People who really, really want to save money not only use cell phones, but buy used cell phones.
How does using cell phones save you money? With cell phones you can control how much money you spend each month by prepaying for minutes, or by tracking your minutes with your carrier.
With data plans even cheaper, people have begun using cell phone’s data to communicate (which is often cheaper since it’s not prioritised by networks and takes up less room; think a 20 word text vs. connecting a phone call, chatting for five minutes, etc.).
To save more money, used cell phones are a great boon. Free of contracts and carrier affiliations, used cell phones can help to cut a few dollars off the expense of buying and using a cell phone. Used cell phones still offer the same great quality, and can often be bought as refurbished cell phones.
If you really want to save money, older used cell phones (older refurbished blackberries or nokias) have great durability and function and a huge discount of newer, trendier phones.
Some websites will help you analyze your phone bill, but for a fee. Otherwise, careful planning on cell phone use is required.
