SIM cards for mobile phones can be purchased from authorized distributors (Vodafone, Wind, and OTE-Cosmotone), or in shops that sell mobile phone equipment. You need to have your passport with you at the moment of purchase (there is no possibility of buying it without registration).
A safe place to buy a SIM card this summer 2022 is the GearCube Shop in Neos Marmaras, at this address:
GearCube – Neos Marmaras
Kiriakidou, Neos Marmaras 630 81, Greece
+302375071217

Another solution is Arkians mobile centers in Nikiti. This shop is on the main road to the beach – right on the main traffic light in Nikiti, towards the beach, and after around 50 meters you will see Arkias Mobile shop on the left. The address is:
Arkians mobile centers – Nikiti
Neakitou 31, Nikiti 630 88, Greece

In official offices in Thessaloniki
In Thessaloniki, we went to the Cosmotone official store and asked how much a new SIM card with unlimited internet costs for a month. There, the friendly operators told us that the purchase can only be made with a passport, for registration, and that the package with unlimited internet for a month costs 12e. When inserting the card into the device, it is necessary to turn on the mobile data option again and set it to the 5G network, for the fastest internet connection. On this card, you also get a small amount of credit for local calls, which you can easily top up at almost any store and store later if you need it. Topping up is done with a simple SMS, which you will receive from the seller. The procedure is easy and fast…
Also, if you arrive in Sithonia by car or bus, you can buy a Vodafone SIM card with your passport at the first ECO gas station after the Evzoni border crossing.
It would be a good idea to buy a SIM card before you arrive in Sithonia because it’s much easier to do it in bigger cities in Greece, such as Thessaloniki, etc.
