I hope these tricks is working for everyone. Sometimes if you are lucky then you got lifetime service. But sometimes Whatsapp service period only extend for 1 year or may be for 10 years.  But we does not guaranty about it sometime it may not work depend upon you luck and right time. Then i request you to pay little bit amount of $0.99 via PayPal or any other available method.
