Where is the easiest place to buy and activate a pre-paid SIM card in Cape Town after arriving at CPT airport?
Are there any special requirements? (A local address, etc)
I was in South Africa earlier this year and rented a SIM card for my iPhone 5 at the Vodacom store in the Johannesburg Airport. You should be able to go into any mobile store off the street and buy a prepaid SIM card for your device. Make sure your device is unlocked and able to be used with another carrier other than the carrier you originally bought it through.
The only information I needed were my passport, home address, credit card, and contact information. They made copies of both my credit card and passport for their records.
