Soracom Air for Cellular

Expiration Function

In some applications, you may want to end your device's data session or suspend or terminate your subscription at a pre-determined date and time. The Expiration function allows you to set your IoT SIM to perform a one-time action.

Expiry Actions

The following actions are available when setting an Expiry Action for an Air subscriber:

When setting the Do nothing or Delete session actions, the subscription status will not be changed. Any daily basic fees associated with the existing status will continue. The Expiry Action date and time must be cleared or extended in order for the subscriber to establish new connections.

When setting the Deactivate or Suspend actions, the subscription status will be changed to Inactive or Suspended, respectively, at the specified date / time. Any daily basic fees for each status will apply according to the subscription plan. The subscription status must be changed back to Active and its Expiry Action date / time must be cleared or extended in order for the subscriber to establish new connections.

When setting the Terminate action, the subscription will be permanently terminated at the specified date / time. The subscription cannot be re-activated and no further connections will be possible.

Programmatic Usage

You can also use the Soracom API, Soracom CLI, and Metadata Service to enable or disable expiration.

Soracom API

To access the Soracom API, first use the auth API to obtain an API Key and Token. Refer to the API Reference Guide for instructions on how to use the API Key and Token in API requests.

Then, use the setExpiryTime API to enable expiration on an IoT SIM:

curl -X POST \
>  -H 'X-Soracom-API-Key: <MY-API-KEY>' \
>  -H 'X-Soracom-Token: <MY-TOKEN>' \
>  -H 'Content-Type: application/json' \
>  -d '{
>        "expiryAction": "deleteSession",
>        "expiryTime": 1704067200000
>      }' \
>  https://g.api.soracom.io/v1/subscribers/<IMSI>/set_expiry_time

To remove expiration from an IoT SIM, use the unsetExpiryTime API:

curl -X POST \
>  -H 'X-Soracom-API-Key: <MY-API-KEY>' \
>  -H 'X-Soracom-Token: <MY-TOKEN>' \
>  https://g.api.soracom.io/v1/subscribers/<IMSI>/unset_expiry_time

Soracom CLI

To use the Soracom CLI, you must first configure it to authenticate with your account information, authorization key, or SAM user credentials.

Then, run the following command to enable expiration on an IoT SIM:

soracom subscribers set-expiry-time --imsi <IMSI> --expiry-action "deleteSession" --expiry-time 1704067200000 --coverage-type g

To remove expiration from an IoT SIM, use following command:

soracom subscribers unset-expiry-time --imsi <IMSI> --coverage-type g

Metadata Service

The Metadata Service allows an Air SIM device to access and configure its own settings without the need for authentication. For more information, refer to the Metadata Service documentation.

Because the Metadata Service allows an IoT SIM to access its own subscriber settings, this can be used as part of an initialization script so that a device sets its own expiration when it connects to a network for the first time.

To enable expiration on an IoT SIM, the Metadata Service Readonly option must be disabled. Then, from the IoT SIM device, use the setExpiryTime API:

curl -X POST \
>  -H 'Content-Type: application/json' \
>  -d '{
>        "expiryAction": "deleteSession",
>        "expiryTime": 1704067200000
>      }' \
>  http://metadata.soracom.io/v1/subscriber/set_expiry_time

Since the subscriber will be online, you can also omit the payload in order to lock the subscriber to its current IMEI.

To remove IMEI lock from the IoT SIM, use the unsetExpiryTime API:

curl -X POST http://metadata.soracom.io/v1/subscriber/unset_expiry_time
