TFW is a short form of TracFone Wireless. This is a label attached to your iPhone when your device is using the TracFone cellular network. When you observe the combination TFW it only means that your cellphone is connected to TracFone or its alliance, such as Straight Talk, Net10, or Simple Mobile. The TFW label does not show something technical or hard to understand; it only indicates through which network carrier you work. This is not a mistake and it is nothing to get alarmed about.
