Bottom Line Up Front
For a 7-day couple trip to Ho Chi Minh City in the off-season, Airalo’s 5GB/30-day plan at $10 is the best value when you share a hotspot between two people. If you each need your own connection with unlimited data, Yesim’s daily unlimited plan at $1.99/day is the stress-free pick.
Why the Off-Season is Actually Better
May through October is Ho Chi Minh City’s rainy season — which means cheaper flights, half-price hotels, zero queues at tourist spots, and surprisingly pleasant weather. The downpours last 20-30 minutes, then clear up completely. For couples who don’t need perfect sunshine for beach photos, this is the smart move.
The one thing you absolutely cannot skip: sorting out your mobile data before you land.

Three Budget Scenarios for Couples
Plan A: Ultra-Budget (Airalo, separate 1GB each)
- Cost: $4.50 × 2 = $9.00 (~¥65)
- Data: 1GB per person — enough for Maps, WhatsApp, and Grab
- Best for: Couples staying at hotels with free WiFi, using data only for navigation and messaging
This works because off-season hotels in District 1 almost all include WiFi. You use your phones for navigation and translation during the day, and everything else happens on hotel WiFi at night.
Plan B: Smart Sharing (Airalo, one 5GB plan + hotspot) ⭐ Recommended
- Cost: $10.00 (~¥72)
- Data: 5GB shared between two people
- Best for: Couples who stick together and want to share Instagram stories, check reviews, and book Grab rides
For just $1 more than Plan A, you get 2.5x the data. Since you’re traveling as a couple, one hotspot connection covers both of you 90% of the time. This is the sweet spot between cost and convenience.
Plan C: Unlimited Convenience (Yesim, per-day activation)
- Cost: $1.99/day × 7 days × 2 people = $27.86 (~¥201)
- Data: Unlimited (throttled to 1Mbps after fair use)
- Best for: Content creators, social media-heavy travelers, or anyone who hates thinking about data caps
The 1Mbps throttle is fine for messaging, Maps, and light social media. You won’t be streaming Netflix, but you didn’t come to Ho Chi Minh City for that. If you’re posting to TikTok or Xiaohongshu daily, this is worth the peace of mind.
What About Saily?
Saily (by NordVPN) is a solid third option. Their pricing is competitive with Airalo ($3.99–$179.99 range), and they offer unlimited plans in select destinations. The main advantage is if you already use NordVPN — you can manage everything in one ecosystem. For Vietnam specifically, Airalo edges ahead on plan variety and established partnerships with local carriers.
FAQ
Do I need to install the eSIM before my trip?
Absolutely. Download and install the eSIM profile while you’re on WiFi at home. Once installed, it activates automatically when your phone connects to a Vietnamese carrier. Trying to install at Tan Son Nhat Airport without reliable WiFi is asking for trouble.
eSIM vs. buying a local SIM at the airport?
eSIM wins every time. No haggling with street vendors, no worrying about passport photocopies, no tiny SIM card trays to lose. The only catch: your phone needs to support eSIM (iPhone XS or newer, most recent Android flagships). If you’re carrying an older phone, you’ll need to buy a physical SIM.
Will hotspot sharing be slow with two people?
Not for normal use. Two people browsing Maps, WhatsApp, and Instagram simultaneously works fine on a 4G connection. If one person tries to download a large app while the other streams video, you’ll notice lag — but in Ho Chi Minh City, nearly every café offers free WiFi anyway.
Airalo (Vinaphone) vs Yesim (Viettel) — is there a signal difference?
In central Ho Chi Minh City (Districts 1, 3, and Binh Thanh), both networks deliver solid 4G. Viettel has slightly better coverage if you’re venturing to the Cu Chi Tunnels or Mekong Delta, but the difference is marginal for most tourists. You won’t notice it in daily use.
Can I get a refund if I pick the wrong plan?
Both Airalo and Yesim offer refunds for unused eSIMs. Once you scan the QR code and install the profile, the plan is non-refundable. So choose carefully and install only when you’re ready.
