Yesterday, I received my SimpliSafe system and installed it in the evening. I enrolled in the $24.99 monitoring plan when I placed my SimpleSafe order.
Setup went smoothly and I understand how to enter test mode and that putting my system in test mode is supposed to send a signal to SimpleSafe so that it can "see" my base station and so that I can log in to view my control panel (and ultimately use the phone app to use all the features available there).
