Updates the eSIM's display name, tags, or metadata. Lifecycle and connectivity are managed through the dedicated endpoints.

Parameters

esim_idstring

eSIM ID.

Request Payload

display_name
nullable string

Free-text label for your own reference. Null clears it.

tags
array of object

Replaces the eSIM's tags.

Show child parameters
metadata
object

Replaces the eSIM's metadata. Maximum 2 KB serialized.

Response Payload

subscriber_id
nullable string
required

The assigned service user, or null when the eSIM has no person assignment.

id
string
required
status
string
required
mode
string
required
iccid
nullable string
required

ICCID of the eSIM profile. Null while no profile is allocated yet, for example when provisioning failed before allocation.

phone_number
nullable string
required

Phone number attached to this eSIM, in E.164 format, as the supplier reports it. Null while none is on record: a data-only plan comes with no number, and a plan that includes one reports it after provisioning.

capabilities
object
Show child attributes
order_id
string
required

The order that created this eSIM.

display_name
nullable string

Free-text label for your own reference, for example a traveler or order reference.

installation
object
required
Show child attributes
packages
array of object
required

Current data packages, one per purchase.

Show child attributes
zone_balances
array of object
required

Remaining data per coverage zone, combined across the zone's packages. Derived; the packages are the source of truth.

Show child attributes
available_actions
array of object

Actions currently available to you on this eSIM, with reasons for unavailable actions. Returned by the individual eSIM read. Use this to display controls and explain restrictions. Each action rechecks permissions and state when submitted, so availability is not a guarantee of success.

Show child attributes
available_actions.action
string
required
available_actions.operation
string
required

Operation to call for this action. Consult that operation’s reference for its request and response.

available_actions.available
boolean
required

Whether the action is available given your permissions and the current eSIM state. The action checks these again when submitted; a later request can be refused if conditions change.

available_actions.reason
nullable string
required

Why the action is unavailable. Null while available is true.

available_actions.requires
array of string

Additional parameters required by the current state, such as acknowledge_balance_forfeit when releasing an eSIM with remaining data. Absent when no additional parameters apply or when permissions, network support, or profile state prevent the action.

package_limit
integer
required

Maximum number of concurrent data packages this eSIM can hold, counted across all zones; several packages may share one zone. Enforced when packages are added.

usage_available
boolean
required

Whether daily usage history is supported for this eSIM. The daily usage endpoint is currently unavailable; read package balances for reported consumption.

balance_reporting
string
required

Whether ongoing package consumption reporting is available. Separate from daily usage history. Null package consumption values mean no measurement is available.

ready_until
nullable string

Activate (first network use) before this moment or the eSIM expires. Null once activated.

activated_at
nullable string

When the eSIM first used a mobile network. Null until then.

active_until
nullable string

When the eSIM's service period ends. The period starts at activation and data packages cannot outlive it. Null until activated.

last_attachment
nullable object

Most recent network attachment, or null before first attach.

Show child attributes
tags
array of object

Tags for routing, filtering, and stats grouping, echoed on webhook events for the eSIM.

Show child attributes
metadata
object

Your own key-value data, echoed on webhook events for the eSIM. Maximum 2 KB serialized.

created_at
string
required
updated_at
string
required
