The Binding code in the Super-G i5 watch menu is intended for linking the watch to your Trackino account. If you scan this code before downloading the app, it will direct you to the app download page. If you scan the code within the app, the watch will connect to your account.
If there is no SIM card in the watch, the code will not be active, and you will not be able to pair the watch until a SIM card is inserted.
