Probably not, majority of CE is 30 and over. Early to mid 2000 was not saturated with cells phone, and most of them were dumb phones.
Pay phones and TI-85's.Funnily enough my high school did have a pay phone when I was there but by the time my stepsister was in hs it was gone.
Internet wasnt even a thing let alone cell phones.
When I was in grade school cellphones were the size and weight of a brick and only millionaires could afford them.
I first saw a cell phone on The Fresh Prince. It was one of those bricks.My aunt had one in the '90s that looked like a regular cordless landline phone except it had an extra button to dial.
