You search for a WiFi tethering app for your phone and set up your phone as a WiFi hot spot then you will be able to email or browse the Internet using your phone's data plan. Remember it does count towards your data usage on your phone. You may have to try a few different apps to find one that is compatible with your phone, but there are apps available that work on phones without root. I must admit that my phone is rooted so I have easy access to WiFi tethering.
