Postpaid SIM cards
Postpaid SIM cards can be obtained from your service provider, an activation partner, or your IT department. Cisco is not responsible for SIM card activation.
You are not limited to using the SIM card included with your Cisco Cius. You can also use an existing or new SIM card which can be added to your existing service provider account.
Viewing Data Usage
You can view both pre and post-paid real-time AT&T account data usage using the pre-installed AT&T Communication Manager desktop widget, or by logging into your AT&T account online.
Figure 1 provides an example of the widget displaying real-time data usage for a prepaid account.

Adding Cisco Cius 4G Devices
You can add a Cisco Cius device individually to the Cisco Unified Communications Manager database by using Cisco Unified Communications Manager Administration. To add the Cisco Cius 4G device, see Preparing to Install Cisco Cius on Your Network.
Cisco Cius 4G uses VPN to connect to your enterprise network and Cisco Unified Communications Manager. When transitioning from a 4G to Wi-Fi network during a call over VPN, the 4G connection is maintained until the call is ended.
When transitioning from a Wi-Fi network, the call is dropped.
