I've been using a MTN USB HSDPA modem (the little black one) for almost a year now without any particular issues. I would sincerely recommend that you don't buy your modem from MTN or Vodacom and rather just look for a normal non-branded (and without modified firmware) modem. The particular model that you're looking for is the Huawei E220 USB HSDPA modem (the “bug” modem).About the only other thing to give any serious thought to is whether or not you'll get your bandwidth on a contract or via pay as you go. The pay as you go service on MTN is an absolute bloody nuisance to deal with – to convert minutes to bandwidth, you must put the SIM into a cellphone and phone 141 and then go through the voice prompts to make the conversion. To make matters even more irritating, you can only convert airtime to bandwidth once per month on any given SIM card. As a side effect of this, I am now the proud owner of 4 MTN SIM cards which are rotated so that I can exceed their 2Gb per month idiocy.Other than daft corporate policies and absurdly expensive bandwidth cost, I am very happy with my internet connection.
