I live in the metro Detroit area and for the last 6 months ( or more ) I've been unable to see above 15Mbps
I have unlimited data and tried at the beginning and end of cycles with no variance. Different phones as well.
I have several customers who are experiencing the same issues. Just wanted to check to see if it's a network problem before filing a complaint with the FCC. ( Promote/Promise 4G with a failure to provide adequate service )
