Manually switched to GR vf and I get either 3G or LTE and top speed is about 15-20 Mbps down but only 1-3 Mbps up.
Very high pings on both, in fact latency fails in the Speed Test Net app a few times.
In my hotel room right by Monastiraki Square, I get about 11 Mbps down on GR vf. Yet when I tether, the most I'm getting is about 2 Mbps.
I tried to buy. SIM card from Cosmote but they were out.
Going to the islands now and it will probably be no better.
Hotel wifi is under 1 Mbps.
Follow up: very next morning I tweeted T Mobile Help. I was using DM but while waiting, I switched back to Cosmote and I was getting 24/14!
And it carried through to tethered devices.
Not sure what changed but was happy about it.
Then I went to Mykonos, where the hotel is a bit east and above the center of Mykonos town.
Was only getting 3 bars in the lobby but still decent speeds. Much better in the town.
In the room though, I was only getting about 2-3 Mbps. Switched to GR vf again and got about 15/4.
