Cricket and Samsung Telecommunications of America (Samsung Mobile) are displaying the world’s largest working cell phone today in Pioneer Court in downtown Chicago. The largest working cell phone in the world is a working replica of a Samsung Messenger phone. The biggest wireless handset is approximately 15 feet long, 13 feet high and 3 feet deep. Cricket invited Chicagoans to visit Pioneer Court and make unlimited free phone calls and text messages on the life-size Samsung Messager through March 15. A Guinness World Records representative will be on hand to certify the record-breaking phone for the record.
