Thanks, I'd forgotten that the Medallion can help me find him.
Definitely want to be able to communicate also. (Its like before he had his phone and we were relying on air tags. I could see that he and his bike were at the basketball courts, but it didn't get him home for soccer practice any faster.)
Can I buy internet buy the gig, or just a package for him? Since all he will be doing is texting, he won't use much data.
