I bought my Swisscom EasyRoam SIM and subsequent airtime from GSM profi, a German service provider. They have provided me with good service and their prices are cheaper than the US providers. Although I can't fully understand the brochure they sent, they have announced that Swisscom has decided to eliminate EasyRoam as of Dec 31 of this year. Since I am not fluent in German, I can't read the fine print.

They will offer Kiwi Mobilux in its place (www.kiwi-prepaid.com). This looks to be a much better deal than EasyRoam as it will cost 0.89 Euros/min to place calls in most of Europe and the US to any of the zone 1 countries (Acores, Andorra, Belgium, Danmark, Germany, Spain, Finland, France, Ireland, Italy, Canada, Lichtenstein,
Zone 1 Madeira, Monaco, Norway, The Nederlands, Austria, Poland, Portugal, Sweden, Switzerland, USA (excl. Alaska and Hawaii), Vatican, UK ( incl. Channel Islands).
