Yes! While Flare is currently only available for sale in the United States, it will work while you are traveling abroad, as long as your phone has cellular service. Please be aware that the Flare app and features will likely have a small delay while being used outside the United States. In addition, your phone must be logged in to the Flare app and have Bluetooth enabled. If you travel and change your SIM, you'll need to update your phone number in your account.
