June 7, 2010 - A Swiss company called Starhome GmbH filed a patent infringement lawsuit against AT&T and T-Mobile in U.S. District Court in Delaware on May 25, alleging that the companies infringe Starhome's patents related to easy access to voice mail when the mobile phone service subscriber is abroad.

Besides AT&T Mobility LLC of Atlanta and T-Mobile USA of Bellevue, Washington, which is the U.S. subsidiary of Germany's Deutsche Telekom AG, a third company - Roamware Inc. of San Jose, California - was named in the lawsuit.

Starhome's patents cover a method of accessing voicemail and other mobile services with the same short PIN codes the user traveling abroad uses in their home country, without the need to enter long international calling codes.
