Recently, I've encountered a problem with the wireless router "Dlink DWR-932C".
The Battery LED is always blinking with purple color which means it received an SMS, but it does not show the SMS in the inbox. I also deleted all the SMSs in the inbox, and reset the device, but it is still blinking in purple (When I use another Sim card the LED blinks in the normal color). How can I fix this problem?
