Overview

Soracom's enables IoT devices to connect to Skylo's NTN (Non-Terrestrial Networks) satellite network using NB-IoT (NTN R17). Built on Soracom’s Connectivity Management Platform, delivers satellite-based coverage to regions that traditional terrestrial networks cannot reach, including rural, remote, or maritime environments.

Features

• Satellite-based NB-IoT (NTN R17) connectivity via Skylo.
• OTA (Over-the-Air) provisioning to and IoT SIM cards using Soracom’s Subscription Containers feature.
• Operates on standardized NB-IoT bands (availability depends on regional satellite coverage):
  • Band 255 (1525–1660.5 MHz) – UK, Australia, New Zealand, Brazil.
  • Band 256 (1980–2200 MHz) – Europe.
  • Band 23 (2000–2200 MHz) – North America (US, Canada).
• Designed for low-power, low-bandwidth applications.

Coverage

provides both satellite and cellular coverage.

Satellite Coverage

Satellite coverage via Skylo is available in:

• The United States, Brazil, and Canada.
• Multiple EU countries and the United Kingdom.
• Australia and New Zealand.

Additional countries will be added as satellite coverage becomes available. Refer to Skylo’s coverage map or contact us for current regional availability.

Cellular Coverage

also includes 2G, 3G, 4G/LTE, LTE Cat-M1, and NB-IoT cellular connectivity in over 90 countries. For a full list of supported countries and carriers, refer to the Supported Carriers page.

Device Requirements

Devices must be certified for use with the Skylo network. Soracom has independently validated the following modules:

Please refer to the Skylo certified devices list for more information on certified devices.

Limitations

When using , please keep the following limitations in mind:

Connection-oriented or synchronous protocols, such as TCP, HTTP, and MQTT, should be avoided when using a satellite connection. Timeouts and retransmissions may occur due to these protocols being unoptimized for the high latency of satellite communications, which can result in communication failures and unexpected high data charges. For these reasons, Soracom recommends only using UDP traffic over satellite.

• When communicating via satellite, the maximum UDP payload size is 1200 bytes.
• When using with a Virtual Private Gateway, satellite connectivity is only supported if the VPG Rendezvous Point is configured as Frankfurt.
• SMS is not supported over satellite connections.
• Unlike other Soracom plans, will never be activated automatically for fallback. The IMSI must be selected manually by the user or explicitly configured in device settings.
