AlpineSIM does not provide any truly unlimited high‑speed data plans for Southeast Asia. All of the eSIMs listed for Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam and the additional countries in the 20‑area list include a specific data allowance, such as 500 MB per day, 1 GB per day, 2 GB per day, or larger, and after that limit the speed is throttled. The “Unlimited” label in the plan names refers to the fact that the data cap is fixed and the plan covers the designated area, not that it offers unrestricted data usage.
Travelers who need more data can instead choose from AlpineSIM’s fixed‑data plans. For example, the AlpineSIM Asia (7 areas) eSIM offers 20 GB for 30 days at $27.96 and a 50 GB for 180 days option at $53.90. A comparable plan covering 20 areas provides 50 GB for 180 days at $106.61 or 20 GB for 30 days at $47.92. These high‑capacity plans remain valid for the stated number of days and provide 5G connectivity across the covered Southeast Asian destinations.
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.
AlpineSIM offers several eSIM plans that cover Southeast Asian countries. AlpineSIM Unlimited Asia (7 areas) eSIM includes Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam; AlpineSIM Unlimited Asia (20 areas) eSIM includes Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, Vietnam; AlpineSIM Unlimited Singapore & Malaysia & Vietnam & Thailand & Indonesia eSIM includes Indonesia, Malaysia, Singapore, Thailand, Vietnam; AlpineSIM Unlimited Asia (12 areas) eSIM includes Indonesia, Cambodia, Malaysia, Singapore, Thailand, Vietnam.
