Fair warning. If your provider has a one price plan (either so many a month or unlimited) it's worth it. Especially has he gets older.
What plan do you use? I’m thinking of going with AT&T...our plan is pay as you go and it’s costing us about $70 a month for the three of us and we don’t even use it as much as we’d like...no free minutes or free weekends or anything like that.
