Approximately 88% of U.S. adults own some sort of cell phone and 55% of these adult cell phone owners go online using their phones. People in this segment are called “cell internet users” and 31% of these cell internet users mostly go online using their cell phone rather than other devices like a desktop or laptop. This breaks down to about 17% of all adult cell phone owners being “cell internet users” who mainly surf the internet using their cell phones rather than other electronic devices.
There is a continued rise in mobile internet usage. People are gradually doing a lot more of their surfing on their phone because of the convenience factor.

There is also a part of the cell internet user segment whose only method of internet access is via their cell phones.
