What is the length of my plan? 

RFI’s Bundle Pack data plans are for one year. At the end of each year the plan can be renewed.

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. 

I am looking at making changes to my plan, what do I do?
