this app was fine and really helped me during times of low or no service from my usual carrier, so i paid to keep my number and remove ads. now all of a sudden is a message saying ive exceeded the daily limit for fair use of outbound domestic texts. what the hell does that mean? no where anywhere on your website or anywhere else do you mention limits on texting or fair use stipulations. you advertise FREE calls AND texts worldwide. period. it was fine, i never had a problem until i paid for it.
