I have an old data SIM card bundled with my home broadband being unused for very long. Today I gave it to my son to use on his dual SIM Zenfone. Upon experimenting the thing, I discovered SMS can be sent through the data SIM card (SIM 2) too besides the prepaid HI card (SIM 1). How come? And how they'll charge it???
