Choose plan: Singapore & Malaysia & Vietnam & Thailand & Indonesia Unlimited eSIMCheck coverage, activation timing, hotspot rules and the final price on the selected product before paying. These travel eSIMs are data-only, with no local phone number, standard calls or SMS.
Coverage across Southeast Asia
The eSIM connects through supported partner networks in each included country. Speed and signal depend on the local network, device and location, and can vary between cities, islands, rural districts and border regions.
Will my phone work in Southeast Asia?
Your phone can use a travel eSIM in Southeast Asia if it supports eSIM and is carrier-unlocked. Check for an “Add eSIM” option or an EID in your phone settings. Your Australian SIM can stay in the phone: with dual SIM it may remain available for calls and texts (your own carrier’s roaming charges apply), while the travel eSIM is used for mobile data. Check phone compatibility.
Southeast Asia eSIM questions
Will the eSIM reconnect after crossing a border?
It should connect to a supported local partner network in an included country. If it does not connect promptly, restart the phone and follow the network-selection instructions supplied with the plan.
Can I use the same QR code on several phones?
No. An eSIM profile is normally installed on one compatible device only, so purchase one profile for each phone that needs its own connection.
Short answer: sizing a plan for 1–2 weeks
Best fit by data per day for most Australians visiting Southeast Asia for a week: 1GB a day for 7 days, $23.90 AUD, with a set high-speed allowance each day. It is data-only: no local phone number, standard calls or SMS.
| Plan | Price | Data per day | Who it suits |
|---|---|---|---|
| 1GB/day · 7 days | $23.90 AUD | 1GB high-speed | A set high-speed allowance every day; speed is reduced after it is used |
| 1GB/day · 30 days | $99.90 AUD | 1GB high-speed | A set high-speed allowance every day; speed is reduced after it is used |
Data per day is the plan’s data divided by the trip length (up to 14 days): a planning average, not a daily allowance or a guarantee it will cover your use.
Is a regional eSIM right for your trip?
A Southeast Asia regional eSIM can keep a compatible, unlocked phone connected across several popular destinations without installing a new plan at every border. The current regional option covers Singapore, Malaysia, Vietnam, Thailand and Indonesia; confirm the included-country list on the product page before buying.
A regional plan is convenient for a multi-country itinerary. For a single-country holiday, compare it with the dedicated destination plans because price, network and data conditions can differ.
Understanding daily unlimited-style data
Unlimited-style plans may include a daily high-speed allowance followed by reduced speeds under a fair-use policy. Check the product page for the daily allowance, reset time, hotspot conditions and validity period.
Using your Australian number
Most travel eSIMs are data-only. A compatible dual-SIM phone can usually keep the Australian SIM installed for calls and messages while the regional eSIM handles data. Disable data roaming on the Australian line if you want to avoid carrier roaming charges.
