Here is a typical Speedtest result obtained with this card:

* Latency is not wonderful, but OK.
* Download Speed is excellent, no problems there.
* However, 48kbps is the best Upload Speed I got from several tests.
While using this connection to browse the web (including posting to Geekzone), performance is pretty good, but the 48kbps upload speed pretty much kills outgoing Skype audio. Incoming audio however is fine.
If I switch the laptop to WiFi without making any other changes, it connects to my Kordia Extend Wireless 512kbps Down/128kbps Up connection and Skype works perfectly in both directions.
The Sierra Wireless "Watcher" software shows 3 out of 5 bars for signal strength (-89dBm EVDO) and it also shows that an EVDO High-speed Data Session is in use.
Therefore, so far as the 595 AirCard is concerned, the connection to Telecom's T3G network appears to be working as expected.
So, my questions are:
Why is the Upload Performance so poor when the Download Speed is so good?
Because I am getting a 1Mbps Download Speed, I would have thought this means I am using an EVDO Rev.A signal. Is this correct?
Any suggestions would be appreciated, and meanwhile: Many Thanks once again Mauricio for loaning me this card, it's a very cool piece of kit

UPDATE: Just tried another speed test as follows:

The Upload Speed seems to vary quite widely depending on exactly when I run the test. Could other network activity (from other users in the local vicinity) be affecting this?
On the strength of this much improved result, I tried Skype again, and sure enough, the Outgoing Audio was much better although some dropouts were still evident.
It's strange that the Upload Speed is so variable, whereas Download is consistently above 1Mbps which is pretty damn good for mobile broadband
