Speed Class is a SIM-specific setting that allows you to control the amount of upload and download bandwidth available to a SIM.

When registering a SIM card (either by registering an order, or by using a SIM's ICCID and PUK), a default Speed Class will be applied to the SIM at the time of registration. For Soracom IoT SIMs in Global coverage, the default Speed Class is s1.standard.

With this update, the default Speed Class applied to IoT SIMs in Global coverage during SIM registration will become s1.4xfast.

Rest assured that data usage costs in Global coverage remain the same regardless of a SIM's speed class. Instead, data usage costs are determined only by each country's data usage fees, as well as any applicable pooled data usage tiers or volume discounts.

Effective date

This update will take effect on October 28, 2021.

Note

This update will only affect IoT SIMs in Global coverage that are registered on or after the effective date above. Speed Class settings for existing SIMs will not be modified.

Please note that a Speed Class setting only controls the maximum available bandwidth. Actual bandwidth may differ based on other conditions, such as signal quality or device settings.

Additionally, while data usage costs remain the same regardless of speed class, the additional bandwidth may potentially allow devices to consume more data, and therefore accrue more fees, if not sufficiently controlled. You may prefer reverting to a lower speed class in order to limit a device's ability to use large amounts of data.

For details on the amount of bandwidth provided by each Speed Class, or for instructions on how to change a SIM's Speed Class setting, please refer to the Speed Class documentation.
