# @ohos.telephony.sim (SIM Management) (System API)

The **sim** module provides basic SIM card management functions. You can obtain the name, number, ISO country code, home PLMN ID, service provider name, SIM card status, type, installation status, activation status, and lock status of the SIM card in the specified slot. Besides, you can set the name, number, and lock status of the SIM card, activate or deactivate the SIM card, and change the PIN or unlock the PIN or PUK of the SIM card.

>**NOTE**
>
>The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.
> This topic describes only system APIs provided by the module. For details about its public APIs, see [@ohos.telephony.sim (SIM Management)](js-apis-sim.md).

## sim.delIccDiallingNumbers<sup>8+</sup>

delIccDiallingNumbers\(slotId: number, type: ContactType, diallingNumbers: DiallingNumbersInfo, callback: AsyncCallback\<void\>\): void

Deletes contact numbers from the SIM card in the specified slot. This API uses an asynchronous callback to return the result.

>**NOTE**
>
>A cache mechanism is available for SIM card contacts. When a contact is added, deleted, or modified, a SIM card contact cache is maintained based on the corresponding card slot ID and contact type. Therefore, when calling **sim.queryIccDiallingNumbers** to query contact numbers, you must pass the card slot ID and contact type to generate a a SIM card contact cache. If no cache is generated, the attempt to call the **sim.addIccDiallingNumbers**, **sim.delIccDiallingNumbers**, or **sim.updateIccDiallingNumbers** API will fail.
