Moto G network type (3G) problem ? Solved !!!

Unable to switch back to 3G from 2G on Moto G ?

Question Title:

Unable to switch back to 3G from 2G on Moto G

Below is the scenario:

After toggling the Preferred Network from 3G to 2G the Moto G doesn't let us change it back to 3G.
When toggled back to 3G, it stays on 2G and 'E' symbol is still shown on top of SIM.
I know it's annoying and a small bug indeed.No worry we have a solution.

Solution:

Method 1 (Works for some people) :
1.Open the Dialer and Dial *#*#4636#*#*
2.Tap On "Phone Information".

3.Scroll down you can see "set preferred network type"4.Change it to "WCDMA preferred".

5.Do not touch any other settings and come back to home screen.

Method 2 (Works everytime) :
1. Disable the secondary SIM :
    Settings > Dual SIM Settings > OFF the sim that you don't use for Data.
2. Change Network Type:
    Settings > More... > Mobile networks > now change "Preffered network type" to 3G (for the sim         that you use for data).
3. Enable the secondary SIM back:
    Settings > Dual SIM Settings > ON the sim that you don't use for Data.
