Sim Resource


(information)

Info

To avoid ambiguity throughout this page, Sim (initial cap) refers to the Sim API resource. SIM (all caps) refers to the physical Subscriber Identity Module (that is, a SIM card) associated with a Sim resource.

A Sim instance represents a single physical Super SIM:

https://supersim.twilio.com/v1/Sims

A Sim instance can be referenced in the API either by its unique sid or a user-defined unique_name:

1
https://supersim.twilio.com/v1/Sims/{sid}
2
https://supersim.twilio.com/v1/Sims/{uniqueName}

Before a Super SIM can begin using data or sending/receiving SMS via Commands, the corresponding Sim instance must be assigned to a Fleet and activated.

The table below describes the available status values of a Sim instance:

StatusDescription
newThe SIM has never been enabled and is waiting to be activated so that it can connect to the network. A Sim resource can exist in new status indefinitely at no charge, but once it is transitioned to ready or active, it cannot be returned to new.
readyThe SIM can connect to the network and is capable of consuming network resources in accordance with its Fleet, but no monthly subscription fee will be charged . A Sim resource's status can only be updated to ready if it is currently new.Once the SIM has consumed 250KB of data, five SMS Commands have been sent to or received from the SIM, or three months have passed, the Sim resource's status will automatically transition to active.Use ready to enable and test your connectivity before devices are sent to customers or deployed into the field without incurring monthly fees.
activeThe SIM can connect to the network and is capable of consuming network resources in accordance with its Fleet.
inactiveThe SIM is blocked from connecting to the network.
scheduledThe update is queued and will be processed when the network operator is ready. The Sim resource's status will automatically transition to the requested status when the update operation is completed.

Add a Super SIM to your Account

POST https://supersim.twilio.com/v1/Sims

(warning)

Warning

All Super SIMs purchased through Console(link takes you to an external page) arrive pre-registered to the Twilio account which placed the order. To receive an unregistered Super SIM that is eligible to be added to your Account, you will have received the SIM either at an in-person event, such as a developer conference, or from an independent partner as part of their solution.

If you are interested in ordering unregistered SIMs for your use case, please contact sales-wireless@twilio.com to speak with an IoT Sales Specialist.

If you have a Super SIM that has not yet been registered to a Twilio Account, you can add it to your Account by providing the SIM's ICCID and the registration code. On a plastic multi-size SIM card, these two values are printed on the card. For an embedded SIM (MFF2), if you have a registrable SIM, you will need to obtain this information either from your vendor or from Twilio.

Property nameTypeRequiredPIIDescription
Sidstringrequired

The SID of the Sim resource to update.

Encoding type:application/x-www-form-urlencoded
SchemaExample
Property nameTypeRequiredDescriptionChild properties
UniqueNamestring

Optional

An application-defined string that uniquely identifies the resource. It can be used in place of the resource's sid in the URL to address the resource.


Statusenum<string>

Optional

The new status of the resource. Can be: ready, active, or inactive. See the Super SIM Status Values for more info.

Possible values:
readyactiveinactive

Fleetstring

Optional

The SID or unique name of the Fleet to which the SIM resource should be assigned.


CallbackUrlstring<uri>

Optional

The URL we should call using the callback_method after an asynchronous update has finished.


CallbackMethodenum<http-method>

Optional

The HTTP method we should use to call callback_url. Can be: GET or POST and the default is POST.

Possible values:
GETPOST

AccountSidstring

Optional

The SID of the Account to which the Sim resource should belong. The Account SID can only be that of the requesting Account or that of a Subaccount of the requesting Account. Only valid when the Sim resource's status is new.


Some Sim resource updates will be completed asynchronously. To receive a notification when a Sim resource has finished updating, provide a callback_url and a callback_method with your initial HTTP request.

When an update is handled asynchronously, the Sim resource will undergo multiple updates:

  • First, the Sim resource's status will be set to scheduled as the update is placed in a queue.
  • Finally, the Sim resource's status will transition to the final state.

If a Sim resource's Fleet is changed as part of an asynchronous update, the existing value of the fleet_sid property will be returned when the update request is accepted. When the update completes, the new value will be shown on the Sim resource.

