@varkey I had taken static IP with KV. Paid 1500/- ( or 1000/- don't remember now ) as initial deposit for an year. I opted for static IP since I wanted to open incoming traffic in few UDP ports.
I was paying normal monthly charges ( 750/- or so). But some point of time an amendment came from
DOT that static IP should be provided to subscribers who will be paying more than 1000/- as monthly rent. Due to this KV created a new plan for 1001/- and I had to pay this rent. By that time my play with the UDP ports come to an end and I opted out static IP plan.
Things changed during lock down time , KV was so pathetic , then I switched to BSNL.
