I searched but could not find answer to this.

I will be travelling from the U.S. to Egypt (Cairo, Aswan & Luxor). I have an unlocked quad-band phone. Can I get prepaid SIM card in Cairo? Is it available at the airport. Would it be crazy expensive at the airport and better to wait until we get to the city? Is it easily purchasable by tourist.

Any suggestions/recommendations? I foresee using my cell for maybe max of 30-60 mins (calling hotel, making a few price enquiries etc)

TIA.
