People have no idea how much we have come to rely on cell phones for everything. My daughter had an accident (she's fine) and I got a call from the sheriff on his cell phone. I had already left work and heading toward my other daughter's dentist appt. 50 miles away. Had I not had a cell phone, I wouldn't been notified until about 5 hours after it happened. The ER also called to get authorization to treat. I just can't imagine...
There are just so many things - callbacks for job interviews, making appointments, getting calls from kids' schools, emergencies - that make cell phones such a useful tool.
250 minutes should be enough to use the cell phone for its intended purpose but not enough to just sit and text/talk all day.
