No, nextSIM does not provide a truly unlimited data eSIM plan for Turkey.
All of the plans labeled “Unlimited” in the nextSIM catalog are in fact fixed‑cap packages that offer either 1 GB per day or 2 GB per day, with a reduced speed applied once the daily limit is reached (512 kbps for the Standard line and 2000 kbps for the Plus line). For example, the “eSIM Unlimited Standard 30 Days Turkey” delivers 1 GB/day for 30 days, while the “eSIM Unlimited Plus 30 Days Turkey” offers 2 GB/day for the same period.
Travelers who need a higher or truly unlimited data allowance should look at the fixed data plans such as the 50 GB 30‑day economy option, which provides a larger pool of high‑speed data. Choosing a fixed data plan can often be more cost‑effective than paying for a daily “unlimited” plan that throttles speed after a small daily quota.
