# 移动运营商流量差异

识别移动运营商用户（3G/4G）是一项复杂的功能。

我们使用我们自己的和第三方的 IP 地址数据库来识别运营商，这需要持续维护。根据您使用的工具，以及该工具识别用户的方式（IP 地址、ISP 名称……），您可能会看到差异。因此，我们无法保证此识别的准确性。

如果您需要 100% 的准确性，我们建议您改用您自己的 IP 地址范围，并使用 [IP 地址范围定向](/advertisers/zh/guang-gao-xi-lie/chuang-jian-guang-gao-xi-lie/create-campaign-step3.md#ip-ranges) 选项，该选项位于创建/编辑您的广告系列时第 6 步“高级设置”中。

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.exoclick.com/advertisers/zh/guang-gao-zhu-chang-jian-wen-ti/chang-jian-wen-ti/yi-dong-yun-ying-shang-liu-liang-cha-yi.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
