What can I still do in Vietnam after using up my 3GB high-speed data allowance?

3GB high-speed data ≈ 9.8 hours of 360p video or 2.7 hours of 720p HD video (estimated using YouTube’s recommended bitrates). Once exhausted, speeds will be reduced to 1 Mbps until your daily allowance resets:

  • Message WhatsApp, iMessage, Messenger
  • Email and Google Maps navigation
  • Voice calls via apps
  • Browse social media and watch 360p videos
  • Low-quality video calls
  • HD video streaming, large file downloads, and hotspot sharing with a laptop

7 days in Vietnam: Unlimited or data package?

Here, Unlimited is even cheaper than the 10GB plan (253,746 ₫ vs. 304,546 ₫) — it’s nearly certain to be the better value for your 7 days trip.

Using mobile data in Vietnam: local tips

  • 5G in cities, 4G beyond. Viettel, VinaPhone and MobiFone all run commercial 5G, and Viettel reports 5G in every province. Outside city centres, expect your phone to use 4G.
  • Ha Long Bay has dead zones. Limestone islands block signal in parts of the bay, and tour boats still lose coverage in some areas. Download tickets and maps before boarding.
  • Trekking in the far north. Almost every village now has mobile signal, but a few remote hamlets in the northern mountains still do not — carry offline maps on trekking and loop routes.
  • Zalo needs SMS verification. Many hotels and small businesses use Zalo. Signing up requires a code sent by SMS, so keep a SIM that can receive texts — this data-only eSIM has no number.
  • Paying by QR code. Visitors from China, South Korea, Singapore, Thailand, Laos and Cambodia can scan Vietnamese QR codes with some home banking or wallet apps.
  • Offline translation. Download Vietnamese in Google Translate before you travel so menus and signs can be translated where there is no signal.

FAQs about Vietnam eSIM

Everything you need to stay connected on your trip.

Unlimited data: your connection will never be cut off. However, high-speed data is limited to 3GB per day; once exhausted, speeds will be reduced until your daily allowance resets. Post-threshold speed in Vietnam: 1 Mbps.

Connects via Viettel, MobiFone, VinaPhone. Your device automatically selects the strongest available local carrier — no manual selection needed. 5G is available where the local carrier has deployed it; elsewhere, 4G applies.

At 1 Mbps these still work: Message WhatsApp, iMessage, Messenger, Email and Google Maps navigation, Voice calls via apps, Browse social media and watch 360p videos, Low-quality video calls. Not recommended: HD video streaming, large file downloads, and hotspot sharing with a laptop.

Unlimited (1GB/day high-speed data) starting at 27,508 ₫/day is enough for maps, messaging, and social media. Unlimited Plus (3GB/day) starting at 100,745 ₫/day is better if you frequently make video calls, post stories/videos, or share a hotspot with travel companions.

Yes. Note that hotspot usage counts toward your plan’s high-speed data allowance — a single laptop can quickly consume 1GB, and carriers may throttle speeds when hotspotting. For group sharing, we recommend Unlimited Plus or Premium.

The number of days starts when your eSIM first connects to mobile data at your destination — not from the purchase date. We recommend installing your eSIM before departure and only enabling it upon landing.

This plan routes traffic through an IP address located in HK. Some apps, streaming services, or websites may display region-specific content based on this location rather than your physical location.

Most iPhone XS+, Galaxy S20+, and Pixel 3+ models support eSIM. Your device must be unlocked.

No. This is a data-only plan; you’ll make calls and send messages via WhatsApp, iMessage, Messenger.

100% refund if the eSIM hasn’t been activated or if there’s a technical issue caused by us that we cannot resolve.
