pcw, no. it's not shaped, nor are any ports blocked.
We have found the odd situation where certain applications appear not to work over GPRS or 3G and at first glance it appears like port shaping. For example, certain VPN clients as discussed in another thread.
This is not the cause though.
Is this a general question, or do you have specific applications you're having a problem with?

There would hardly be any sense in shaping the ports imo - the target market is a businessman / traveler and I wouldn't think they would be too much P2Ping or am I wrong?
Shape status...
I know this is a pretty old thread, but has anything changed concerning the shaping of 3g??? I tried to download a 20mb(international) file and it start of fast, like 45kb/s and then after about 30 seconds is just constantly idles at about 8kb/s.
The file server is fine because I experienced the same with all the other servers I tried to download from.
Could it just be my coverage??? I'm on the border of pta-east and bronkhorstspruit. I've been using 3g for 6 months now without any problems at this location, until now that is.
Thank you.

I don't have HSPDA. I have a 3g handset with 4bar reception. My problem is that the download speeds decreases considerably after about 30secs.
Download time: 134.015 seconds
Size of file: 500 KiloBytes
Estimated line speed: 30.4 (kilobits/second)
Estimated line speed: 3.7 (kiloBytes/second)
This is with 3g with 4bars!!! The download speeds starts of at about 30kb/s and the suddenly decreases to 3kb/s-8kb/s...
My system setup is exactly the same as it was before.

Yes, in a sense you're correct but the normal definition of shaping is not normally applied to the total connection speed, but rather to specific applications being used.
With a 3G card, the modulation and encoding limits you to 384Kb/s so back-end speed limits will only be applied if you use a HSDPA card on a 3G contract.
Just to re-iterate:
1) There is no port or protocol shaping on Vodacom's services.
2) You'll get maximum speed dependant on network conditions.
ah, "dependant on network conditions" i guess explains alot.... 1.) not enough 3G cells to cater for current demand, and 2.) not enough back end bandwidth to cope with current load. I think we can safely assume the 2 statements to be correct, on prevision that Alan Knott-Craig does not dispell this rumour. Cause almost everyone is complaining about the same thing at the moment.
I also STRONGLY think that the load on 3G cells is getting VERY high. I keep getting bumped off a 3G cell, and then when trying to connect get a error 619 for a few attempts and then connect fine again. This to me sounds like the cell I am connecting to is overloaded...... and thats CPT CBD.
Again, unless Vodacom deny the above, I think we can all safely assume it to be correct. I have provided v3g with the details but to date, no feedback... perhaps because the only feedback is negative??

Got your info, thanks.
Don't think you're wrong, the network growth is accelerating faster than the capacity can be upgraded, in certain places.
When HSDPA rolled, a certain number of HSDPA connections were predicted and spare capacity was built in to handle this extra load. These would have come from early adopters, probably most of this forum!
Then, off course, Vodacom decided to do the free swapout. This obviously accelerated the takeup of HSDPA radically as everyone now jumped the 3G ship. This placed new challenges on getting capacity in, especially transmission in very short timeframes.
In certain areas capacity upgrades cannot keep up with this uptake and quadruple jump in throughput.
It's obviously being addressed with utmost urgency.
