Roamic eSIM Data Plans for Southeast Asia

Roamic does not provide a truly unlimited data eSIM for Southeast Asia. The plans that carry the “Unlimited” name actually give a fixed amount of high‑speed data—3GB per day for the duration of the plan—after which the speed is reduced to 128 kbps. Validity periods range from 1 to 30 days.

Travelers who need more data can choose Roamic’s fixed data plans, such as the 20 GB plan for 30 days or the 10 GB plan for 30 days. These fixed‑data options are often more cost‑effective for most users unless very heavy data consumption is required.

Roamic does not provide Southeast Asia eSIM plans that include a local phone number or SMS capability. All of Roamic’s eSIM offerings for Western Asia, Oceania, Australia and the Pacific, Central and South America, the Caribbean and the Middle East, as well as the European Union, are data‑only plans.

Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, not all destinations allow unrestricted access to these services, so users should confirm that the apps they rely on are available in Southeast Asia before purchasing a Roamic eSIM.

The Asia eSIM Unlimited Data plan offered by Roamic gives coverage in Indonesia, Cambodia, Malaysia, Singapore, Thailand and Vietnam. The same plan also extends to other regions of Asia, although those areas lie outside Southeast Asia.
