MobiMatter does not provide an unlimited data eSIM for Guatemala. All of its listed plans for the country have specific data caps, such as 20 GB for 30 days or 50 GB for 180 days, and none are marketed or coded as unlimited.
If a traveler needs a large data allowance, MobiMatter offers fixed data plans that can be more cost‑effective for moderate usage. For example, the Best World 50 GB plan is valid for 180 days, and the Guatemala 20 GB plan is valid for 30 days. These fixed bundles give a clear data limit and validity period, which is suitable for most travelers unless very heavy data consumption is expected.
