You will need to set up the overseas number in the Contact through the App so your Angel Watch can call overseas numbers.
Your Angel Watch™ included SIM (USA only) even has free calling to 80+ countries including other North American countries like Mexico and Canada!
Please save numbers with the country code preceded with a plus (+) sign.
For example, if you wanted to call family in Mexico, you would enter that contact into the phonebook of the app at +525551231234.
