Resumes a suspended eSIM so it can use data again. Completes asynchronously; the esim.resumed webhook event confirms it. Resuming an eSIM that is not suspended returns a conflict.

Parameters

esim_idstring

eSIM ID.

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

Lifecycle state of an eSIM. A pending state always settles: to its target on success, or back to the prior status when the network definitively rejects the change, reported by the esim.operation_failed event.

  • provisioning: the initial data package is being applied; install credentials may already be available.
  • ready: installable and usable, waiting for first network use; allows top-up orders and release. Activate before ready_until or the eSIM expires.
  • activating: an activation is being applied.
  • active: in service; the service period ends at active_until. Allows top-up orders, suspend, resync, and release.
  • suspending: a suspension was requested and is being applied.
  • suspended: data service is paused; allows resume and release.
  • resuming: a resume was requested and is being applied.
  • releasing: a permanent release is in progress.
  • released: permanently released; terminal.
  • expired: dormant. No data package has been live (each one depleted, expired, removed, or failed) for the expiry window. Not terminal: a completed top-up returns the eSIM to active, and release remains available. Balances and the installed profile are untouched.
  • failed: provisioning failed; any charge on the owning order is credited back automatically, reported by that order. Terminal.

Possible values: provisioning, ready, activating, active, suspending, suspended, resuming, releasing, released, expired, failed

mode
string
required

Whether a purchase or eSIM is live or simulated. The mode is fixed when the order is created; the resulting eSIM retains it.

  • live: purchases service for use on a device and charges the wallet.
  • test: simulates a purchase without a charge or usable mobile service.

List responses can include both modes. Filter by mode when separating test activity from live purchases.

Possible values: live, test

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

Supported services for the eSIM. These values describe capabilities; package balances and current eSIM status determine whether service can be used now. Optional phone service can remain unknown until a number is assigned. Data packages do not establish call or SMS allowances.

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

Device-side installation state of the eSIM profile.

Show child attributes
installation.state
string
required

pending: not yet downloaded by a device; downloaded: downloaded but not installed; installed: installed on the device; removed: deleted from the device; whether the profile can be installed again depends on the carrier profile, so treat removal as final; error: download or installation failed, see error_reason. Open enum: installation state is reported by the device, so additional states may be added over time. Treat an unrecognized value as a future state, not an error.

Possible values (may grow over time): pending, downloaded, installed, removed, error

installation.updated_at
nullable string

When the installation state last changed. Null before the first device interaction.

installation.error_reason
nullable string

Human-readable reason installation failed, for example an ineligible device or an exhausted download limit. Null unless state is error.

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
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.

Possible values: available, unavailable

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
