We will be in Greece for about 10 days and would like to buy a domestic SIM. In looking at the available plans, it is very confusing. I need a plan that SMS, voice and data bundled. I can't seem to find a bundle that has all three. There are voice + internet and just SMS. Do I need to buy a voice + data package and then add a SMS package? I estimate we will need say 100 SMS, 100 minutes and 1 Gig of data (mostly for google maps route navigation). I am not stuck to Cosmote and open to any provider. Has anyone had any experience using google maps on your phones and does it work pretty well? Would you recommend renting a GPS unit instead?
Is there a Germanos store at the ATH airport selling Cosmote SIMs? I see conflicting information doing a google search.
We will be traveling to France a month later. Do the new Euro roaming laws mean I can use the same SIM? How does it impact costs?
