Cinterion MC55i reports "SIM not inserted" after several use | Thales IoT Developer Community

July 11, 2014 - 2:37pm, 6957 views

Good morning, We are integrating MC55i in a system based of a Fujitsu RX100 Server equipped with Windows 2008 Server. This appliance is intended to work H24/7days. The purpose is to send SMS to well known recipients when a specified event is reported on the server. After 1/2 days of normal working (or in other cases in some randomic time) the modem reports "CME Error: SIM not inserted" and the LED is blinking 1 second (no registered to network). Obviously the SIM card is still inside the modem and nobody touched it. To solve the problem We have to restart the entire server and re-power the modem. Sim cards used are provided by "Vodafone IT" Do You have any suggestions/requests of details? Thanks in advance
