Is it possible to use a at&t prepaid phone chip in my Metro pcs Lg K7 phone?

I use to have at&t previously, but I figured that I would give Metro pcs complain a try since I was under the impression that they would be more cheaper. Long story short, needless to say I am not happy at all with this complain and I'm stuck using the Lg K7 phone I got through them until, I'm able to find a better phone, but I was wondering if it would be possible at all for me to use a prepaid phone chip in the phone I currently have at the moment?
