My pack is valid till August.
Yes, you are partially right. It's validity is 30 days so it would have not continued till August even if I would have activated it yesterday.
By the way, ROI HD Upg Bonanza topup is having a long validity, I'll continue with that
I am sure if airtel will give any free topups with HD upgrade or ARP or new connection in future, we all will be able to enjoy that
