City.Mobi

Also in the United States today, City.Mobi is celebrating the success of its new guide to New York.

City.Mobi offers the most comprehensive mobile travel guides available, with over 800 cities in 200 countries listed. Each is developed by the City.Mobi team to combine into a single global travel directory.

However, each city retains its own mobile identity via a dedicated domain. Already on offer are Brussels.Mobi, Paris.Mobi, Sanfrancisco.Mobi and Sydney.Mobi.

NYC.Mobi is the latest in this illustrious line up, offering click to call functionality – which means no scribbling down telephone numbers.

Most entries are also linked to websites where users can quickly access more detailed information if needed.

Other key features include information on accommodation, restaurants, attractions, entertainment, nightlife, shopping, and transport.

City.Mobi guides include user reviews and traveller utilities such as a translation guide, currency converter, news and local weather guide.
