Does model No. MYN23AH/A sold in middle east supports e-sim

Dual SIM models come from China, Hong Kong, or Macau. They do not support eSIMs. They are not meant to be sold in the Middle East. If it is being sold there, it is a grey market phone. It has already been purchased which means the warranty is already being used up and you won't get a warranty for it outside of those 3 countries I mentioned.

It is a used phone, do not buy it, this is a bad deal.

All iPhones that offer dual nano-sim are either CH/A, MO/A or ZA/A model. Facetime audio is disabled on all CH models, while all ZA models function like every other iPhone. I am not sure about MO. Never owned one. As for your AH model it offers one nano-sim and one e-sim with all features intact. It is offered in Kuwait and Bahrain and now in Oman apparently. All other Arab market models are offered under the AE tag. In any case, the phone is being sold in its intended region, and as such the other comment's suggestion is incorrect and baseless. Hope this helps.
