Access Point Names are composed of several settings. These settings are essentially text fields that you must fill in in order to connect to data services. APNs exist because carriers broadcast and receive data over government regulated radio frequencies. Each phone must be specially configured to use these settings or otherwise potentially suffer from data connection issues, such as the inability to send MMS or use mobile data. iTech Unlimited Phone Data Settings
