I would contact AT&T and let them know that the phone is lost otherwise you may end up with any calls made on the phone. S13 took then h's phone on a fieldtrip, lost it and in the couple of hours before it was reported, several calls had been made. Once I reported it, they couldn't use that sim card anymore. I would at least talk to them. I know, like you don't have enough going on already!!
