Alot of call blocking being done with My phone number and AT&T… no wonder the call block application is free of charge. AT&T ( it’s important to leave a voicemail message! And get seated properly in the contacts phone book Otherwise I’m blocking your call ) hi!my name is and you’ve reached my number @……. I’m unable to pick up your call right now. If you leave your name and phone number with a message… I will get back to you as soon as I can… thanks.!
