Is there any way to text free through your stock android messanger app?

[AC Question]

Ok so I have textfree. I've used it for a while and its been good, but lately some of the updates theyve put out recently havent been running too smoothly on my phone (Motorola Atrix HD). So I was wondering if it is possible to somehow use a plugin and text for free through your stock messenger app such as Google Messenger, which runs a lot more smoothly on my phone. I don't mind not having the option to call, but I would like to text though. Basically what I'm asking is that is there anyway for me to use my stock messenger app as textfree? Thanks
