With Vodacom and MTN launching HSPA and HSPA+ services on their networks many users will find their modems incapable of taking advantage of the additional bandwidth.
When taking out a mobile data contract you may have a choice of modem which seems arbitrary. Taking the cheapest modem in a technology class (HSPA, HSPA+) might seem to make sense, but could result in being unable to make use of the latest technology MTN and Vodacom have to offer. The modem might say “HSUPA support,” but without reading closely one may not notice that it supports 2Mbps upload speeds and not 5.76Mbps.
The following information has been supplied by MTN's retailers and Vodacom. Where no price is provided it means that the networks state that they no longer sell the device. All prices are the cash price of a modem on a prepaid service and are inclusive of VAT.
