ZenSim does not provide a truly unlimited high‑speed data plan for Saudi Arabia.
The plans marketed as “Unlimited” give a daily allowance of 3GB; after the limit is reached the speed drops to a reduced level, so the plan is not unlimited in the sense of unrestricted high‑speed data.
Instead, ZenSim offers fixed data plans that may be more cost‑effective for travelers. For example, a 20GB plan can be bought for 10 days at $30.00 USD or for 30 days at $33.00 USD, and a 10GB plan for 10 days is available for $21.00 USD. These fixed‑data options provide a larger, non‑throttling data supply if a user needs more than the 3GB/day offered by the “Unlimited” line.