(information)

Info

In the scenarios below, "activating" means updating the Sim resource's status to a value that will allow the Super SIM to use cellular network resources: either ready or active. Please refer to Status values for descriptions of each status.

The following update scenarios will be handled asynchronously:


Activating a Sim resource

activating-a-sim-resource page anchor

When a Sim resource's status is updated from new to ready or active.


Deactivating a Sim resource

deactivating-a-sim-resource page anchor

When a Sim resource's status is updated from active to inactive.


Reactivating a Sim resource

reactivating-a-sim-resource page anchor

When a Sim resource's status is updated from inactive to active.


Changing an activated Sim resource's Fleet

changing-an-activated-sim-resources-fleet page anchor

When a Sim resource is already ready or active and its Fleet is updated. When the update request is accepted, the Sim resource's status will change to scheduled. The Sim resource's fleet_sid property will be unchanged at this point. If the update succeeds, the Sim resource's status returns to ready or active and the Sim resource's fleet_sid property now returns the new Fleet resource's SID.


If you provided a value for the callback_url parameter in your update request, the asynchronous request made to that URL will contain the following parameters.

SimSidThe unique SID of the Sim resource that this callback is in reference to.
SimUniqueNameThe Sim resource's unique_name if it has one.
SimStatusA string representing the Sim resource's status after the update completed.
AccountSidThe unique SID of the Account that the Sim resource belongs to.

If the callback_method was set to POST or not provided, the callback parameters will be delivered as HTML form parameters. If the callback_method was set to GET, the callback parameters will be delivered as a query string.

Move Super SIMs between Subaccounts

move-super-sims-between-subaccounts page anchor

If you are using Subaccounts, you can transfer new Super SIMs between your accounts.

While using the primary Account's credentials, use the account_sid parameter to provide the Account SID of the Account you wish to own that Super SIM. Super SIMs can be moved between Accounts the following ways:

  • From the primary Account to a Subaccount.
  • From a Subaccount to the primary Account.
  • From a subaccount to another Subaccount.
(warning)

Warning

If the Super SIM you are moving is assigned to a Fleet, you must also pass the sid or unique_name of a Fleet resource that belongs to the new Account, or null, in the fleet parameter of your Update request.

When you move a non-new SIM to a new Account, you will not get any results from the Sim BillingPeriod subresource until the current active Billing Period expires and a new one is created that will belong to the new Account, even if you reactivate the SIM. If the Billing Period on the previous Account has already expired (e.g. the SIM was left in inactive for a couple of months and is now going to be used again on the new Account), then a new Billing Period will be created on the new Account when the SIM is reactivated. Not knowing the Sim resource's Billing Period start and end dates will prevent you from being able to accurately determine how much of the SIM's data limit you've utilized unless you have saved this information outside of Twilio.

When you move a SIM to a new Account, the counter tracking data usage towards the SIM's data limit does not reset. This usage counter is tied to the SIM's Billing Period. If the SIM's status was active within the last 30 days, it's most recent active billing period may not have expired yet. Any usage incurred when the SIM belonged to the previous Account will still be counted towards the data limit inherited from the SIM's current Fleet. However, you will not see that usage on the new Account as the SIM's Usage Records do not transfer to the new Account.

Let's look at an example. If you have a SIM that belongs to Account A and its Billing Periods start/end on the 2nd of the month because that's when it was originally activated a few months ago and you use 5 MB between the 2nd and the 10th of the month. On the 10th you want to move it to Account B, a subaccount of Account A. You update the SIM's status to inactive and then move it to Account B. You assign it to a Fleet with a 15 MB data limit and reactivate the SIM and begin using it. Because the SIM was reactivated before it's current Billing Period expired, that existing Billing Period is re-used and it will continue to start/end on the 2nd of the month. However, because the same Billing Period is used and your data usage towards the data limit is linked to the Billing Period, the 5 MB's you used earlier in Billing Period (between the 2nd and the 10th) count towards the 15 MB data limit.

Settings Updates History

settings-updates-history page anchor

If you move a SIM between Accounts, the entire history of Settings Updates follows the SIM and will be returned from the SettingsUpdates resource when querying it with the new Account's credentials. You will no longer be able to view the Settings Updates for the SIM in the previous Account's results when querying the Settings Updates resource.
