App 在你所在的国家或地区不可用
这句话表示这支 App 不在你的 Apple ID 所属商店里销售。你仍可以打开有它的那个商店页面，查看评分和评论。
Store Switch 不会更改你的 Apple ID 国家或地区。它用来打开另一个 App Store，查看评分、评论和排行。购买、订阅和账户国家仍由你的 Apple ID 决定。
为什么 App Store 会这样显示
「此 App 在你所在的国家或地区不可用」跟的是 Apple ID 上的国家，不是「想浏览一下」这个愿望。开发者决定在哪些商店销售。手机人在另一个地方，本身并不会把账户放进那个国家的商店。
同一支 App 可以出现在日本排行里，却不在你的账户购买所用的商店中。两边的评分和评论是不同的页面。
去看实际上架了它的商店
- 先确定开发者在哪个商店销售。可以从 日本、英国、香港 看起，其余地区在 完整列表 里。
- 用现在的 Apple ID 保持登录，用 Store Switch 打开那个商店。
- 阅读那里的产品页、评分、评论和排行位置。
打开页面不会把这支 App 放进你的已购项目，也不会更改你的 Apple ID 国家。
要购买，是另一步
要付款购买，Apple ID 的国家必须是开发者有在销售的国家。那就是 Apple 的更改国家流程，余额、订阅和付款方式都在那一页。另一个账户层面的办法，是使用国家已经能买到它的 第二个 Apple ID。Store Switch 不会替你完成这两件事，也不会下载账户无权购买的副本。
如果只是要评论或排行
停在商店页面即可。你可以比较这支 App 在另一个国家的表现，账户、订阅和余额都不用动。
在手机上打开这个商店
Store Switch 可在 App Store 免费下载。选一个地区，打开那个商店，Apple ID 的国家留在原地。
相关指南
Store Switch does not change your Apple ID country. It opens another App Store so you can read ratings, reviews, and charts. Purchases, subscriptions, and the account country still follow your Apple ID.
Why the App Store says this
“This app is not available in your country or region” follows the country on your Apple ID, not a wish to browse. Developers choose which storefronts sell the app. A phone that is physically somewhere else does not, by itself, put the account into that country’s store.
The same app can be on the Japan chart and absent from the store your account buys from. Ratings and reviews on those two storefronts are different pages.
Look at the store that lists it
- Find a storefront where the developer actually sells it. Country guides such as Japan, the UK, and Hong Kong are starting points, and the full list covers the rest.
- Open that storefront with Store Switch, still signed in to your current Apple ID.
- Read the listing, ratings, reviews, and chart position there.
Opening the page does not put the app into your purchases, and it does not change your Apple ID country.
Buying it is a different step
To pay for an app, the Apple ID country has to be a country where that developer sells it. That is Apple’s country change, with the balance, subscription, and payment requirements on that page. A second Apple ID whose country already sells the app is the other account-level route. Store Switch does not complete either one, and it does not download a copy the account is not allowed to buy.
If you only needed the reviews or the chart
Stop at the storefront. You can compare how the app is doing in another country and leave the account, the subscriptions, and the balance alone.
Open the storefront on your iPhone
Store Switch is free on the App Store. Pick a region, open that store, and leave the Apple ID country where it is.
