I started using a cellphone about 12 years ago, and since then I have never been without a cellphone for a week. Well, when my cell phone broke and I took it to the repairman, I was without a cellphone for a day or two, however, I have not been without a cell[phone for more than two days.
The last time my smartphone died on me, it only took me 24 hours and I had it replaced immediately because I couldn't stay more than 24 hours without having it replaced. This is because I have so many things that needed to be attended to in less than 24 hours or otherwise I would have a very serious problem.
