I'm experiencing really strange problems with a contract data sim card. I'm currently in the middle of the Karoo, got a Huawei B660 router attached to a LPDA 11Dbi antenna and up until yesterday the connection was rock solid. The router has got the farmer's contract data sim card in it. When I do a traceroute there is massive packet loss to any destination I do a traceroute to.
However, when I swop in my own personal prepaid sim card with a data bundle loaded on to it and do a traceroute to the exact same destination, the traceroute is flawless, no packet loss whatsoever and the connection works great.
How can it be possible that connecting to Vodacom with a contract sim card can have completely different network conditions to a prepaid sim card? And how can I fix this? It's the same router, same antenna, pointing to the same tower, just different sim cards.
