I don't know if I am missing something simple, but I have taken up the R149 promotion and have been trying to use my Nokia E7 as a modem for the PC. It connects at 3.5G and everything and initially it runs smoothly, but as soon as it has to download a piece of data larger that 700KB or 800KB or so, it stops and the line is unresponsive, necessitating me having to redial. This means I can't watch Youtube, download larger email attachments etc, which renders it useless.
Am I missing something obvious? Are there other people who have been having problems?
