I have a MTN branded Fastlink E620 data card that I use for internet at home. I can connect via 3G and normally get speeds in the range of 15-20 kB/sec using a MTN prepaid sim card. Recently a friend of mine came for a visit and he used his laptop to connect using his own MTN branded E620. I was amazed to see hom consistently get > 100 kB/sec downloads. So as a test we plugged his E620 into my computer and I got the same > 100kB/sec download speeds. The only difference between the two cards is that I have a prepaid sim card and he has a expensive contract sim card. So what I want to know is; is MTN giving better quality service to their big spending contract clients than their humble prepaid clientbase?
