[Q] Att Galaxy S5 lollipop update while using Cricket service

I'm currently using a At&t branded S5 on cricket. I've tried to update with no luck and after reading here noticed I'm not even on the latest firmware. My S5 is running 4.4.2 and not 4.4.4. Am I able to receive the update? Can I force it in anyway? What are my options as far as getting the update?
