Should cell/mobile phones have their own area code numbers?

With the massive amount of cell phones and other related devices,

wouldn't it have been better if these devices had their own designated

area code numbers? Every so may years, certain areas all around

the country have to change their area codes because they run out

of phone numbers. Also, cell phone companies have been known

to buy thousands of phone numbers in blocks at a time, thus

depleting numbers even more for area residents, companies,

businesses,etc.
