Google voice?

[oisact]

I use it to send and receive texts from my laptop. I never text from my phone when I'm at the computer. It also lets you "hide" your real cell number by only giving out your GV number, which for all intents is disposable. I use US Cellular and have unlimited incoming minutes. So I use GV to place calls, thus it calls me first, then connects me to whoever I'm calling. Thus all calls are incoming and are unlimited for me.
