Yes, Truely provides unlimited data eSIM plans for South Africa. The plans are available in validity periods ranging from 1 day to 30 days, with prices between $7.92 for the 1‑day plan and $112.86 for the 30‑day plan. Each plan supports 3G, 4G, and 5G networks, but speeds may be throttled after heavy usage in accordance with the fair‑usage policy, meaning that normal speed can be reduced over time.
Because of this fair‑usage policy, the actual amount of data available at full speed may decrease after a period of heavy use. If you want specific details about how much data is typically available at normal speed for a particular Truely plan, or whether a particular plan has stricter limits, it is best to contact Truely directly for clarification.
