I would suggest skipping the LTE feature as it is better to use any phone as mobile hotspot instead. LTE is too costly.
Going for more RAM + better processor in that budget is a better option in my opinion.
That's 17k+extra for cover and screen guard - a little over my budget.
Right now I have shortlisted Nokia T20+cover+screen guard for 15.8k....
Waiting for deals to start...
