My son asked for his own mobile phone when he was in first grade. We bought the cheapest Nokia phone and although it doesn't include headphones for him to listen to his favorite songs, my son was happy with it for a few months. Since he's not allowed to bring a mobile phone to school, he didn't use it for more or less two years.
Now he's in 4th grade and is asking for a new phone. I told him to use his old mobile phone. Although the casing looks old, it's still working perfectly fine. I won't spend money on something that he doesn't really need anyway.
How old is old enough to use a mobile phone anyway?
