It's difficult to get by without a cell phone today, but with a little research you can find an affordable plan that fits your needs. If they're up for it, join a family cell phone plan with your parents. It's usually much cheaper for everyone involved than having separate plans. If you're on your own, check out websites that offer side-by-side comparison charts of different cell phone plans. You should also avoid text messaging. Before you know it, you could rack up hundreds of dollars worth of texts when you could have communicated the same information for much less. Remember, phone companies charge both the sender and receiver of text messages, so let your friends know if you don't want them texting you five times every class. Send out e-mails or use free networking Web sites like Myspace or Facebook.
