Using a prepaid mobile phone, instead of a phone with a contract, is a great way to stay on a budget. Prepaid phones allows users to use only the minutes for which they have paid in advance without the option of going over, thus, avoiding costly overage charges. Now with the advent of Internet capable phones, many prepaid mobile providers are offering prepaid data plans. A data plan lets users send and receive emails, access the Internet and stay in sync with social networking sites. Understanding how to use your prepaid phone to send emails will keep you connected to your contacts.
