Hi,
What is a SIM Card breakout board? I saw one of these from a seller who usually sells SIM300, etc. modules. Without additional components, can the breakout board be used for simple communication - for example, to at least know a message has arrived and then trigger an action? Would it involve establishing connection, authenticating, etc. with the service provider too?
I am too tempted to try this. Would this component be worth it for a cost-contraint newbie with almost zero knowledge in protocols?
