ByteSIM does not offer a truly unlimited data eSIM for South Africa. Every plan listed in the provider’s catalogue has a hard data cap, and the plans that carry the word “Unlimited” in their names actually provide 1GB per day with a reduced speed of 10 000 kbps once the daily allowance is exceeded.
Travelers who want larger data volumes can choose fixed data plans. For example, the South Africa Unlimited Data for 5 days plan gives a total of 5 GB (1 GB/day) with speed throttling after each daily limit, and the South Africa 50GB for 7 days plan offers 50 GB over seven days. These plans require that the data be used within the specified validity period.
