Worst experience ever. Heres why:
The connection drops very frequently
Low speed. Only during late night, i.e., 2-5 AM I have seen some average speed.
Limited connectivity. As well known as it is, MTS has the smallest network coverage probably as compared to its competitors.
My monthly plan is of INR 999 with 24 GB of usage, but the service is so great that am never able to exhaust this data.
