Necessity is the mother of inventions they say, and in this case, it provides a good service at reasonable cost. I understand the schools ban, and I understand the kids wanting their phone close. This solves both problems.

A ban on cellphones in schools is ringing up sales for two entrepreneurial New Yorkers.

Vernon Alcoser and his partner, a former school principal, offer a cellphone drop-off for New York City students unwilling to leave their mobile phones at home. For a dollar a day, they can store their phones at one of the bright blue trucks parked outside of their schools.

“This is so perfect,” said Osiris Cabrera, 16, a ninth-grader at a school in Manhattan. “The school won’t accept phones and you can’t leave the phone in your house. You need to get in contact with your family members or just in case of any emergency.”
