      Do the Deutsche Telekom SIM Chips work with all radio standards 2G,3G, LTE CAT-M1, NB-IoT or do I need for NB-IoT a different SIM? 🤔

      I have a Deutsche Telekom M2M SIM Chip, that I have been using now for many years and now I could confirm myself that it also works with LTE CAT-M1🙂 , but registration is denied for NB-IoT 😞 .

        Hi @Wolfgang6177 ,
        If you have a DT tariff that includes LTE/4G, then you may also access our LTE-M network. Yet for NB-IoT, you need a dedicated Multi-Mode tariff and SIM-card (Global SIM).
        Please follow this link for more details.
        Kind regards, Ronan
