Cricket Nokia Lumia 640 XL

Hello @chubbycatdog!

Thank you for reaching out to us on the Community Forums! I’d be delighted to help out with your question.

You may use your current AT&T SIM card in the Cricket phone however; the phone will need to be unlocked from their network first. You can reach out to them directly to check if it is unlocked already or what steps you would need to take to do so.

I hope this answers your question! Have a great rest of your week.

Donna, AT&T Community Specialist
