It works (but "8" might vary); I also added optional "+" (and referenced your answer).
Please see.

Thanks for the 5. I went through your answer.

Solution 2

\+91[7-9][0-9]*

You can also make "+" optional:

\+?91[7-9][0-9]*

Combination with the feature shown by Abhinav will add constraints of start and end of line and number of digits (8 or any other):

^\+?91[7-9][0-9]{8}$

Or you can add optional blank space or "-". Do you need this as well? The idea is the same.
