Vietnam 3GB eSIM

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
