It’s hacky as all hell and your battery life will be terrible. But it works.
While testing the Apple Watch Series 3 GPS + Cellular last night, I floated a crazy idea past iMore editor-at-large Rene Ritchie: What happens if you set up the Apple Watch on an iPhone, then swap that iPhone’s SIM card over into an Android phone? Would the watch recognize that its paired iPhone SIM was no longer in an iPhone and stop working? Would it still work over a carrier’s LTE connection?

And you likely won’t be able to access certain features like calling internationally or sending and receive SMS messages from your watch.

It took the Android device a few minutes to reboot and connect to AT&T. During that time, my watch showed a depressed “Disconnected,” though
