Whats the maximum number of characters you can send in a text using the

Motorola RAZR2 V9m.? Whats the maximum number of characters you can send in a text using the Motorola RAZR2 V9m.

I know some phones can send like 1000 characters in one text message (well you type it as one message on your phone but your phone splits it up and sends it out as more) but then theres other stupid phones that only allow you to type up to like 150 or 120 characters in one message . Oh and i'm with virgin if that matters.
