Roamify eSIM Data Plans for Southeast Asia

Yes, Roamify sells unlimited data eSIM plans for Southeast Asia. The plans cover Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam and are offered in 5G. Validity ranges from 1 day to 30 days, with prices starting at $3.00 USD for a 1‑day plan and going up to $70.00 USD for a 30‑day plan. Both the “Asia Sprint eSIM Unlimited Data” and “Southeast Asia eSIM Unlimited Data” collections are marked as unlimited and include tethering and a note that speeds may be throttled.

Although the data allowance is unlimited, Roamify applies a Fair Usage Policy that can reduce speeds after heavy usage. Plans explicitly state that speed may be throttled, so travelers who are concerned about potential speed restrictions should contact Roamify to confirm the extent of the policy and how much data remains at normal speed.

Roamify provides eSIM plans that include a phone number and SMS for travelers in Southeast Asia. The plans start at $15.00 USD for a 1 GB data allowance valid for 7 days, and can go up to $105.00 USD for a 20 GB data allowance valid for 365 days. The phone numbers are delivered with a dialing code of +1 for most Global Premium plans and +33 for the Asia Sprint and Southeast Asia eSIM options. Both inbound and outbound voice calls are supported, and inbound and outbound SMS are available as well. Travelers who need specific calling or messaging features are encouraged to confirm the details directly with Roamify.

Roamify offers several eSIM plans that provide coverage across multiple Southeast Asian nations. The Asia Sprint eSIM and Southeast Asia eSIM cover Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. The Asia One Year eSIM adds Laos to that same list of countries. The Global eSIM mirrors the Southeast Asia coverage. The Global Premium eSIM extends service to Brunei and Timor‑Leste, in addition to covering Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. All of these plans also include coverage outside Southeast Asia, but the countries listed above represent the regional coverage available under each plan.
