Cricket Wirless and Samsung Telecommunications America (Samsung Mobile) unveiled the worlds largest working cell phone on Wednesday, March 11 in the Pioneer Court in downtown Chicago. The phone is a working replica of a Samsung Messager phone. The phone is approximately 15 feet long, 13 feet high, and 3 feet deep. Cricket invites all Chicagoans to make unlimited, free phone calls and texts on the life-size Samsung Messager through March 15. A Guinness World Records representative was on hand to certify the record-breaking phone. We are excited to recognize the worlds largest working cell phone from Cricket and Samsung Mobile as a new Guinness World Record, said Danny Girton, Jr., Guinness World Records adjudication executive. As this was a successful first record attempt, it is a tremendous accomplishment and we are delighted to welcome them into the Guinness World Records family.
