abesteSIM offers unlimited‑data eSIM plans for Oman. The plans under the “Middle East (8 Countries)” line list the data cap as Unlimited and cover Oman along with seven other countries. Validity periods range from 1 day to 30 days, with prices from $6.34 USD for a 1‑day option up to $189.90 USD for a 30‑day option. The plans advertise 5G coverage, but notes that speeds may be throttled after heavy use, so travelers concerned about potential speed restrictions should contact abesteSIM to confirm the fair‑usage policy and typical data available at normal speed.
