Don't sweat it out....! 

There's a solution... 

Settings / storage / internal storage / apps / settings / clear data

Enjoy... Hope it helps...!

Re: Preferred SIM for Mobile data not changing

I have the same issue. I have SIM 1 - JIO 4G & SIM2-Vodafone 4G Sim. The problem started with 4G service of Vodafone. Tried to switch the preferred SIM for mobile data many times but Vodafone shows 4G signals fluctuating.  Replaced Vodafone SIM but it is in vain.

Tried suggestion was given by Mr. Chinmaya but the issue still persists. 

Now both networks are disappearing and reappearing periodically. Preferred SIM for Data option locked on Vodafone SIM and just shows "Data subscription change in progress" and nothing happens when trying to change it.

Any solution apart from "clear Data"?
