I'm betting that Tony is a person you only know online and that you have met him on an internet dating or social networking site and begun a romance with him. This has all the signs of a romance scam.
You NEVER have to pay any money to receive an award. That's the #1 sign of a fraud. Once you've truly won a contest the money is already yours, and you never have to pay a charge to get it. If there were any transfer fees involved, the contest would take it from his money, which they already have, and then hand him a check for the rest.
What he's doing is called the Stranded Traveler scam. He's fabricated an emergency which is designed to have YOU wire him some money via Western Union or MoneyGram, and to make you believe he'll have the wherewithal to pay you back when you finally meet. But you will never meet because this man doesn't really exist. He's a group of thieves hiding behind a fake profile and the picture of some other person.
The phone number he's given you is not a hotel number. It's a mobile phone, so even though the numerical exchange traces to Egypt, he can be reached at that number anywhere in the world he happens to really be.
He can get his VISA card replaced and FedExed to him overnight. If he's a Greek citizen, he can go to the Greek embassy in Cairo, where of course, they would have no problem understanding his accent, and they can help him access his funds at home. If he's a US citizen, he can go to the US embassy. However thick his accent, they can understand him, as I assume since he writes a fluent English to you, in the worst case scenario he can write it to them as well.
A reverse search of public records on a commercial background service shows that there is no such person named Tony Papadopolus who lives or has lived anywhere in the US. I looked it up and got similar results for Anthony Papadopolus.
Cease all contact with him. Do NOT send him money. Report him to the FBI at IC3.gov, which is their Internet Crime Complaint Center.
