This is a trick to receive any 1 Channel for Free.

First you should note the time of last recharge and calculate the date in which the subscription will be lost.
Tune into the channel which you want to get freely.

On the date of subscription lost and at the time of the last recharge, When half an hour is past try changing the channels. All the channels excluding the one you tuned will be lost. If not tune in for another one Hour.

Enjoy!
