Phones for kids - what do you have?

Hi all,My 8 and 10 yo kids are biking around the city more and we are leaving them home alone more and more (while I run an errand, or something. Nothing major). I'd like to get them a phone to use in emergencies or if they're lost, but I don't want to add to our already large phone bill. We have AT&T and we already carry my SIL on it.My husband saw a flip-phone that's $15/month through AT&T (Go Phone? I think?) but I'd rather not add to our already large phone bill.Is there a phone that's only pay-as-you-go? What do you use for your kids? via /r/Parenting http://ift.tt/2oaCpA4
