why i cant download any app and it always says payment method even the was free

Hi faiqaqmal95,

Welcome to the Apple Support Communities!

I understand that you are unable to download free apps from the App Store without being prompted to enter a form of payment. This situation can arise for a few different reasons.

The first step I would like you to complete is try and select None for your form of payment. The attached article below explains how to do this on your iOS device or in iTunes on your computer.

If None is not an option, the next attached article should help you isolate further depending on your situation and help you resolve the issue.
