If you need steady, unlimited mobile data for seven days in Vietnam, this short guide compares nearby unlimited eSIM options, explains activation and hotspot use, and recommends the simplest choice for city travel and day trips.
Quick summary
There aren’t many exact 7-day unlimited eSIMs listed, so the practical choices are a 5-day unlimited plan (cheaper) or a 10-day unlimited plan (covers a full week without topping up). For most travelers who want steady data for city logistics, bookings and day trips, the 10-day unlimited option is the simplest and lowest-risk pick.
What these unlimited eSIMs give you
- Networks: MobiFone and Viettel for broad coverage in cities and tourist areas.
- Connection: 5G/4G LTE speeds where available.
- Hotspot: Unlimited hotspot tethering on all listed unlimited plans.
- Activation window: eSIMs can be activated within 180 days of purchase—set it up just before you fly.
Why choose 10-day over 5-day for a 7-day trip
A 5-day unlimited plan can work if you split your trip or mostly rely on Wi‑Fi, but for continuous use (maps, rides, streaming, backups, bookings) a 10-day plan avoids the risk of running out midweek and the hassle of buying a second plan.

Activation and setup checklist
- Buy before travel and keep the QR code (instant delivery).
- Activate within 180 days—activate on arrival or during your last transit connection.
- Use the device’s eSIM settings: add plan, label it, set it as default for data and allow hotspot if needed.
- If you need voice or SMS, keep your home SIM for calls or use apps (WhatsApp/FaceTime) over data.

Final recommendation
For a one-week trip where you want worry-free, steady unlimited data and hotspot use, choose the 10-day unlimited eSIM (around $24.99–$29.99). If you want to save money and can tolerate limited downtime on two days, the 5-day unlimited option is an alternative.
