What should I do if I can't send and receive GSM messages and CDMA messages?

Passenger e-pass product is a system that China Telecom successfully applied to vehicle monitoring and management on a large scale by using CDMA wireless data communication technology. Through the innovation and combination of GPS, CDMA, GIS, Internet and MIS, we can realize the supervision of vehicles in the aspects of accurate positioning, violation alarm, continuous transmission of blind spots, track playback, rule setting, image transmission, mobile phone inquiry, theft and police contact, operation analysis, performance statistics, management decision support and so on. Passenger E-Pass can't send and receive GSM messages or CDMA messages, which may be because the car is in the blind area of CDMA signal, leaving the blind area or observing it after a while.
