Something which is strongly discouraged (you'd be supposed to contact law enforcement telling them that you've located stolen goods).
Notice that these devices are marketed as tools to find what you've lost. Never as anti theft devices.
Wait. You are the thread starter. So have you decided on the #notag option? I've never thought stolen bike tracking was a good idea. Anti-theft security strategies are where you should be putting your time and energy. If you are flying with a reputable airline and they lose or misplace your bike somehow they will have to find it or $$$ come your way. If your bike is lost any other way you likely would not find it while on the move on an international journey. So do not let that bike out of your sight unless it is under the airlines custody.
