    GSM (Global System for Mobile Communications) is a wireless technology to describe protocols for cellular networks used by mobile phones with over 80% market share globally.

    LTE (Long Term Evolution) is a wireless broadband technology for communication of high speed data for mobile phones.



    The main difference between the technologies is that both CDMA & GSM can support cellular and data, whereas LTE can only support data.
    It means that if the phone does not have CDMA/GSM technology then the cellular (voice) services would NOT work, only data. good day ;)

    640 GSM would top out at H+ data speeds...

    640 LTE will add an LTE radio, naturally.
