搭载 Android 9 的设备可以识别订阅运营商信息,以提供相应 ID 和运营商名称。Android 维护着一个运营商 ID 数据库,该数据库采用每个运营商对应其唯一运营商 ID 的匹配规则。AOSP 的 carrier_list.textpb 文件中包含运营商 ID 数据库的内容。统一的数据库有助于最大限度地减少需要识别运营商的应用内的重复逻辑,并限制暴露可用于识别运营商的属性。
为了更准确地识别更多运营商,Android 支持带外运营商 ID 表更新。每个更新版本都会有一个版本号,并会发布到 AOSP。

Android maintains a carrier ID database, with\nmatching rules for each carrier and its unique carrier ID. AOSP includes the\ncontent of the carrier ID database, in the file\n[`carrier_list.textpb`](https://android.googlesource.com/platform/packages/providers/TelephonyProvider/+/android16-release/assets/latest_carrier_id/carrier_list.textpb).\nThe unified database minimizes duplicate logic in apps that need to identify\ncarriers and limits the exposure of carrier-identifying attributes.\n\nTo improve the coverage and accuracy of carrier identification, Android supports\nout-of-band and carrier ID table updates. Each update comes with a version\nnumber and is published to AOSP.\n\nImplementation\n--------------\n\nUsers who want to implement out-of-band updates can download the\n[`carrier_list.pb`](https://android.googlesource.com/platform/packages/providers/TelephonyProvider/+/android16-release/assets/latest_carrier_id/carrier_list.pb)\nbinary from AOSP. To view the readable format of the table, see\n[`carrier_list.textpb`](https://android.googlesource.com/platform/packages/providers/TelephonyProvider/+/android16-release/assets/latest_carrier_id/carrier_list.textpb).\n\nPlace the carrier ID table in the `/data/misc/carrierid/` data partition of the\ndevice. If the carrier ID table is newer than the existing version, the device\npersists the table to the\n[carrier ID database class](https://developer.android.com/reference/android/provider/Telephony.CarrierId).\nThe most recent information from the carrier ID database is picked up by the\npublic methods\n[`getSimCarrierId()`](https://developer.android.com/reference/android/telephony/TelephonyManager#getSimCarrierId())\nand\n[`getSimCarrierIdName()`](https://developer.android.com/reference/android/telephony/TelephonyManager#getSimCarrierIdName()).\n\nAdd carrier ID information to the database\n------------------------------------------\n\nTo add or update a carrier ID to the database, submit a request using the\n[Carrier identification information form](https://docs.google.com/forms/d/1KjwTaExKRjkE9tbR9yavBrGzwvuz1dNku2Ae_7GrdUQ/viewform?edit_requested=true).\n\nYour request is reviewed and if approved, the change is pushed to the AOSP code\nbase at\n[`carrier_list.pb`](https://android.googlesource.com/platform/packages/providers/TelephonyProvider/+/android16-release/assets/latest_carrier_id/carrier_list.pb).\nYou can then copy the updated list and incorporate it into your customized\nbuild.\n\nIntegrate carrier IDs with CarrierConfig\n----------------------------------------\n\nStarting from Android 10,\n[carrier configuration](/docs/core/connect/carrier) supports\nusing carrier IDs as keys to fetch carrier-specific configurations from\n[`CarrierService`](https://developer.android.com/reference/android/service/carrier/CarrierService).\n\nIntegrating carrier IDs with `CarrierConfig` has the following advantages:\n\n- Consolidates all MCC/MNC pairs for each carrier into a single location removing duplicate or inconsistent data.\n- Creates a canonical identifier for each carrier and removes ambiguity.\n- Allows mobile virtual network operators (MVNOs) to be identified with individual IDs instead of having configurations as part of a mobile network operator (MNO).\n\n### Migrate configuration data to carrier IDs\n\nTo migrate configuration data from MCC/MNC pairs to carrier IDs, follow\nthese steps:\n\n1. Group the `carrier_config_mccmnc.xml` files from a single carrier together.\n Use\n [`carrier_list.textpb`](https://android.googlesource.com/platform/packages/providers/TelephonyProvider/+/android16-release/assets/latest_carrier_id/carrier_list.textpb)\n as a reference to map the MCC, MNC, and MVNO information to a particular\n carrier.\n\n2. Merge the configurations into a single file.\n\n3. (Optional) Inherit data from MNOs. MVNOs inherit configurations from\n MNOs in the legacy `carrier_config_mccmnc.xml` file. Because carrier IDs\n allow all carriers including MVNOs to have a dedicated config file, it's\n recommended to include MNO data during migration.\n\n4. If the configuration for an MVNO carrier ID doesn't exist, fetch the\n configuration from its MNO carrier ID using\n [`getCarrierIdFromSimMccMnc`](https://developer.android.com/reference/android/telephony/TelephonyManager#getCarrierIdFromSimMccMnc()).\n\n5. Rename the new file as\n `carrier_config_carrierid_`\u003cvar translate=\"no\"\u003ecarrierid\u003c/var\u003e`_`\u003cvar translate=\"no\"\u003ecarriername\u003c/var\u003e`.xml`\n where \u003cvar translate=\"no\"\u003ecarrierid\u003c/var\u003e must correspond to a `canonical_id` and\n \u003cvar translate=\"no\"\u003ecarriername\u003c/var\u003e should correspond to a `carrier_name` in\n [`carrier_list.textpb`](https://android.googlesource.com/platform/packages/providers/TelephonyProvider/+/android16-release/assets/latest_carrier_id/carrier_list.textpb)\n\n| **Note:** If a `carrier_config_mccmnc` file doesn't have a matching carrier ID, submit a request to add a carrier ID by following the steps in [Adding carrier ID information to the database](#adding_carrier_id_information_to_the_database)."]]
