Scam, I would give this app 0 stars if I could, callers can't hear me when I call and SMS messages don't come through at all. Not worth the hassle, also even if you pay the unlimited 9.99 mnth which is supposed to come with a phone number, but you have to pay an additional 4.99 mnth it. I couldn't find a phone number or email to talk to anyone and their support functions in the app only prompt me to send to my contacts. Waste of money.
