The short answer
Vietnam is a short flight from Australia and a long trip on the ground, and a Telstra day charge adds up fast. I read Telstra's roaming page on 10 November 2026 and set its A$10 a day against the eSIMs I priced on 10 November 2026. For a few days I would buy Airalo at $11.50, and for two weeks or more Ringo Light.
Unlimited data at full speed for 2 weeks at $22.99 or 30 days at $42.99, nothing renews. Airalo asks $48 for 15 days and $69 for the month.
10 GB for 30 days at $13 on VNPT with 5G. Ubigi sells no unlimited plan for Vietnam.
Unlimited for 3 days at $11.50 on its Xin Chao plan, and buckets from $4 for 1 GB.
Days, not gigabytes, no daily cap stated for your own phone, on Vinaphone. $27.50 for a week; sharing limited to 1 GB a day.
Prices read on 10 November 2026: Airalo, Holafly, Saily, Nomad, Ubigi, Telstra, Ringo Light, European Central Bank on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

That is the full Ringo service: one plan that works everywhere, with your own number included.
It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to see in Vietnam, and what your phone needs for it
Eight places most trips to Vietnam include, from Hanoi in the north to Hoi An and Ho Chi Minh City. Whichever plan you pick, the tip under each one is where your phone matters.
Roam with Telstra, or buy an eSIM
On 10 November 2026 I read Telstra's International Roaming page, which puts Vietnam in Zone 2 at A$10 a day on the International Day Pass. A day is charged when the phone makes or receives a call, sends a text or uses data, background data included. At the ECB reference rate of 10 November 2026, A$1 = $0.69, that is about $7 for one day, A$30 (about $21) for three days of use, A$140 (about $97) for two weeks and A$300 (about $207) for 30 days. The page shows no monthly pass.
Ringo Light sells three trips for Vietnam, all unlimited: $8.99 for 7 days, $22.99 for 2 weeks and $42.99 for 30 days. Two weeks is about $97 on the Day Pass against $22.99, and a month is about $207 against $42.99.
For 3 days I would not pick Ringo Light, which sells no 3-day plan here. Airalo sells 3 days of unlimited at $11.50 against about $21 on the Day Pass, though Ringo Light's 7 days at $8.99 costs less than that. For a week Ringo Light asks $8.99, Airalo $27 and Holafly $27.50, against A$70 (about $48) of Day Pass days. Saily has 5 days at $18.99, against A$50 (about $35).
For two weeks or more Ringo Light is the cheapest unlimited. Airalo asks $48 for 15 days, Saily $48.99 and Holafly $51.50, and for a month the rivals run $69 to $76.50.
What Telstra wins is real. Your Australian number keeps ringing, calls and SMS are included, nothing needs installing, and a phone with no eSIM slot works. For a single day in Hanoi, about $7 beats every eSIM on this page.
Networks in Vietnam, and what the Day Pass gives you
Airalo, Holafly and Ubigi ride VNPT, also called Vinaphone. Nomad lists Vietnamobile, MobiFone and Vinaphone. Saily does not name its network, and Ringo Light uses a local partner network. Viettel, the largest network, is not named by any brand I priced, so I would test signal in the first city before a long train out of it.
The Day Pass includes 2 GB of data a day and unlimited standard calls and SMS, and unused data expires at the end of each day. Telstra's page states no roaming speed and no hotspot rule. On Upfront plans the pass runs for 24 hours from first use, and on other plans to 11:59pm AEST. Receiving an SMS does not start a day. Telstra sells a 2 GB top up at A$10 (about $7), valid for 31 days. Pre-Paid customers are sent to separate packs with no prices on the page, so I priced the Day Pass only.
The travel eSIMs are data only, with no Vietnamese number. Calls go over apps that use data.
If you want a data bucket: Ubigi
- Ubigi, $13 for 10 GB. The cheapest 10 GB for 30 days, on VNPT with 5G. Its 20 GB is a monthly plan that renews.
- Nomad, $17 for 10 GB. On Vietnamobile, MobiFone and Vinaphone, 20 GB for $25, and 50 GB for $39.
- Saily, $17.99 for 10 GB. 20 GB at $28.99.
- Airalo, $18 for 10 GB. Its Xin Chao plan rides VNPT. 20 GB for $29.
- ✓Telstra, a 2 GB top up for A$10. That is about $7 for 2 GB valid for 31 days, dear next to every bucket above, though nothing needs installing.
- ✓Ringo Light, no buckets. Its 2 weeks is unlimited for $22.99 and its 30 days unlimited for $42.99. For a fixed 10 GB, Ubigi at $13 is the better buy. I would buy Ringo Light for unlimited, not for a bucket.
What Ringo Light is
Ringo Light is Ringo's own data eSIM, and I write for Ringo, so weigh that. It is data only: no number, no calls, no texts. It sits beside your own SIM, so your Telstra number keeps working for calls and texts. For Vietnam it sells three trips, all unlimited data at full speed: 7 days at $8.99, 2 weeks at $22.99 and 30 days at $42.99. Nothing renews. One payment, and the eSIM arrives by email as a QR code in seconds and installs in one scan, no app.
Telstra charges a day whenever the phone is used, so I would switch Telstra roaming off while the eSIM carries the data and switch it on only for a call I need.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Telstra Day Pass. A single A$10 day, about $7, nothing to install.
Airalo unlimited, 3 days, $11.50, against about $21 on the Day Pass. Ringo Light sells no 3 days.
Ringo Light unlimited, 2 weeks, $22.99, against about $97 on the Day Pass.
Ringo Light unlimited, 30 days, $42.99, against about $207 on the Day Pass. Nomad 50 GB at $39 if you know you will use a lot.
Ubigi 10 GB for 30 days at $13.
Keep your Telstra SIM in beside the eSIM. The Day Pass carries calls and SMS on your number and the travel eSIMs do not; the full Ringo, which Ringo Light funds, ports the number you have.

We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.

Left out: Maya Mobile. We could not read its own prices for this country on the day, so it stays out rather than being guessed.
