If you have a txt/pix package, it will take off the non-Verizon txt you have.
For example, I have the package that gives me the 500 non-Verizon to Verizon text's. Every time you send a text through Messenger or receive a text from Messenger, it will take away from the 500.
After the 500 is gone, it's 10 cent's per send and 10 cents per receive.
If you don't have the text package, then it's 10 cents per send and receive.
