Ah- ok. I have a couple of UK SIM's for which I get free incoming calls (other person pays- their problem!) and all I have to do is make sure the number is called every 6 months. It's the ne plus ultra for those of us who don't need to make calls from the mobile for more than several hundred minutes a month.
Yes, that's not bad. The only European country I've found that has low mobile rates is Cyprus (South.) Until recently, it was a monopoly, so it's interesting it was so cheap. (I would have thought the small area and high population would make a difference there.)
