Q: Buying from online Apple store of United Arab Emirates with an Egyptian Visa or Mastercard

To get answers to such questions you need to contact the store directly yourself

I don't know if it helps, but last year I used my credit card issued in Poland to reserve an iPhone for pick up in Apple Store in Berlin and had no problems whatsoever.

I am in Egypt right now and the store doesn't support international chat .

One way or another you will have to communicate with them directly yourself.  Nobody in these forums represents Apple or any store, we are just other users like you.

Good luck!
