Can't even create an account without first giving them your personal phone number. Very scammy, don't trust them. Well i guess since their reply says they use your native phone number to connect, then they aren't really a 2nd line are they? Regarding TextFree app, they don't tell you up front, but you can't receive a verification text with the free version, which means they are reading your texts before you get them. For your own protection of course - again, complete disrespect for privacy.
