Later this year we're taking a trip to Europe with kids in tow. Call me a paranoid parent (the Mrs. does!) but I'm looking for a GPS tracker (preferably a watch or something wearable) where I can track where the kids are in case the worst happens.
I'm been looking online and there are a number of options, but I'm looking for one that hopefully doesn't require a subscription and definitely one that does need a SIM card/data connection.
Has anyone out there in geekzone ever done anything like this before?
