To provide SMS service, we work with world leading independent SMS providers, as such users’ monthly SMS quota is not effected when we send SMS.

  11. Q: Is the Bluetooth connection stable?
    A: We have optimized how WISO and our app interacts. While we cannot change how well a phone’s bluetooth work, we have made sure that our app will always be able to receive WISO activation event when the two are connected, even if the app and the WISO are disconnected at the time of activation.

  12. Q: Does the app use a lot of battery?
    A: Under normal conditions our app uses very little battery. When an emergency event is active, our app will only update user’s current location every few minutes, which in our test using iPhone 6 Plus with iOS 9 uses only 2% of battery every hour. Therefore in most situations our app should be able to provide enough battery life for the duration of a typical emergency.
