I am heading to Australia again soon. Last time I was there, I bought a VF Aus SIM card at the airport. It worked fine for voice and SMS, but when it came to accessing the Internet I couldn't do it. I checked the VF Aus website and it said I needed to input an APN.
Would someone be kind enough to explain (very slowly) what an APN is (I think it's a password? I see 2degrees' APN is "internet") and how I go about inputting it into my phone when I arrive?
