After using the SIM Toolkit on an Android phone to retrieve the APN settings automatically, I see that Streaming and WAP are created in addition to the usual Internet and MMS APN connections. Does anyone know what they are useful for? The best I could find on google was this explanation:


Most mobile networks offer two different APNs: one for full internet connection and another that is a more limited set, often used for WAP only. The WAP connections can be charged at a lower rates, partly because they use less internet bandwidth, but mostly because of the imponderables of marketing and pricing!
