Can I use an Iphone 5 that I bought in Europe elsewhere?

So, I was planning to buy an Iphone 5 in Italy and use it in Egypt since I'm here for work reasons. Will it work? Will I be facing some problems in the future with this move?

Yes you can, but beware that your warranty is not valid in Egypt. Iphone warranty is not international.

It will work without any problems. You need to unlock it if you want to use it with local carriers.
An it is true, the warranty for Iphone 5 is ONLY good in the original country of purchase.

Usually the networks in European countries are same or similar, so it is ok for you to use the cell phone you bought in Italy in anywhere in Euroupe. But I'm not sure about the conditions in Egypt.
You will need to learn about the networks and the SIM card they use in Eygpt!
