EtravelSIM does not currently provide any unlimited‑data eSIM plans for Southeast Asia. Its offerings are limited to fixed data packages that specify a set data quantity and validity period.
Travelers looking for larger data allowances can consider the 50GB plan for 30 days, priced at $80.99 USD, which covers Indonesia, Malaysia, the Philippines, Singapore, Thailand, Vietnam, and five additional countries, or the 20GB plan for 30 days at $27.00 USD, which covers Indonesia, Cambodia, Laos, Malaysia, the Philippines, Singapore, Thailand, and Vietnam. These fixed data plans can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer.
