Default Cant up date and Cant use Hotspot

I am currently living in Egypt and my dad got me the HTC one m8 as a present from the states. Its the Verizon unlocked version but the problem is I cant seem to update it because it keeps asking for the CDMA mode only"!!! sooo annoying and the type of service I'm using here is GSM/UMTS. Does anyone have a solution for this problem?
another problem is I cant use hotspot because I dont have Verizon Sim :S:S any solution for that too ?
