Make a free messaging application that will make your messages sound friendlier and smarter. (Also, gramatically correct. Essentially, advertise it as “Grammarly for text messages”.) Keep it free until you get the majority of users. Then allow them to choose to pay a little money to make them sound even friendlier and smarter. Then gradually make the non-paid version sound normal, or even slightly hostile and stupid.
Actually, if you are Google, make this a standard Gmail functionality. You already have your users sufficiently locked in. ;)
