UK telecoms operator BT is offering a “new” national roaming service for IoT SIMs on its EE mobile network, plus on infrastructure managed by UK telco rivals and rented by partner MVNOs “where required”. The service will connect to traditional higher-powered M2M-style cellular 2G, 3G, 4G, and 5G networks, plus dedicated low-power wide-area (LPWA) NB-IoT and LTE-M networks, as suitable and available.
