nextSIM eSIM Data Plans for Southeast Asia

nextSIM does not provide any truly unlimited data eSIM plans for Southeast Asia.
All plans that include “Unlimited” in the name actually have a fixed data allowance—either 1GB or 2GB per day—after which the speed drops to a reduced rate (512kbps or 2000kbps).

If a traveler prefers a higher data volume without the speed throttling, nextSIM offers several fixed‑data options. For example, the eSIM GLOBAL 50GB 30Days Premium plan provides 50GB of high‑speed data for 30 days, while the ASIA + Australia 20GB 30Days Economy plan gives 20GB for the same period. These plans can be more cost‑effective for users who need substantial data for travel across Southeast Asian countries.

nextSIM does not provide eSIM plans with a local phone number or SMS capability for Southeast Asia. The provider’s offerings in this region are data‑only plans, so travelers will have to rely on internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage to communicate over the data connection.

Plans entitled eSIM ASIA + Australia Economy, eSIM Unlimited Standard Asia, and eSIM Unlimited Standard Global each include coverage in Indonesia, Malaysia, Singapore, Thailand and Vietnam; the eSIM Oceania Premium plan adds the Philippines to that core group, while the eSIM GLOBAL Premium plan extends coverage to Cambodia and Laos in addition to the same core Southeast Asian countries. The eSIM GLOBAL Economy and both instances of eSIM Unlimited Plus Global likewise offer service in Indonesia, Malaysia, Singapore, Thailand and Vietnam. No plans cover Brunei, Timor‑Leste or Myanmar.
