Changing SIM Cards

Subscriber Identity Module (SIM) cards are used to identify and authorize subscribers on mobile devices, such as cell phones or tablet computers. The SIM Number is a unique serial number used to identify each SIM card.

Businesses generally have many SIM cards on hand, and the Change SIM view allows a subscriber to associate the SIM card with the mobile device. The business swaps the physical SIM card, and you use Telco Subscription Management in Open UI to associate this device with the serial number of the SIM card.

Businesses might want to swap SIM cards for the following reasons:

• An employee's phone is lost or stolen.
• An employee has upgraded service, and the SIM card is no longer working.
• An employee has gotten a new phone that needs a different size SIM.
• An employee's SIM does not work for some other reason.

A bar is a service that restricts a phone's usage. For example, to avoid additional charges when you travel outside your wireless service network, you can add the roaming bar option, which prevents you from using the phone when it is in roaming mode. If you lose your phone, or if your phone is stolen, then you can call the wireless service provider to add the stolen bar option, which prevents unauthorized use of your phone and stops any charges being added to your account.

A user cannot change SIM cards on a service that has a stolen bar enabled. This validation, and similar rules, can be configured by modifying the underlying workflows. For more information, see Workflow Reference for Telco Subscription Management in Open UI.

To change SIM cards

1. From the Action Launchpad menu of the Customer Dashboard, select Change SIM.
2. In the list of mobile phone numbers for that customer, find the number whose SIM you want to change, and click the plus (+) icon next to it to display information about the current SIM card number and bar services.
3. Click the Select button next to a service to add it to the right pane.
4. When you click the Select button, the application checks for bars and, if necessary, it might display one of the messages shown in the following table.

   Error or Warning Message	Action

   Warning! There is a roaming bar for the selected service. Note that the roaming bar will be migrated to the new SIM#.	No action is required. This warning message informs you that the roaming bar is included. The selected service is added.

5. In the right pane, which has the heading Enter New SIM Card and Due Date for the Selected Service, enter the necessary information about the new SIM card or cards that you want to associate with this phone number. Some fields are described in the following table.
