Use prepaid data on the phone you already carry. This is how PikoeSIM compares with a rental router, home-carrier roaming and a physical SIM.

Frequently asked questions.
Answers to common setup and buying questions.
How do I pick the right Vietnam plan?
Start with how many days you'll be away, then estimate your data use among these data plans. The 100 MB and 500 MB options leave little room for photos or downloads. For lighter use, 3 GB for 15 days at €2.10 is a sensible middle ground; 10 GB for 30 days at €6.60 suits heavier sharing. Even a one day visit forces buying at least a 7-day plan because there is no 1 day card in the list. The best value isn't always the best price, since a plan you underuse costs more per gigabyte. Our recommendations match allowance to trip length rather than chasing the cheapest card or assuming the biggest plan has the best coverage. Compare options online before you buy.
Which network and speeds does it use?
Vinaphone Vietnam is the listed network, with 4G/LTE and 5G support. Your phone and local coverage decide which technology you get, and signal quality can drop indoors, between towns and on mountain routes.
Is my phone compatible with this eSIM?
Check that your exact model and regional variant support eSIM and that the device is network unlocked. On an iPhone running iOS, open Settings, General, About and check Carrier Lock; No SIM restrictions means it's unlocked. On Android, follow the manufacturer's compatibility guide for a full list of compatible phones before you buy. A virtual SIM card won't install on phones without eSIM support.
When should I install and activate it?
Install over dependable Wi-Fi and keep the instructions offline. Follow the supplied activation steps before you enable the line, because installation and the start of validity are not necessarily the same event. Your order may use a QR code or app instructions, so follow whatever your plan provides. Don't count on instant installation; give yourself time before departure. On arrival, select the travel eSIM for mobile data and apply the roaming and APN settings it specifies.
Can I still use WhatsApp and receive bank codes?
Your existing messaging-app account works over the eSIM's internet connection. Standard SMS and bank verification codes still rely on your regular SIM, bank and carrier, and this data-only plan adds no local phone number. Check your home carrier's charges if that line stays switched on. Watching YouTube over mobile data will draw down your allowance quickly, so save that for Wi-Fi.
Can I tether a laptop to this eSIM?
The listed networks support hotspot. Any device you connect draws from the same data allowance. Tethering and the data hotspot features let connected devices draw from the same allowance. Automatic updates, video meetings and cloud backups on those devices can consume much of a fixed allowance, so pause them or switch to Wi-Fi when you can.
Is my data unlimited or renewed each day?
Each card shows one fixed total allowance for its validity period. It isn't unlimited and doesn't reset daily, and hotspot devices draw from the same pool. A longer validity doesn't add data, and there is no monthly subscription: 30 days is roughly one month but isn't a rolling calendar month. A trip of 14 days, or 2 weeks, fits the 15-day plan because no exact 14-day option exists, and the data remains one total allowance. The days and data are both fixed when you buy.
Does the plan work outside Vietnam?
No, these offers cover Vietnam only. Arrange separate coverage for onward destinations and check the exact country list on any regional plan. A connection near a border doesn't count as coverage in the neighbouring country.
Can I top up or extend my plan?
Choose a listed plan that covers the extra data and days you need and follow the instructions for that purchase. Don't assume it extends an existing plan, reuses its profile or carries over unused data. Keep the installed profile while you sort out any connection problem, and read the terms to confirm whether a no contract top up applies to your order.
What do I check when data won't connect?
Confirm you're in Vietnam, the eSIM is enabled and selected for mobile data, and the plan still has data and validity. Follow the supplied roaming and APN instructions, briefly toggle airplane mode or restart, then try another location. Keep the profile installed and have your phone model, location and order reference ready before requesting help.
How do I stop my home SIM using data?
Set the travel line for mobile data and turn off automatic data switching. Leave data roaming off on your regular SIM and apply any required travel-eSIM roaming setting only to the travel line. Calls and texts on your regular number still follow your home carrier's terms.
What should I check before asking for a refund?
Keep the order reference, installation details and a description of the fault. Refund eligibility depends on the purchase conditions and whether the plan was activated or used, so read the applicable policy before ordering. Don't delete an installed eSIM as your first troubleshooting step.
Do I need a separate eSIM for Hoi An?
No separate city eSIM card is needed. The same Vietnam plan works in Hanoi, Hoi An and Ho Chi Minh City wherever the listed network is available, within its remaining data and validity. Keep transfer details and hotel addresses offline between stops.
Using your Vietnam eSIM
A prepaid Vietnam eSIM for the trip ahead
Arriving in Hanoi, transferring from Da Nang to Hoi An, or filling a day in Ho Chi Minh City, an eSIM installs digitally on a compatible, unlocked phone so you can use mobile internet in Vietnam without swapping your physical SIM.
The 100 MB and 500 MB offers suit light use such as maps and short messages. For a short stay, weigh 1 GB for 7 days at €0.83 against 3 GB for 15 days at €2.10; the 1 GB card is the more affordable of the two if your use is light. There's no exact 14-day option, so a 2-week trip fits the 15-day plan.
For a longer trip, 10 GB for 30 days is €6.60. The 50 GB option runs for 180 days, but its data is still one total allowance rather than a monthly allowance that resets. There's no 1 day card in this list, so even a one-day visit means buying at least a 7-day plan. Compare days and data together before you buy.
Plan for the gaps between strong signals.
Vinaphone Vietnam is the listed network operator, with 4G/LTE and 5G support. The technology you actually get depends on your phone and local coverage, and signal quality can drop indoors, between towns and on mountain roads.
kept in reach.Hoi An, Vietnam
Hanoi: record more than the hotel name.
Noi Bai airport serves Hanoi, while the Old Quarter is a separate transfer into the city. Before you leave arrivals, open your booking and send the driver your hotel's full address, including any lane or entrance notes.
The Old Quarter's narrow streets make a precise meeting pin worth having. If your group splits up, agree on one landmark and a time, and keep a screenshot in case one phone drops its connection.
Maps and short messages use far less data than continuous video. Download a city map on Wi-Fi and save your next airport or rail booking offline before you change hotels.
Save before you goHotel address, pickup confirmation, an offline city map and your onward booking.
Hoi An: sort the transfer and the last stretch.
Da Nang's airport is the air gateway for Hoi An. Confirm the drop-off point with your accommodation and ask where a car can stop for the final walk to your room.
Vietnam Tourism recommends walking and cycling for the Ancient Town and the countryside. Pin your accommodation before you head towards the Japanese Bridge, and save the return point if you hire a bicycle.
A riverside photo is quick to send; a full day of cloud backups is not. Keep background uploads on Wi-Fi so your allowance stays free for the return transfer or a message to your host.
Save before you goAccommodation entrance, Da Nang transfer details and the bicycle return point if you need one.
Ho Chi Minh City: pin an exact pickup spot.
A day in the city may stretch between Ben Thanh Market and the historic centre. Save the specific entrance you'll use rather than one broad landmark pin, then share it with your companions.
Use data to check attraction details and confirm a booking's address before you cross the city. For a pickup, follow the location shown by your transport service and keep the vehicle details handy.
Set up any app account before you depend on it for the first ride. The eSIM provides internet but no local phone number or SMS, so a service asking for a verification code may still need your existing phone line.
Save before you goMeeting pin, accommodation address and screenshots of your activities and transport bookings.
