Yes, AeriSIM offers unlimited data eSIM plans that cover Lithuania. The plans range from 1 day to 30 days, with prices from $2.21 USD for a 1‑day plan up to $40.89 USD for a 30‑day plan. All unlimited plans allow tethering and may be throttled after heavy use; the maximum speed is 10 000 kbps for the 1‑day plan and 5 000 kbps for the 3‑day to 30‑day plans.
Because the plans are subject to a Fair Usage Policy, speeds can be reduced after a certain amount of data is consumed at normal speed. Travelers who need confirmation of the typical data volume that remains at full speed or who want to understand the exact throttling thresholds should contact AeriSIM directly.
