Think long and hard and you, too, will remember a time when (gasp) cellphones didn't even exist.
Today, you'll be hard pressed not to see someone texting in line at the grocery store, playing "Clash of Clans" on the subway, or walking down the street while talking on their Bluetooth. Heck, you're probably reading this very article on your phone.
But T-Mobile CEO John Legere told CNBC on Thursday that people will soon own not just one, but several mobile devices.
"Everybody will have multiple devices. Most people have more than one cellphone ... a tablet, wearable devices," Legere said on "Squawk on the Street." He said the future of wireless growth will come from charging customers for multiple devices on the same plan.
Legere credited this shift in mobile trends to T-Mobile's stellar growth in the second quarter. The wireless provider on Thursday posted its first net profit in a year, raised its forecasts for subscriber growth and reported the most postpaid phone subscriber additions in the industry.
Last year T-Mobile turned around years of subscriber losses through campaigns that have eliminated contracts, restructured pricing plans and sparked price slashing across the industry.
T-Mobile added 1.5 million net customers in the second quarter and 102,000 net prepaid subscribers, compared to prepaid subscriber losses for the top four wireless carriers.
"There is a lot of activity happening between carriers. There is a possibility for a large switching pool. We had a 30 percent increase in gross ads year over year so this is a healthy, growing industry," he said.
