Totally unreliable. Connection problems. Frequent and long downtimes. Works only 10 lucky days a month. Worst customer support. Need to wait 30 minutes everytime when you call them. Support representatives give one fixed answer that they are working. For God’s sake how much time it takes to fix connection problem issues? It has been 3 months now and still I get internet only on lucky days. Too much unreliability. Can not do office work at all.
