This call isn't one we can make. It's up to parents what access to the outside world via a phone a child should have. While the age for having a cellphone seems to get lower and lower, it's best to check with the parents before purchasing a cell phone as a gift for a 13-year-old boy. If you do get a 13-year-old boy a cell phone, you'll likely be the favorite relative at least until next Christmas. You should make sure there's a plan to cover the monthly costs associated with a cell phone as well.\r
