I have been using 3G since a month via 4500 plan. Location is Mumbai with 3 bars on Mtnl software. First 15 days I had pretty speeds of 2.5 Mbps. But since a couple of weeks, my speed gets stuck to 760kbps to 1 Mbps max. Early morning (7-9 am) I get speeds like 2 Mbps for a couple of hours. and then back to 1Mbps. Sent a email to CC to no avail. Any suggestions ? I think it could be the location of antenna, hence I keep my antenna near the balcony. Update: Latest speed test at 21:20h https://www.speedtest.net
