Does " ipad air model A1475 " supports cellular network type CDMA?

Hello dear

could you please do a favor for me and tell me if my "Ipad air model A1475 " supports

cellular network type CDMA?

i am in the middle east, exactly in Yemen and my ipad seem to be a free, i mean i doesn't

belong to any carrier in a particular, because there is not logo of any carrier on it and no special

applications of them. i had it brand new as a gift from my employer company. i read in the web

that this model is global and support both GSM and CDMA. but when i installed nano UIM card of

" Yemen Mobile " which is a CDMA carrier in my country, the ipad shows message says " No Service "

at the upper left corner of the screen.

so could you please tell me ASAP what can i do to solve this problem?

THANK YOU VERY MUCH
