Yesim does offer unlimited data eSIM plans for South Africa. The provider lists several options ranging from 1‑day passes to 30‑day plans, with prices starting at $8.17 USD for a single day and going up to $75.87 USD for a seven‑day “Global Plus Package” that also covers additional countries. All of the South Africa‑specific unlimited plans are delivered on 3G or LTE networks, and tethering is allowed under each plan.
The unlimited plans are subject to a Fair Usage Policy: normal speeds may be capped, and heavy usage can lead to throttling. If a user is concerned about potential speed restrictions, they should contact Yesim directly to confirm whether the FUP applies to their chosen plan and to find out the typical amount of data that is available at normal speed before any throttling occurs.
