shibaSIM does not provide a truly unlimited high‑speed data plan for Tunisia. Its offerings for the country are fixed data plans that provide a daily high‑speed allowance (0.5GB, 1GB, or 2GB) and, after reaching that daily cap, the connection is throttled to a reduced speed of 128kbps.
Travelers can choose from a range of these fixed‑data options, such as the 2GB/day plan for 3 days at $20.49, the 1GB/day plan for 10 days at $40.89, or the larger 20GB plan for 30 days at $41.99. These plans give a set amount of high‑speed data for a set validity period, which can be more cost‑effective than an unlimited offering for users who are not heavy data consumers.
