Find EXACT app in App Store

I just got an AT&T SIM and was looking for an app to manage the account.

A search came up with myAT&T but when I try to search the App Store on the phone I get dozens of irrelevant apps, but NOT what I was looking for.

How can I find EXACT app in App Store

EDIT

I searched in Safari (on the phone with the AT&T SIM), and clicked the link in the answer, but the result says "This app is only available on the App Store for iOS devices"

I am in the US - connected to AT&T, running iOS 10.3.3 (the latest for the iPhone5C)

I can launch the App Store app, but there is no download link, and it states "This app is only available on the App Store for iOS devices".

On my iPad I get an error "The item you've requested is not currently available in the Australian Store" - so I guess my problem then becomes how to use the US Store.

Solution 1:

Here is the app you are looking for:

myAT&T

The trick is to look for name of the app publisher shown under the app name.

Number and value of ratings is another factor to look for to ascertain the authenticity of the app coming from the intended publisher.

It is also a good idea to visit the service providers website and follow the App Store link for the app to ensure you are downloading the intended app.
