Do you have free calls back to Switzerland and other countries when roaming in Germany (or any of the other countries I listed)? I am in Germany almost every second day and need to make calls to the US pretty much daily.

With my usage pattern this is definitely the cheapest plan, I did a lot of research.

Spusu is absolutely a great value if you mostly need your phone for data when abroad though, but in my case calls are still a big deal.
