I got 3g+ data card with plan 999 for one year back, initially they give 40GB data usage, now reduced to 30GB, they cheating customers. From the first day I got worst experience their service. I have lot of bitter experience from their customer service. their network totally worst.
I asked their customer service datasheet for usage, but they did not respond, they give wrong direction. most of the places they have not tower. if you want to got most bitter experience take MTS.
