Strong eSIM eSIM Data Plans for Southeast Asia

Strong eSIM does not provide an unlimited data eSIM for Southeast Asia. All of its current plans for Southeast Asia have a fixed data cap. For example, the 50GB plan for 180 days covers Indonesia, Cambodia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam and costs $112.90 USD, while a 20GB plan for 30 days is available for $50.90 USD and covers the same seven countries. These fixed‑data options are offered because they can be more cost‑effective for most travelers, unless a user requires a large volume of data and prefers an unlimited plan with a different provider.

Strong eSIM does not provide Southeast Asia eSIM plans that include a phone number or SMS capability. Their offerings for this region are data‑only plans, so you cannot receive or send SMS through the eSIM itself. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice calls and messaging without a traditional phone number.

Strong eSIM offers a range of eSIM plans that cover several Southeast Asian countries. The Asia (7 areas) /Day, Asia (12 areas) /Day, Asia‑20, and Global (120+ areas) plans all include Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. The Asia (20 areas) /Day plan expands coverage to Laos, and the Global139 plan adds Brunei. Plans that target other regions such as Asia (12 areas) /Day list no additional Southeast Asian countries beyond those already mentioned; no plans cover Myanmar or Timor‑Leste.
