Not sure if this is the correct forum, but....I am in the market for a new GSM Gateway, ie a "Fixed Cellular Terminal is a device which reduces costs when calling from a fixed telephone line to GSM network" and I am not sure what to buy. Are all GSM Gateways the same, in that do I simply put the SIM card from the old unit into the replacement unit and do I need to do any configuration or are they plug and , so to speak? If they are not the same how do I know what I want, what to look for in the specification?
