I have a new Galaxy s3. Most times when it shows 4g I get subpar speeds in the .04 to .2 mbps range. Its about the same speed when my phone is on the edge network. Only a few times have I gotten 5 to 10 mbps range while on the 4g network. I get full signal bars when doing these test. I'm on the $30 5gb monthly unlimited data plan which I just activated last night so it can't be throttled already. I'm new to t-mobile but isn't the speed suppose to be fast when connected to 4g or am I reading my galaxy s3 wrong?
