11. Cell phone
It seems like cell phone plans have becoming increasingly complicated with inclusions and exclusions over the years. Usage charges are a major source of hidden fees. These can include subscription services from third parties. Some are monthly texts that look like a wrong number but you’re actually being charged for dating advice or horoscopes. You can usually stop them immediately by texting STOP back. Then call your service provider to make sure these fees are removed retroactively.

12. Frequent Flyer Miles
All mileage point programs vary in both offerings and fees so read the fine print and, when in doubt, call the 1-800 number before booking anything.
