The service, which launched on October 6, 2009, provided a free mobile phone back-up solution by wirelessly synchronizing contacts, calendar appointments, tasks, text messages, browser favorites, photos, music, video and documents with a password-protected online portal where users could access and manage their information.

The service also enabled photo sharing and, in some markets, a set of features for dealing with a lost phone that were sold as a Premium Package requiring a one-time fee.

[1] Data (contacts, calendar entries, text messages, and photos) was moved to SkyDrive (which has since been rebranded as OneDrive).

Microsoft announced and launched the beta version of My Phone at Mobile World Congress[2] on February 16, 2009.

The Premium Package is available in the United States, Canada, Mexico, United Kingdom, Germany, France, Italy, Spain, Portugal, Denmark, Netherlands, Greece, Poland, Finland, Norway, Sweden, Brazil, Australia, Japan, Singapore and Taiwan.
