With the internet, travel and laptops it is easiest to just use data roaming from your network provider. This has become a nightmare for travellers when they return home and get astronomical bills for data usage. For some examples have a look at a few of these links:

These rates are crazy. Some phone bills have come back in excess of ZAR30 000. So beware and bewarned rather not to use your 3g card or cell phone abroad for data.
