Do I need a SIM card for my Curv Home Alarm System to work?
The Curv Alarm system can function two ways:
1. You can connect the device to a 2.4 ghz Wireless network, this will send you push notifications with any updates.
2. You can use a SIM card so the device will text / call you with updates instead of app notifications, the SIM will need to be pay as you go.
You can use either one of these options independently or both of them together.
