I've just ordered Sunsim (German) online, paid with UK credit card, delivered to a German address "in the next days". Mind you, it's not urgent for me, and you could end up with two gambles on delivery time.

edit - it arrived Tuesday, from order on Friday

It has cheap calls in Germany and cheap roaming. In Germany I'll use a callthrough arrangement for int'l calls. Other callback and forwarding rates would probably be cheaper than for Liechtenstein nowadays.

In Switzerland, you might go for Swisscom and use a calling card. On the easy liberty tariff, calls to Swiss landlines are only charged for the first minute. There are a couple of recent threads about German SIMs; Blauworld would be the other choice, for simpler cheap international calls, but I don't know if it's in shops
