What is the length of my plan?

How is the IoT SIM included in RFI’s 4G SIM and Modem Bundle Packs different from other SIM cards?
- No call, no SMS. These SIMs are specialised for data only applications.
- Hosted on a private network with an Access Control List (ACL).
- Due to the ACL, the IoT SIMS cannot access the wider Internet, they can only access websites that have been specifically allowed by RFI.
- Hosted on the Vodafone dedicated IoT Network for a more robust service.
Why is the IoT SIM included in RFI’s 4G SIM and Modem Bundle Pack the perfect solution for inverter monitoring?
- Increased security due to the ACL.
- Lower chance of phishing or hacking, lower chance of bill shock due to unauthorised access.
- The robust network due to the IoT core, means more uptime, and better support to keep you up and running.
- With RFI able to monitor, report and manage your service you always have the support you need.
