Thanks Vodacom3G,
The GPRS network has been very dodgy since last night around 20h00. The two GPRS modules I have in the field had difficulties to stay connected. I also found a very interesting thing:
The one module connected with IP 196.207.45.253 and disconnected and then reconnected with IP 196.207.45.254. The module then lost sync with my server but remained connected to the GPRS network but no data throughput. I had to hard reset the module to reconnect.
The IP's are the NAT IP's on internet APN.
The GPRS data throughput in the Vaal Traingle has been very slow lately. I'm shifting small amounts of data but the data speeds are evident.
Thanks for the heads up
