AlpineSIM eSIM Data Plans for Southeast Asia

AlpineSIM does not provide a truly unlimited data eSIM for Southeast Asia. All of its plans listed for the region specify a fixed data allowance, such as 500 MB/day, 1 GB/day, or larger flat caps. The plans that carry the word “Unlimited” in their name still contain these fixed limits and do not grant unlimited high‑speed data.

Travelers looking for higher data volumes can choose from AlpineSIM’s fixed‑data options. For example, the 20 GB plan is valid for 30 days and the 50 GB plan is valid for 180 days, both covering the same Southeast Asian countries. Selecting a fixed‑data plan can often be more cost‑effective unless a user expects to use a very large amount of data.

AlpineSIM does not provide a phone number or SMS capability on its eSIM plans for Southeast Asia. The provider offers only data‑only plans in this region, so no inbound or outbound voice or text services are included. To communicate while traveling, you can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.
