I had enough of SIFY's plans, only god knows how I managed to use their plans for about a year or so.I frequently changed between Unlimited 256 night, full 256, Unlimited 128 night,96 unlimited.I believe i had never used the same plan for more than two months 😀 😀 . Changing to AIrtel in a few days , was just waiting for rains to get over in chennai before I switch B) B) .Good bye Sify.
