About this tour
When Em from our team sorted a Vietnam SIM before heading to Ho Chi Minh City, this unlimited 5G plan made the whole trip run smoother. You pick between a physical card (grab it 24/7 at Tan Son Nhat Airport when you land) or an eSIM that arrives via WhatsApp or email before you leave home. Grab 10, 15, or 30 days depending on how long you're staying. High-speed data nationwide means maps work, Grab rides load instantly, and your mates back home can find you on messaging apps without drama.
Highlights
- 24/7 airport pickup means no waiting for a SIM hunt
- eSIM option arrives before you fly — connected from day one
- Truly unlimited data; no daily cap or throttling
- Works across Vietnam for navigation and ride-hailing
- Flexible duration options fit most trip lengths
- Officially registered with Vietnamese authorities
What to expect
Sorting this out is dead easy. If you're grabbing the physical SIM, you'll spot the pickup desk at Tan Son Nhat the moment you exit customs — no faffing about. If you've gone the eSIM route, you'll already have it loaded before takeoff, so your phone's ready the second you touch down. Coverage is solid everywhere we tested it: central Hanoi, rural Mekong villages, and the beaches around Nha Trang all pinged along without hiccups.
The actual experience is anticlimactic in the best way — you just use your phone normally. No daily limits means you can stream, map-read, and Grab without rationing data or checking your balance every ten minutes. Battery drain from 5G is noticeable if you're a heavy user, so a power bank is still worth throwing in your bag.

Good to know
Unlimited data is genuinely unlimited — no surprises when you hit some invisible threshold. The eSIM option is a lifesaver if you're the type who wants everything sorted before boarding. Physical SIM pickup at the airport beats hunting for a telco shop in a new city. Pricing is fair for what you get, and the plans are short enough that you're not committing to something longer than your stay.
You only get data — no local voice calls or SMS, so you'll need WhatsApp, Viber, or similar for calling home. If you need to ring Vietnamese numbers (restaurants, hotels, taxis), you'll have to rely on apps or ask your accommodation. 5G coverage is solid in cities and towns but patchier in very remote areas; 4G kicks in automatically, but it's slower. No travel SIM includes local calling minutes anyway, so that's a broader Vietnam phone thing rather than this service's fault. Practicals: Both options are straightforward to activate. The physical SIM arrives ready to go; the eSIM needs a quick QR scan. Works on any unlocked phone. Officially registered, so you won't hit any regulatory weirdness. No hidden fees beyond what you pay upfront.
