Where the 7-day figure comes from
The typical profile assumes half an hour of navigation, an hour of social media and half an hour of browsing each day, plus 30 to 100 MB of messaging and background traffic. That is 160 MB to 835 MB a day, so 7 days comes to 1.1 GB at the low end and 5.8 GB at the high end. The spread is mostly social media: feeds without video use about 120 MB an hour in the carrier figure we use, while feeds full of short video reach 700 MB an hour.
| Activity (typical profile) | Per day | Over 7 days |
|---|---|---|
| Navigation | 3 MB–5 MB | 18 MB–35 MB |
| Social media | 120 MB–700 MB | 840 MB–4.9 GB |
| Browsing and email | 8 MB–30 MB | 53 MB–210 MB |
| Messaging, email and background apps | 30 MB–100 MB | 210 MB–700 MB |
| Total | 160 MB–835 MB | 1.1 GB–5.8 GB |
Rates: navigation and social media from Consumer Cellular; browsing and email from AT&T's data calculator; all checked 2026-10-19. Full list on the methodology page.
If you stream or call: the heavy profile
Add half an hour of video, a quarter hour of video calls and an hour of music a day on mobile data, with navigation and social media at the higher setting, and 7 days in South Africa rises to 4.6 GB to 29 GB. Video streaming alone spans 875 MB to 8.8 GB over the trip, because the Netflix app's Automatic setting uses about 250 MB an hour while HD streaming uses about 2.5 GB. If that is you, plan for 30 GB or an unlimited plan.
Is South Africa cheap or expensive for mobile data?
About average. South Africa ranks 39 of 60 destinations here for price per gigabyte, with the best fixed plan at $1.5 per GB (median $1.3, range $0.8 to $8.8). Unlimited plans start at $3.3 a day, rank 53 of 60; for a 7-day trip that is $23.1, which undercuts buying the heavy-use 30 GB at the fixed rate.

Plug and voltage in South Africa
South Africa uses type C, M and N sockets at 230 V and 50 Hz, per WorldStandards.eu (cross-checked against a second reference; see the methodology). A US type A or B plug does not fit, so pack an adapter. The voltage is higher than the US 120 V; phone and laptop chargers marked 100–240 V handle it, but a hair dryer or other single-voltage device does not. Details on the South Africa plug page.
