I am going to be in Greece for 22 days in July/August and will be going to 3-4 Cyclades islands as well as spending some time on mainland Greece. It seems like the best provider, although a bit more expensive, is Cosmote. Between my finace and I we have an unlocked Iphone 8 and and unlocked Pixel 2 so I don't think we will have an issue with compatibility. I've done a lot of searching but I can't seem to find any updated pricing for prepaid sim talk, txt and data plans. I would definitely be looking for a 30 day package and would like a minimum of 2gb of data. We will be renting cars throughout our entire trip and most likely relying on google maps to get us around. Can anyone with recent experience in this field let me know how much I would be looking at spending for 30 days of talk and text (international back to Canada) as well as a minimum of 2gb of data.
