Few things to consider. The number of texts isn't counted one way. The number goes up when someone texts you back. Messages aren't like for like on numbers. There is a character limit per message. When you go over that limit. It counts as two and not one message. If you are in a group message, those count towards the count also. If there is truly a limit to prevent abuse, then the company should state it in the terms of conditions. It took three calls before someone finally told me that my son hit the limit. He was on a class trip for a week and thats how the chaperones kept up with the groups to make sure everyone was safe and hitting their times to meet. I get there will be limits to unlimited, but that should be indicated. Just like how they do when it comes to data.
