I am about to go to Egypt. How can EE use mobile networks on Egyptian soil?

Using your phone abroad is called roaming, and the process differs between pay-monthly and PAYG

Regardless of any billing add-on, your ability to get coverage abroad (which calls, texts & mobile data rely on) is dependent on roaming being activated - which allows your phone to connect to foreign networks. The costs are set out at https://ee.co.uk/help/mobile/roaming/roaming-costs 

On PAYG, this is auto-enabled once your phone is used in the UK first.
On pay-monthly, this needs to be enabled manually - usually by texting ROAMING to 150 before leaving the UK.

@850010204 it is expensive to use data in Egypt, but you should be able to use wifi there. I was in Egypt and used wifi in the hotel, although it was only possible in the reception area, but that will depend where you are staying, as to whether it is available in your room. I also went on the Nile cruise and there was wifi available on the boat. Restaurants may have it and leisure areas. I just paid a fee with EE to be able to make calls, that was a monthly subscription. You can check the link @bristolian  has given you for the pricing.
