how do you use App Store when overseas

I have the same problem, my iPhone is registered in the US and I can't open the app store in Europe, it just not opening it saying that "It can not be open" I also get misleading messages like " You must connect to a wi-fi network or cellular data" despite I have connected to the Wi-Fi and cell data as I am able to open websites in the browser.

After speaking to the guys in the Apple store in London they confirmed that the app store in foreign phones sometimes opens in UK but most of the time not.

In the modern world, if Apple hasn't noticed that, we need to rent a car or buy a train ticket in the app as there is no option to buy it physically and obviously none of us have credit cards in all countries we visit. If I would know that this is the Apple policy to prevent me from using the app store abroad I would never buy this phone for $ 1300 to face such silly and disappointing issues.

you cannot just change Apple ID to the country where you are without having bank card of that country, which is literary impossible to have bank account in every country you traveling to

You may only download content from the country's store where your Apple ID is located. You may not download apps, free or paid, from any other country's App Store. That has always been Apple's policy since the first day of the App Store beta program 10 years ago.

In order to change the country where your Apple ID is authorized, you must supply a local payment method, such as a credit card issued from a bank in that country with a verifiable billing address in that country.

M1 Mac mini, macOS 12.4; Watch, series 5 GPS/cellular, watchOS 8.6; iPad Pro 2nd Gen, iPadOS 15.5; iPhone 12 Pro, iOS 15.5; TV 4th Gen, tvOS 15.5; HomePods, audioOS 15.5 and Airport Express w/ Airplay 2

Actually, it is because of content ownership, copyright.

Developers decide which counties in which their apps are available. Average small developers usually don't offer worldwide tech support. They don't want the expense of having to provide tech support to folks who download their app in one country and then take it home to a different country in which the developer did not intend for their app to exist!

Users don't get to dictate to the app owners how their app should be distributed.

Current options are to switch your Apple ID to the country or region you are in, or wipe and reload the iPhone and use a second Apple ID for the country or region you are in.

Media and content and app providers and financial providers and telcom device requirements are generally not global.

and the most interesting part of the story is that I can open the app store abroad on my iPhone 7 plus but not in new 13 Pro Max. So if travel abroad often stick to the older versions :))

Actually, you can. A local bank card is not the only form of payment that you can use. Use your foreign credit card to buy a small local Apple gift card and redeem that as your local payment method.
