MoodSIM does not provide a genuinely unlimited data eSIM for Yemen. The plans listed under the name “Yemen Unlimited” give a high‑speed data quota that is capped at 1 GB, 2 GB, 3 GB, 5 GB, or 10 GB per day; once the quota is reached the speed drops to 1 Mbps or 512 Kbps. Travelers who need more unrestricted data can choose a fixed data plan, such as the Yemen 20 GB 30 Days or the Yemen 10 GB 30 Days, which offer larger data allowances for a set validity period without throttling the speed until the allowance is exhausted.
