Just a little over a year after going to 15 cents per message, T-Mobile's at it again, bumping the rate to 20 cents for those who go over their monthly allotment. For anyone with an unlimited messaging plan, it's obviously not an issue -- but many folks aren't, so this could end up stinging the pocketbook just a bit when it goes in effect come August 29. For what it's worth, T-Mob just seems to be responding to the 20 cent trend that's going on in the industry right now -- but it still hurts something fierce, and it's a pretty solid reminder that even casual texters are better off on a legit messaging plan these days.
