There are no unlimited data eSIM plans for Azerbaijan offered by yaySIM. Travelers can choose from fixed data plans such as the AZ_20_30 plan, which gives 20GB of high‑speed data for 30 days, or the AZ_10_Daily plan, which provides 10GB for one day. If a passenger needs a larger data allowance, other fixed plans with 20GB for up to 90 days are also available, such as GL‑139_20_90. These fixed data plans can be more cost‑effective for most users, unless the traveler expects very heavy data usage where a larger or pay‑as‑you‑go option would be preferable.
