AeriSIM does not provide any unlimited data eSIM for Oman. All plans are fixed data bundles, meaning the data allowance is capped and must be used within the specified validity period. For travelers needing large amounts of data, AeriSIM offers fixed bundles such as the 50GB plan available for 3, 5, 7, 10, or 15 days. These plans can be more cost‑effective for users who consume moderate to significant data and prefer a predictable data limit.
