I don't remeber if anyone has mentioned about this earlier :unsure:
About an hour ago, I noticed accidentally a Google Ad on the top of this forum
which lead me to
http://www.call28.com.
It's another Manx SIM.
My first impression are:
1) Rather expensive. Especially you won't like rates to mobile phones in some tiny European country :P
2) It seems there's no free incoming calls (calculator doesn't show the rates for incoming calls!) although the "basic" rate seems to be rather low (example table shows that it's 0.03 GBP for Australia, France, Germany and Italy)
3) I didn't find info about debiting, SMS and data rates
