We're heading over to the states in May with our two young boys. We'll be going to some busy locations and so I'm trying to think about ways to keep track of their whereabouts should we get separated somehow. An idea that struck me is to get a couple of cheap Android phones, stick a US SIM with a prepaid account in them once we get there, and then maybe sew them into a pocket or something.
Trouble is, I'm an iPhone user myself and am completely out of the loop on Android. Can anyone recommend such a device? It doesn't matter how crappy it is, as long as it is unlocked (so will take a US SIM) and has GPS. I don't intend the kids to really even know they're on them so they won't be using them.
In terms of an app, I'm aware of Life360 which is a cross-platform location tracker that we will be able to use on our iPhones. Open to suggestions for alternatives though.
Or if anyone has any completely different suggestions.
