I'll never forget the time I used free text from PC to phone to send a message to my friend during a concert. We were both at the same venue, but we were on opposite sides of the arena. I was able to send her a message and we were able to meet up during the intermission. It was so cool!
Another memorable moment was when I used it to send a message to my family during a power outage. We didn't have any cell service, but I was able to use my computer to send a message and let them know we were okay. It was a total lifesaver!
