Y can’t we use it in Lebanon

Hi bader2009,

welcome to the Apple (user-to-user) Community.

We are all Apple users, like yourself, in this Community. We do not know why Apple does what it does.

Seems not all countries participate, and not all banks in all countries participate in Apple Pay:

Apple support's article:

Apple Pay participating banks in Africa, Europe and the Middle East – Apple Support

says:

"We're working with more banks to support Apple Pay. If you don't see your bank listed, check back soon.

Some cards from participating banks may not be supported in Apple Pay. Contact your bank for more information"

If you want, you can send feedback to those who work behind the scenes on Apple Pay. They likely won't reply, yet your feedback will reach those who could help make changes.

Online web-form for feedback:

Feedback - Apple Pay - Apple

All the best :-)
