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.
