In the past 2-3 months I have been struggling with Vodacom 3G services, connections is always disconnected and even when the connection is active sometimes there's no data (no internet surfing possible) until manually reconnecting again (manually disconenct and connect). After reconnecting, surfing is again possible but only for a few minutes then no data is possible again. And as said, connection also disconnects by itself. This problem is all through the day, even using the service at night (off peak) the problem exists.
Before this, I have been using the same modem/aircard dongle at the same place/location and it was better. Now, it seems that Vodacom coverage has shrunk and even worse, the data throughput is unstable in connected mode.
The solution seems to be manually setting the modem/aircard to GSM and then the problem seems to disappear. I have done this many times when I need to urgently send an email while 3G connection is not possible but staying in GSM is just too slow. I feel cheated when using GSM because I am buying data bundle and the faster the connection the better for me since I am paying per data usage (Mb).
I have tried searching on the Vodacom website where I can submit this complain but it seems that there is none.
To Vodacom management, please fix your network! Don't wait until Cell C and MTN take you over...
