    Great app. 20-30 euros per month. Pays off.

  • S

    This is the best SMS testing app for passive income. There is the possibility of 45 euros per month! The SMS messages don't notify, or cause "unread" msgs. The messages are extremely unintrusive and they pay out within the first 7 days of each month. I've tried other apps like this, but none have produced as much $$ as this app, not even close! Great app, love it. Get it! It's like free money!
