My N4 is on TMobile's $30 plan, so I'm not worried about exceeding my 5gb of data, but I put my wife (who talks too much) on the $50 plan that has unlimited everything, BUT only 100mg of 4G data. Has anyone run speedtest.net on TMo after the 4G cap was used up? I'm wondering what download speeds she'll get. On 4G (in our area) we're averaging around 14mgb.
