Does Roamless offer unlimited data eSIM for Southeast Asia?
Roamless does not provide any unlimited data eSIM plans for Southeast Asia. All available plans are fixed‑data packages. For example, a 20GB plan for 30 days costs $47.95 USD and covers Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. Another option is a 10GB plan for 30 days at $35.95 USD, which offers the same regional coverage.
