Trouble-shooting:

Make sure you've tested your sim card in an actual cell phone and it works. However, when you place that sim card in the sim card holder in this unit, Power Strip, Alarm Clock Radio,etc. and it doesn't seem to work. Please place the unit near an open window or door to make sure it tests out there ok first prior to placing it in the target location. Sometimes the signal doesn't quite reach the unit the same way cell phones signals work. So, you may need to try one or more different locations first. If possible, also try elevating the item off the floor to improve reception.

Note: Please send SMS ' 912 ' to the sim card to retrieve lost 3 digit pin code.

Note: It maybe necessary to place a small piece of paper in the sim-card holder along with the sim card in order to cause the sim's contacts to actually touch the copper contacts of the sim holder. Use this method after you've verified that the sim card is actually working by placing it in a cell phone and making or receiving a call on that same phone. Sometimes the sim cards contact aren't actually touching the sim holder contacts.

Note:

* The unit will call YOU when it hears sound or voices (approx. 15ft. or 4.57 meters).

* For Improved Audio Quality When Calling into The Device, Please Use an Earpiece with Your Cell Phone That Has Two Ear Buds. For Stereo Effect.
