Can you use an AT&T phone with an T-Mobile Simcard?

[Ciara]

My family had an T-Mobile plan but I really like this phone from AT&T. Can you use the simcard from T-Mobile and put it in an AT&T Phone? And I also heard something about unlocking and if you unlock something, you can't text. Is that true about the not texting?
