im using u28 since july. speed are amazing that time.... but become slower and slower... today at peak hour hardly to get 1mbps... vs when i start using it, can get 8-10mbps peak hour and steady 21mbps at non-peak. this month they promoting +1gb.. some of my neighbour that i know, 50% switched to u-mobile...so... expecting worst. maybe time to report about network performance...
