I've already got cricket account,I've got a phone i want to switch,how do i do it

Hey @bbg2019 , if the new phone has the same sized sim slot as the old one you can just put your sim in the new phone. Keep in mind that the phone needs to be  Cricket phone, AT&T phone, or unlocked phone or it won't work. You also may need to adjust the APNs if it is an Android.
