Answer: Laggard
Explanation:
The meaning of Laggard is that of a person who is very slow or who is far behind. This word can be adapted to what George has said about not having a cell phone these days. Today we live in the age of communication and information, where all people have a device that allows them to communicate with others, such as a telephone or computer. George, not having a phone, will make him look like someone who is not at the forefront of what today's society expresses, which is about constant and rapid communication.
