Just got my Razr today, and I had this problem on my last phone... Smaller text messages send fine and fast, but when I have a longer text, one that should span over a couple texts, it gives me the "Message cannot be sent" error. On my last phone I had handcent and there was an option to automatically split messages over 160 characters into multiple texts. using that option fixed my issue. I don't mind using handcent again but I like the looks of the stock text program. Anyone know of a solution?
