The short answer
You hold a Vodafone contract and a ticket to Hanoi or Ho Chi Minh City, and the choice is whether to roam on a ReisePaket World or buy a travel eSIM first. I read what Vodafone charges for Vietnam on 10 November 2026 and set it against the eSIMs I priced on 10 November 2026 and Ringo Light. For a fortnight or a month I would buy Ringo Light and keep my own SIM in for calls and texts. For one or two days I would look at Airalo or a single World Tag.
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, Vodafone, 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 and Ha Long Bay to Hue, Hoi An and the Mekong Delta. Whichever plan you pick, the tip under each one is where your phone matters.
Roam with Vodafone, or buy an eSIM
Vodafone lists Vietnam among more than 100 non-EU countries in ReisePakete World, which I read on vodafone.de on 10 November 2026. World Tag is €9.99 (about $11) for a day with 500 MB and is charged only on days you use the phone abroad. World Woche is €34.99 (about $39) for a week with 4 GB. At the ECB reference rate of 10 November 2026, the latest published, 1 euro = $1.1214, three days of use come to €29.97 (about $34). Two weeks is two Woche passes, €69.98 (about $78). A month is four Woche passes and two Tag days, €159.94 (about $179), since the page shows no monthly pass for Vietnam.
Ringo Light is one payment per trip: $8.99 for 7 days, $22.99 for 2 weeks and $42.99 for 30 days, unlimited data at full speed. It sells no 3-day plan. Two weeks costs about $55 less than Vodafone, and a month about $136 less. A single Woche pass at about $39 costs more than Ringo Light's 7 days at $8.99, the same length, and more than its 2 weeks for twice the days.
Among the travel eSIMs, Ringo Light is also the cheapest unlimited for a week, two weeks and a month. Airalo asks $48 for 15 days, Saily $48.99 and Holafly $51.50. For a month the rivals run $69 to $76.50. For a week, Ringo Light asks $8.99, Saily $26.99, Airalo $27 and Holafly $27.50, so even a week is cheaper on an eSIM than a Woche pass. For three days, Airalo asks $11.50, about $22 under three Vodafone days, and Ringo Light sells no 3 days.
What Vodafone wins is real, and I do not wave it away. Your German number keeps ringing, with 50 minutes and 50 texts a day included to Germany or within Vietnam, nothing needs installing, a phone with no eSIM slot works, and the charge lands on a bill you already pay. For a night in transit through Hanoi, one World Tag at about $11 is the sensible buy.
Networks in Vietnam, and what a Vodafone pass includes
Vietnam has three big networks, Viettel, Vinaphone and MobiFone, and the cities and the main tourist routes have good 4G. The travel eSIMs I priced ride a smaller set. Airalo and Ubigi name VNPT, Holafly names Vinaphone, and Nomad names Vietnamobile, MobiFone and Vinaphone. Saily does not name its network. Ringo Light uses a local partner network. Viettel, the largest, is not named by any of the brands I priced. For Hanoi, Hoi An and Ho Chi Minh City I would not pick a plan on network.
The Vodafone pass has terms of its own. I read that you pay only on days you use your tariff abroad, and that German local time applies to the day. The page says the World Tag is added automatically in many tariffs, which I would check under Mein Tarif in MeinVodafone before the flight, or a day can appear on the bill that you did not plan. The passes are described as without contract commitment. The page names no speed once the data runs out, states no hotspot rule and does not say whether prepaid customers can use them, so I would ask Vodafone about each before leaning on it.
There is also WorldTravel, €4.99 a month (about $6) for 2 GB, with Vietnam on its list, but on a 12-month term of €59.88 (about $67) in all. I would not buy it for a single holiday. The travel eSIMs here are data only, with no Vietnamese number. Calls go over apps that use data, such as WhatsApp or FaceTime.
If you want a data bucket: Ubigi
- Ubigi, $13 for 10 GB. The cheapest 10 GB for 30 days, on VNPT with 5G. 10 GB is four times the 4 GB in a Vodafone Woche pass, for about a third of its price.
- Nomad, $17 for 10 GB. On Vietnamobile, MobiFone and Vinaphone, with 20 GB at $25 and 50 GB at $39 for a month of work online.
- Saily, $17.99 for 10 GB. 20 GB at $28.99.
- Airalo, $18 for 10 GB. Its Xin Chao plan rides VNPT, with 20 GB at $29.
- ✓Ringo Light, no buckets. Its 2 weeks is unlimited for $22.99 and its 30 days unlimited for $42.99. For 10 GB that must last a month, Ubigi at $13 is the better buy, and I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is Ringo's own data eSIM, and I write for Ringo, so weigh that. It is sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. 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. The eSIM arrives by email in seconds as a QR code and installs in one scan, no app. It is one payment, and the card shows the price in euros before you pay.
It is data only: no phone number, no calls, no texts. It sits next to your own Vodafone SIM, so your German number keeps working for calls and texts if you leave roaming on for those, and I would check how Vodafone bills the day before leaning on that.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
One Vodafone World Tag at €9.99, about $11. No purchase and nothing to install.
Airalo unlimited, 3 days, $11.50, against about $34 for three Vodafone days. Ringo Light sells no 3 days.
Ringo Light unlimited, 2 weeks, $22.99, against about $78 on Vodafone and $48 or more on a rival.
Ringo Light unlimited, 30 days, $42.99, against about $179 on Vodafone. Nomad 50 GB at $39 if you know you will use a lot.
Ubigi 10 GB for 30 days at $13.
Keep your Vodafone SIM in beside the eSIM. Vodafone carries calls and texts on your number and the travel eSIMs do not; the full Ringo, which Ringo Light funds, ports the number you have.
