eSIMCard does not provide a true unlimited‑data eSIM plan for Oman. All plans that list “Unlimited” in the name actually give a fixed allowance, such as 1GB per day for the duration of the validity period, and after the data is used the connection speed drops to a throttled rate (for example to 500 kbps or 512 kbps). Therefore, there is no plan that offers high‑speed data without any limit, even though the name suggests otherwise.
Travelers who need unrestricted data can choose from eSIMCard’s fixed data offerings. For instance, a 50 GB plan for 60 days is available for $218.06, and a larger 100 GB plan for 180 days is offered for $185.68. These plans deliver high‑speed data throughout Oman without a hard cap, and may be more cost‑effective for users who anticipate heavy data consumption.
