There may have confusions on my Whatsapp contact.
As I used to have two Philippine numbers for
Since I shuttle between Manila and Hong Kong.
If you use Philippine SIM, it is very expensive even though you turn off your Data or Data Roaming, as once you turn on your phone overseas, they WILL not care and charge you Peso 550 a day (HKD$98)
I consulted some Phone gurus, they advised me either Remove the SIM card or go to Airplane mode when I am in HK.
So you can now Whatsapp me to my Smart Philippine Number +639989811111.
