nextSIM eSIM Data Plans for Southeast Asia

nextSIM does not provide truly unlimited data eSIM plans for Southeast Asia. All plans that carry the word “Unlimited” in their name still have a fixed data cap—typically 1 GB or 2 GB per day—and a reduced speed of 512 kbps or 2000 kbps once that limit is reached. For travelers who want a larger, continuous data allowance, nextSIM offers fixed‑data plans such as the eSIM 20GB 30 Days Asia plan or the larger eSIM GLOBAL 30GB, 40GB and 50GB 30‑day Premium options, which deliver 20 GB to 50 GB of data over 30 days without throttling.

NextSIM does not provide an eSIM plan for Southeast Asia that includes a phone number with inbound or outbound SMS capability. All plans available from this provider for the region are data‑only; they offer high‑speed internet on 4G or 5G networks but do not include voice or SMS services. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

NextSIM offers several eSIM plans that cover Southeast Asian countries. The plans “eSIM Asia, ” “eSIM Asia Standard Economy, ” “eSIM Global, ” and “eSIM Unlimited Standard Global” include coverage in Indonesia, Malaysia, Singapore, Thailand, and Vietnam. The “eSIM Oceania Premium” plan adds the Philippines to that core list and covers Indonesia, Malaysia, Singapore, Thailand, and the Philippines. The “eSIM GLOBAL Premium” plan and the “eSIM Unlimited Plus Global” plan expand coverage to include Cambodia and Laos in addition to the same eight core destinations, offering Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam. These are the only Southeast Asian countries listed in the nextSIM dataset.
