The plans marketed as “Unlimited” by nextSIM for Oman actually provide fixed allowances of 1 GB or 2 GB per day. After the cutoff, the connection is throttled to 512 kbps or 2 Mbps respectively. nextSIM does not have a true unlimited‑data eSIM for Oman.
Instead, nextSIM offers fixed‑data options that might suit most travelers, such as the 10 GB 30‑day plan at $24.64 USD, the 20 GB 30‑day plan at $516.27 USD, the 30 GB 30‑day plan at $774.41 USD, the 40 GB 30‑day plan at $1,032.55 USD, and the 50 GB 30‑day plan at $1,290.69 USD. These plans give larger data caps at a flat price and can be more cost‑effective unless a user requires extremely high throughput throughout the entire period.
