Hi Friends,I'm currently using an Airtel 128 kbps Unlimited plan. I have noticed many people on this forum talk about double speeds at night. i.e., 12-14 kBps during day and 20-22 kBps during night. How do you folks get such speeds - have you opted for a nightly top-up plan or are you getting it for the normal 699+taxes plan itself?Also, i'm considering migrating to a faster unlimited plan. What to you suggest? Shall i go in for the 256 kbps Unlimited plan - can someone tell me how much exactly it would cost per month? And are there any other better alternatives? Thanks!Cheers,William.
