Text messaging, also called short messaging service (SMS), is wildly popular, but it has some problems. The biggest complaint is the cost. Most provider plans charge a fee for a certain number of texts per month, and if you go over that amount, additional text costs can add up quickly. Another disadvantage of texting is that you can never be sure how quickly your message will travel, so you may think a message has gone through, but the recipient hasn't seen it yet. Further, SMS isn't really versatile. You only can send videos or music if you have enhanced service.
