its free for a year on android then either 99p or 99c. On apple you pay up front but then no subscription charge. TBH, for 65p or 99p I just paid, its so widely used by my friends and family its saved us that in phone calls in the first week.
I kept on getting the "pay for it" pop up. Then it wouldn't allow me to respond to people for a few days... all of a sudden it does. I still haven't paid for it yet its allowing me to send messages. Seems to do that for a few days a month but most of the month its acts as normal.
Still haven't paid for it .... roud::banana:
