what is the name of type of data cards that we once bought upon arrival at hong kong airport where we paid a certain amount of money for a certain duration etc and that the data will be increased and topped up everytime we click and like the advertiser or share the advertiser on our FB. I dont remember there was a HK mob number...i assume it was just a data card...for internet surfing and whatsapp etc... pls advise.
