So I live in Miami and I have a monthly (no contract) unlimited 4G cell phone phone with Metro PCS for $60 a month (flat rate). I'm trying to cut costs on monthly bills, and I'm thinking about going with the 3G monthly plan for only $40 a month. Well, it's first 500MB at 4G and then 3G beyond that. The only thing I do on my cell phone is internet and streaming music/radio. I bike and run a few hours a day, so streaming music/radio is pretty important. I use Spotify for albums, Pandora for artist radio, and iHeartRadio for local sports radio. Do you think I'd still be able to do all these things on a 3G network, or should I pay the extra $20 a month for unlimited 4G?
