Because you’ll access the internet using a mobile data plan, it’s important to consider the amount of data that you believe you’ll use and purchase a plan that will accommodate your listening habits. Many of the streaming services stream the data at different rates depending on the kind of connection you make. At home and over a cable modem, the service may stream at 320kBPS, but over a mobile data connection, the stream will be lower resolution. Depending on the bit rate, the sound quality may suffer, but you’ll use less data.
To get an idea of how much data you’ll need to purchase to support your music streaming habit, consider that a 10GB data plan will allow you to stream the best resolution available (320kB/second) for about 70 hours if that’s all you do with your phone. Data consumption rates for video are much higher.
