GulfData does not provide a truly unlimited data eSIM for Eswatini (Swaziland). The plans that carry the “Unlimited” label actually give 1GB per day at full speed and then throttle to 512kbps once that daily amount is reached, so the data is not unlimited.
Instead, GulfData offers fixed data plans for Eswatini. For example, a 20GB plan valid for 30 days costs $120, and a 10GB plan valid for 30 days costs $68. These fixed data plans give a larger data allowance without the speed reduction that applies to the “Unlimited” plans, and they can be more cost‑effective for most travelers.
