eSimfly does not provide a true unlimited data eSIM for Azerbaijan. The plans with “Unlimited” in their name give 3 GB per day and then throttle the speed to 1000 kbps, so they are not high‑speed unlimited. Travelers who need a higher, unthrottled data allowance can choose fixed‑data plans, such as the 50 GB 30 days plan priced at $83.47 USD or the 20 GB 30 days plan for $41.26 USD. These fixed plans offer larger data bundles at a set validity and can be more cost‑effective for most users.
