Z5 Compact E5803 country compatibility

[ArgonHTA]

In dire need of help.
Recently, when trying to purchase an Xperia Z5 Compact phone through EBAY, I have come across both the E5803 model and the E5823 model. As far as I've seen they should both work fine in Israel where I live.
However, after completing the purchase for the E5803 model I was contacted by the seller, who claimed that this model will not work in Europe (Israel included) and not in North America either.
Could this be possible? Do I really need the E5823 model or will the E5803 work fine in Israel?

Thank you in advance to all who help.

E5823 work perfect in Israel and USA and as far as I knew all over the world, E5803 is for Europe .
