Unable to open service/engineering mode

[piyush4542]

Hello everyone.. i want to force switch on LTE mode on my device to use 4g internet and sim. I know it will not convert device to 4g.
But to that i have to open engineering mode. U have tried mtk engineering app and ussd codes *#*#197328640#*#*
But unable to open the menu. App says "can not find engineer mode app"
I have followed the following steps http://flipshope.com/blog/how-to-use-reliance-jio-4g-sim-in-3g-phone/

*#*#4636#*#*
