Data Downloads and Speeds

Plans speeds are shown in downstream/upstream format and speeds are theoretical network maximum speeds. Actual speeds may be less due to a number of factors including network configuration, line quality & length, exchange type, customer premises interference, traffic and equipment. Speed is reduced to 64k/64k for the remainder of the billing period once the monthly allowance is reached. Data downloads and uploads are counted. The renewal day for your monthly data quota is the first day of the month.
