Deleting contents of iphone 4s

[bingbang001]

Just bought an iphone 6 and want to sell my 4s, however the wifi does not work on the 4s and i cannot delete the contents. Any ideas of how i can do this ?

Go to settings - general - reset - erase all content and settings.

This is on iOS 8 - if you are still on an earlier version it might be slightly different but the option will be there somewhere.

Hi

Great advice by @jeffkinn

Here is 's help link https://support.apple.com/en-gb/HT201351

You'll also need to move your number and tariff from the micro sim card to a Nano Sim Card that fits the iPhone 6.

The best place fo a sim swap is in a Vodafone store. The new sim should be up and running in minutes.
