NTT Communications (NTT Com) can use multiple carriers with one SIM, and when a failure occurs in one carrier, the SIM can autonomously switch the connection destination to the other carrier. Succeeded in developing Multi-access SIM. This SIM is a SIM for data communication, which is mainly assumed to be used for IoT. Since functions related to communication status monitoring and switching are included, the terminals do not need monitoring and switching functions. Therefore, it can be used on a wide range of terminals without depending on the model. Easy carrier redundancy even in cases where you want to implement carrier redundancy with existing terminals without purchasing new dedicated terminals or developing functions, or in cases where it is difficult to adopt multiple SIMs such as small IoT devices. be able to.

NTT Com will provide a trial for IoT from June to September. They plan to provide commercial services in “IoT Connect Mobile Type S” within FY2023.
