Two questions about Belgrade, Serbia
1) Do they exchange Norwegian, or Swedish kroner at the currency shops in central Belgrade, or is just euros, and dollars they're after?
2) What's a good "SIM card pack" to purchase for calling local mobiles in Serbia, Montenegro, and Croatia. It would be nice to keep the same number as I travel throughout the Balkans this summer. In Norway, I found Chess startpacke which was great because it cost only 100kroner, and included the same amount of airtime credit. I use it sproadically, and 3 months later (in Sweden, and Denmark) I still haven't needed to top up. I guess what I'm asking for is a similar setup for the Balkans.
Thanks.
