So what's everyone's average download speed on the Thunderbolt using the speed test app??
you're probably doing nothing wrong. the speeds will vary quite a bit, depending on your location. phoenix happens to have a GREAT network here and i'm right in the middle of the city. they advertise "up to 12-15".....but i've seen them as high as 25-30, and much lower as well. 4 is probably on the very low end of the average and likely is barely fast enough to call it 4g, but that's still 3+ times faster than the average 3g speeds.
What am I doing to slow my phone down so much then??? I'm averaging 3-4 mbps download on 4G...Is there something wrong with my SIM card you think? Or did I do something to my settings and just don't know about it?
If you're using the speedtest app, those upload numbers aren't accurate as the app isn't corrrectly measure the upload speeds over LTE.
