Bordersim does not provide an unlimited data eSIM for Yemen. The available plans are fixed data bundles that include a set data cap and a validity period. For example, bordersim offers a 20GB plan that is valid for 30 days, a 10GB plan also valid for 30 days, and smaller 5GB or 3GB options with varying validity lengths. These fixed plans can be more cost‑effective for most travelers, unless a user requires very heavy data usage that could exceed the set allowance.
