Yes, Earth Esim sells unlimited data eSIM plans that work in South Africa. The unlimited options are priced between $3.99 USD for a 1‑day plan and $69.99 USD for a 25‑day plan, and the validity ranges from 1 day to 25 days. Each plan carries the same terms: tethering is allowed, but speeds may be throttled after heavy use, and the maximum speed is capped at 1000 kbps.
Because these plans have a Fair Usage Policy that can reduce speeds after substantial data consumption, users who are concerned about potential throttling should contact Earth Esim directly to confirm the typical data amount that remains at normal speed and to verify the policy’s limits.
