All European SIMs have free incoming calls in the country of origin (and the cost is capped when roaming within the EU to about 20 cents/min, depending on the local VAT rate). As mentioned above, several German SIMs have 9 cent/min calls to the US. Solomo is probably the best deal overall, but only available online. Fonic is also 9 cents, and widely available in drugstores and supermarkets. Both offer 24 cent/MB standard data rate.
