The Arduino SIM service is provided by Arm Pelion Connectivity Management, meaning that one physical Arduino SIM is able to be used in over 100 countries with a single data plan. The Arduino SIM data plan is launching initially in the US, with European and Asian availability to follow in summer 2019. The service will allow users to send sensor data to databases, spreadsheets or alerts, without any coding necessary, using Webhooks, or create custom IoT applications using the API.
Arduino SIM will roll out with support for Arduino MKR GSM 1400 (3G with 2G fallback) – a 32-bit Arduino board supporting TLS and X.509 certificate-based authentication through an on-board secure element and crypto-accelerator. Arduino IoT Cloud makes it possible to connect securely without any coding required. They remain programmable using open-source libraries and the traditional Arduino IDE. A roadmap is in place to support the upcoming Arduino MKR NB 1500 (LTE Cat-M and NB-IoT), with plans to open it to third-party cellular boards at a later date.
Arduino SIM provides 10 MB of data free for up to 90 days, and then a simple subscription at 5 MB for $1.50 USD per month. The partnership with Arm Pelion Connectivity Management brings a solid foundation for users planning to scale to large numbers of devices in the future.
