6. Can I unsubscribe/ re-subscribe/ suspend my Digi AirSIM?

Yes, you can. You will need to walk into a Digi Store to unsubscribe or re-subscribe to a Digi AirSIM Number Share service. 

If you suspend your Digi Postpaid line voluntarily while being on a Digi AirSIM Number Share service, only the primary line (i.e the phone) will be temporarily suspended. The accompanying Digi AirSIM Number Share service will not be suspended. However, if you would like to suspend both your Digi Postpaid line and the Digi AirSIM Number Share service, please kindly call customer service.

Note: Should you choose to transfer ownership of your line to someone or convert it to a prepaid line, you will need to unsubscribe from the Digi AirSIM Number Share service before you can proceed.

7. What are other supplementary services supported by the AirSIM?

Call Forwarding Unconditional (primary), Call Waiting and Call Hold are all supported with Digi AirSIM Number Share.

8. How can I track my Digi AirSIM usage and charges?

Digi AirSIM Number Share will appear on your bill as a 'Secondary SIM'. Domestic voice and data are covered under the standard Digi AirSIM Number Share service based on your primary Digi Postpaid plan. However, if you make a call directly from your Apple Watch to an overseas number, the standard International Direct Dial charging rates will apply as per the country rate published here. Standard charges apply for usage of voice, SMS, and data as these are not included in the standard Digi AirSIM Number Share service.

9. Can I pick up a call on both of my devices?

With Digi AirSIM Number Share, you may attempt to pick up calls on either of your devices. However, the call will only get connected to one device. Therefore, when you accept a call on the phone, you cannot listen in on the conversation from the watch and vice versa. Additionally, a watch cannot end a conversation picked up on the phone and vice versa.
