I have been using MTS Mblaze for the past 8 months with 550 plan in Delhi area. It plan gives 5gb Day and 5gb night data. Day timings are 8 am to 12 midnight and night timings from 12 midnight to 8am
It gives fast quality speed though sometimes I face network issue.
I have post paid plan. In the beginning the customer care service was very irritating. After issuing the bill, they use to call me on daily basis and send SMS daily to remind me to pay the bill. But after making 2-3 payments in time, the irritating reminder calls and SMSs reduced drastically, perhaps they are not confident that I will pay their bills in time. Now, I only get reminders by SMS, that too, in the last week before the due date.
