Daily data planning reference
Estimate by how you normally use your phone.
Indicative planning ranges only. Actual consumption varies materially with app settings, video quality, uploads, hotspot use, cloud sync and background activity.
Navigation, social feeds, travel apps and regular browsing.
Frequent social use, short-form video and travel apps throughout the day.
Built for the trip
Built for the itinerary, not one border.
For trips that keep moving, install once and use the same eSIM profile across supported countries and partner networks instead of repeating setup at every border.

Refunds at a glance
Know the basics before you buy.
Refund eligibility depends mainly on whether the eSIM has been installed, activated or used, and whether a service problem can be resolved.
No eSIM email within 2 minutes? Full refund.
The 2-minute delivery guarantee starts after payment is confirmed. If the eSIM email is not delivered within that window, we refund the order in full.
Unused eSIM
May be refundable if it has not been installed, activated or used and the profile can still be cancelled.
Activated or used
Generally not automatically refundable once the eSIM has been installed, activated or used.
Service problem
If a verified provisioning or service failure cannot be resolved, a replacement, partial refund or full refund may be considered.
Good to know
Southeast Asia FAQs.
Is this an all-Asia plan?
No. The launch regional plan currently covers seven countries: Thailand, Singapore, Vietnam, Philippines, Indonesia, Malaysia and Cambodia.
Do I need to reinstall it at each border?
No. The goal of the regional product is to keep the same eSIM profile while moving between the included countries, using supported local partner networks.
Which countries are included in the Southeast Asia eSIM?
The current regional plan covers Thailand, Singapore, Vietnam, Philippines, Indonesia, Malaysia and Cambodia.
Can I use the regional eSIM for a one-country trip?
The Southeast Asia configurator is for multi-country trips with at least two selected destinations. For a one-country trip, use the relevant destination eSIM page instead.
Can I keep my physical SIM installed?
Yes. On a compatible unlocked dual-SIM/eSIM phone, your usual SIM can remain installed while Roamvaya is used for regional travel data.
Does the Southeast Asia eSIM include a phone number?
Roamvaya launch plans are data-first products unless a specific plan explicitly states otherwise. Internet calling and messaging apps can use the mobile data connection where those services are available.
How much data should I choose for a multi-country Southeast Asia trip?
Choose based on trip length and expected use. Light and More provide fixed total data, while the Recommended option provides a daily high-speed allowance with reduced-speed data after the daily allowance is used. Actual usage depends on video, hotspot, cloud backup and app behavior.
