App-only bonus offers只能在 App 领取的赠金

Seven of the 19 offers we read can only be claimed in the operator’s app, often an APK installed outside the app stores. The terms on the website and inside the app are not always the same.我们读过的 19 份优惠里，有 7 份只能在运营商的 App 里领取，常常是应用商店以外安装的 APK。网站上的条款和 App 里的条款不一定一致。

Before installing安装之前

• Read the in-app terms as well as the website terms.网站条款和 App 内条款都要读。
• Installing an APK means allowing apps from unknown sources; turn the setting off again afterwards.安装 APK 需要允许未知来源；装完后把设置关回去。
• Check that the app domain matches the website.确认 App 的域名和网站一致。
