Travelling to France, Italy, Greece and Turkey, need sim card advice (please)

[sugar150]

Hi everyone,

I'm planing on travelling to France, Italy, Greece and Turkey this summer. I have been trying to figure out what my best option is for a sim card to use in the countries I will be visiting.

I will be spending most of my time in France and Italy and only two weeks in Greece a Turkey (combined).

I currently have a quad-band phone that has been unlocked. I primarily plan on using the phone for emergencies, and to call some of the people I will be visiting in the countries I'm travelling to as well as back home to Canada. I don't plan on making a lot of calls, over the three month period, but I know my family and friends will be calling me.

In France i know there's SFR (owned by vodafone) and Orange
Italy: Wind or Vodafone and TIM (I don't want to deal with the hassle)
Greece: wind, Cosmote and vodafone
Turkey: Vodafone, avea and turkcell


So here are my questions:
1. Does anyone know if incoming calls to the above sim cards are free?
2. Is it better to just get a vodafone card and roam while in the other countries (I would be able to keep my phone number) or just buy a country specific card (can't keep old number)?
3. Is there a sim card that I could use in all those countries, where I would get free incoming calls, and a flat rate for outgoing and not be charged for roaming?
4. Are there restrictions for getting any of these sim cards like requiring a local address etc. ?
5. Can I order any of these online before I leave so I have it when I land?
6. If it's best to buy a sim card when in Europe does anyone know if I can buy sim cards in CDG airport in Paris?


I would really appreciate some help on this, I have been searching the internet for as much information as possible so that I'm well prepared when I arrive.

Thanks
