No longer free unlimited calling/sms

This app used to be my go to app for free unlimited calling and texting to US mobile numbers. As of the latest update, I cant send or receive texts or phone calls to any number. Says I have zero credit balance and need 5 credits per SMS. I tried getting a new phone number assigned thinking that would fix things but they want me to pay for a new number. App is completely useless now. Cant call or text for free like I used to. Time to look elsewhere.
