When a shared plan tends to win, and when it does not.

Putting the whole family on one phone bill sounds like it should save money, and often it does — but not always, and not in the way the ads imply. The savings depend on how many lines you have, which carrier you are on, and who controls the account. This guide walks through the real math in plain words. If you would rather I look at your situation directly, the number is (330) 200-8042.
