Thanks
@Siva,
@Raja and all bros who helped me here. I was able to get my Basepack changed to MyPlan 99 w/o any TopUps, and I added the free regional topups myself. For the interim period from now to 01-Feb-2019, I believe it is best to stick to the lowest pack instead of paying hefty DBR charges (I was always a ARP Customer, so never paid in DBR till now).
Just hoping that ADTV comes up with good attractive plans - will surely opt for the same.
@Gobinaath bro provided some good insights on upcoming plans - hoping for the best for ROI region too.
