I can't change my region.I wanna get youtube app😞

Hi,

If the YouTube app isn’t available in App Store because of your Apple ID region, you can create a new Apple ID in a region where YouTube is available and then sign in with this one in App Store.

Please note sign in with another Apple ID in App Store will change the payment method, billing info, purchases made, iTunes Store region…etc

It however won’t affect the ‘main’ Apple ID associated to your device (photos, iCloud, backups…etc), only Apple Purchase Services.

Please note I advise you to don’t change the region of your current Apple ID
