perhaps you misunderstood the info...as far as I recall, getting a prepaid SIM by a foreigner requires lot of paperwork and a valid residence address, that if you are staying for few days or weeks is totally disproportionate, hence the best advice is to get it from a local contact in his name (perhaps the hotel in which you stay may arrange one). On the other way I saw the cost for an IDD call to EU to be extremely low, and that was a pleasant surprise.
