Can I add satellite connectivity to an existing Soracom SIM, or do I need a new one?
You do not need a new SIM. Satellite connectivity (planNT1) can be added over the air to existing plan01s or plan-US SIMs using Soracom's Subscription Container technology, provided your device has a compatible radio module.
What are the typical message size and frequency limitations when using Soracom's satellite NB-IoT connectivity?
Satellite NB-IoT is optimized for small, meaningful IoT messages. Payloads should typically be kept to 50–256 bytes, and messages are best sent periodically or event-based, roughly at a maximum of 20 packets per minute in typical designs.
How does Soracom handle data routing and protocol conversion for devices using satellite connectivity, especially if they need to send MQTT messages?
For satellite NB-IoT, it's recommended to use device-side UDP. Soracom Beam can then convert these UDP packets to HTTPS or MQTT before routing them to your chosen cloud endpoint, avoiding the complexities of direct MQTT over satellite.
Is Soracom's satellite connectivity designed to serve as a backup for broadband internet access?
No, Soracom's satellite connectivity (planNT1) is specifically designed for small, periodic IoT messages and is not intended for high-bandwidth applications such as broadband internet, video streaming, voice calls, or SMS.
What kind of radio modules are compatible with Soracom's 3GPP Release-17 NB-NTN satellite service?
The service requires R17-capable NB-IoT modules from vendors such as Murata, Quectel, Telit, Sierra, and Blues Wireless. It is advisable to check the current certified list before ordering modules to ensure compatibility.
How does Soracom ensure security for IoT devices connecting to private networks or cloud environments over cellular?
Soracom provides secure by design features like Virtual Private Gateway (VPG), Canal, and Door. These allow you to connect private networks, VPNs, or cloud environments over cellular securely, isolating traffic from the public internet without the complexity of private APNs.
