Good to hear from you. You’ll find a whole bunch of iPad enthusiasts in this Forum who are only too willing to help other iPad owners and to hear of their experiences. Don’t be afraid to post any questions you may have or use the ‘Search’ button near the top of the Forum web page. I usually find I discover one new interesting and useful piece of information about my iPad every day - and often not even what I was looking for!!
I saw your problem about a PDP Authentication Error. This means that Vodacom have not yet activated your SIM. Sometimes it takes a few hours for their admin to input your details into their system and for that authorisation to make its way through to the network side of things. If it persists for more than a few more hours, then you need to contact Vodacom again and ask them to authorise your account.
Hope to hear from you soon with your thoughts about the iPad.
Have fun and enjoy your iPad
