I notice that my 3G data is very good only late at night to 6am. It is very terrible during the day; I get only 300 or 400kps during the day. At night I got 1.5mbps or 2mpbs. Do you know why? Is it because more people using the data during the day that slow down the data bandwidth and at night less people use the data, that is why I get a good data range.
