I would have rated this 5 stars before, I've been using this app for well over a year and it's been my only method of communication with others, and it's been good. the ads have always been annoying, but i don't mind. The reason why i've changed my rating from 5 to 1, is that now, I cannot recieve verification codes without paying $5 per year to lock in my number. Ridiculous, because i CAN'T, as I don't have a credit card, and because now i have no way of getting codes to log into accounts! thx!
