Monty eSIM does not provide any unlimited data plans for Sri Lanka. All plans listed by the provider are fixed‑data options with caps that range from 10 GB to 50 GB and validities of 15 days to 30 days.
Travelers who need a large data allowance can choose among the available fixed‑data options. For example, the 50 GB plan is valid for 30 days and costs $22.99 USD, the 20 GB plan is also valid for 30 days but is priced at $18.99 USD, and a 10 GB plan may be purchased for 15 days at $11.99 USD. Choosing a fixed‑data plan can be more cost‑effective compared to unlimited options, especially for heavy data users.
