This is not a trick, its a legal offer by airtel so we can activate in any balance.
just dial *888*1# and choose option 1 to activate , You will get the reply “ reply 1 to activate, free for 90 days”, reply with 1 and wait for 2hours.
Hurray you activated free MCA for 90days.
(after 90days just deactivate, and reactivate it again).
