Does it cost money to receive text messages on a virgin mobile phone?

[i <3 tom kaulitz.]

Because i dont have unlimited texting or anything like that. My mom isnt fond on me texting so yeah. I send my text messages through the virgin mobile website and i was wondering if it costs me money to recieve the messages back on my phone. Im planning to send through computer, recieve meesage on phone, and then send back through computer. Thanks!
