to set the phone to WCDMA only instead of GSM/WCDMA (since Edge is useless to me anyway).

Warning! Do not do this in an area without 3G or 4G as it would mean no signal.

There are two ways you could do this:

1. Under Mobile networks settings

  • Navigate to Settings
  • Tap More
  • Tap Mobile networks
  • Tap 3G service
  • Tap Network Mode
  • Set to WCDMA only
  • Your signal will go off then come back on

          Are you saying the phone is dead or its having 3G issues?

          • April 14, 2016 at 2:20 pm

            while flashing stock firmware with sp flash tools
            so i said that “no, i never faced any error while flashing”

            So you’re only having 3G issues right?
