We are working on a telematics (aka connected car) product. The system is similar to GM's Onstar. For data transfer between vehicle on-board unit and remote server, we plan to use GSM module with SIM card. The expected data amount is about 20 mb per month. What is a cost-effective way to do this (through a telecom carrier like AT&T may be too costly)? Or we can pursue other technology solution. Thanks.
