There are many instances when one would use a WiFi headset. These instances include when one is not getting services for one's phone. However it is also useful when one is running low on how much data one has left.
like all models of the iPhone you only need wifi access if you want to use the wifi facility on your handset. Using the wifi mode allows you to use your home or other source of broadband ADSL, rather than using the data allowance provided as part of your network package from your network provider. If you have unlimited broadband then using wifi is free and there is no limit of the data used home or other wifi such as free hotspots. Also certain applications use the wifi network such as iMessaging which is free also when used via the a wifi network. in essence you do not need to enable the wifi mode on your handset but it has it's advantages, namely cost savings on data allowances.
