    Default 2G, 3G and 4G - how do I determine what my module is capable of?

    For my latest project, I'm using a SIM800L GSM module.

    But what is telling me what networks (2G...4G) it is really capable of?

    The module's datasheet isnt' clear enought to me so I have doubts about its capacity of 3G and even 4G. I can only see it is "GSM 2/2+" compliant, so what in final?

    Can someone explain how I shall make the difference please?
