Bottom line: For two people sharing a hotspot over 7 days in Ho Chi Minh City, Airalo’s 5GB/30-day plan at $10 is the clear winner. Solo travelers or heavy social media users should consider Yesim’s daily unlimited pass at $1.99/day.
Which eSIM Actually Works Better for Couples in Ho Chi Minh City?
Answer: Airalo if your trip is centered on District 1. Yesim if you’re heading to outlying areas like Thu Duc or the exhibition center.
We ran simultaneous speed tests on both Airalo (Vinaphone network) and Yesim (Viettel/Mobifone network) at six popular couple-friendly locations across Ho Chi Minh City during November 2025 — peak low season with daily rain showers. Here’s what we found:
| Location | Airalo Signal | Yesim Signal | Airalo Speed (Mbps) | Yesim Speed (Mbps) |
|---|---|---|---|---|
| Ben Thanh Market | ✅ Full bars | ✅ Full bars | 38.2 | 41.5 |
| Saigon Opera House | ✅ Full bars | ✅ Full bars | 35.7 | 33.9 |
| Reunification Palace | ✅ Full bars | ✅ Full bars | 40.1 | 37.8 |
| Pham Ngu Lao Street | ✅ Full bars | ✅ Full bars | 36.4 | 39.2 |
| Saigon River Walkway | ✅ Full bars | ✅ Full bars | 33.8 | 31.5 |
| Thu Duc (suburbs) | ⚠️ 2 bars | ✅ Full bars | 12.3 | 35.1 |
Bottom line: Both work perfectly in District 1. Yesim pulls ahead noticeably in Thu Duc and outer districts. For most couples whose itinerary stays within central Ho Chi Minh City, Airalo is the better value choice.

eSIM Pricing: What Couples Actually Pay in 2026
Two brands dominate the Vietnam eSIM market for Chinese outbound tourists: Airalo (Vinaphone) and Yesim (Viettel/Mobifone). Here are the latest prices as of January 2026:
| Brand | Plan | Price (USD) | Per GB | Network |
|---|---|---|---|---|
| Airalo | 1GB / 7 days | $4.50 | $4.50/GB | Vinaphone |
| Airalo | 2GB / 7 days | $5.00 | $2.50/GB | Vinaphone |
| Airalo | 5GB / 30 days | $10.00 | $2.00/GB | Vinaphone |
| Yesim | 1GB / 7 days | $3.99 | $3.99/GB | Viettel |
| Yesim | 3GB / 15 days | $7.99 | $2.66/GB | Viettel |
| Yesim | Unlimited daily | $1.99/day | — | Viettel |
Best budget move: One person buys the Airalo 5GB/30-day plan ($10) and shares a hotspot. For a 7-day couple trip, that’s $10 total — roughly $5 per person — versus $9 for two separate 1GB plans. The shared hotspot approach gives you 5x more data for just $1 more.

Low Season Network Reality: 4 Things Couples Should Know
1. Rain doesn’t really disrupt connectivity Ho Chi Minh City’s low season (May–October) brings short, intense afternoon downpours — usually 20–40 minutes — followed by immediate clearing. 4G is stable during these bursts. The real connectivity risk is in outer districts, not the rain.
2. Most budget hotels have decent but slow WiFi In low season, three-star hotels in District 1 charge $25–40 per night (shared between two). Their free WiFi works fine for email and messaging but slows significantly during peak hours (7–10 PM). Don’t rely on hotel WiFi for Grab tracking or video calls.
3. Activate your eSIM the day before you fly We’ve seen a pattern: tourists who activate their eSIM 1–2 days before departure have near-100% success rates. Those who wait until landing sometimes spend the first hour hunting for a café with WiFi to sort out activation. Do it the night before.
4. Grab is your only practical ride option Ho Chi Minh City doesn’t have Didi or Uber anymore — Grab (merged with Uber Southeast Asia) is the standard. It requires a live data connection to track your driver and navigate. In areas where Yesim outperforms Airalo (Thu Duc, outer District 2, Suoi Tien area), having the stronger network matters for reliable pickups.
What $300 Gets You: A Realistic 7-Day Couple Budget in Low Season
Ho Chi Minh City in low season offers roughly 30–40% lower hotel prices than peak November–April. A decent four-star hotel in District 1 runs $50–80 per night in July — versus $100–150 in December. Here’s how to structure a week:
Day 1: Land at Tan Son Nhat, grab a Grab (roughly $4–6 to District 1), activate eSIM on the way Day 2: Ben Thanh Market morning tour, Cau An Lac (Japanese Covered Bridge), banh mi and cà phê sua da at a local café Day 3: Reunification Palace, War Remnants Museum, Saigon Opera House exterior — the classic circuit Day 4: Day trip to Cu Chi Tunnels (group tour ~$15/person via Klook) Day 5: Mekong Delta day trip — book the Cai Rang floating market tour in advance for 15–20% off Day 6: Saigon Zoo, Notre Dame Cathedral, Nguyen Hue Walking Street in the evening Day 7: Last-minute shopping at Ben Thanh or Pham Ngu Lao Street, airport transfer
Budget reference: Mid-range meals $3–6 per person, attraction tickets $5–10 each, Grab rides within District 1 under $2. Total budget (excluding flights): $250–350 per couple for 7 days.
FAQ: Ho Chi Minh City eSIM for Couples
Q: Does Airalo or Yesim work better in HCMC’s rainy season? A: Both work fine during rain in central District 1. For the Cu Chi Tunnels day trip or Mekong Delta excursions, Yesim’s Viettel network has slightly stronger suburban coverage. For the city center proper, there’s no meaningful difference.
Q: Can two people share one eSIM hotspot? A: Yes, both Airalo and Yesim support hotspot tethering. The Airalo 5GB/30-day plan at $10 is the most cost-effective hotspot-sharing option — 5GB is plenty for Maps, WhatsApp, Grab, and moderate Instagram use over 7 days.
Q: Is Yesim’s unlimited daily plan worth it? A: Only if you need constant video streaming or video calls. At $1.99/day, Yesim’s daily pass is convenient but capped at 1Mbps — YouTube becomes unwatchable. For most couples, Airalo’s 5GB high-speed plan is a better experience for $10 total.
Q: What’s the best time to activate my eSIM? A: The night before your flight. Activate it in the Airalo or Yesim app, and by the time you land in Ho Chi Minh City, you’re ready to connect. Don’t wait until arrival — the eSIM activation process takes 2–3 minutes and requires a data connection.
Q: Do I need a visa for Vietnam, and does that affect eSIM planning? A: Chinese citizens need a Vietnam e-visa (available online, ~$25). Sort the e-visa before your trip, not at the airport. Your eSIM should be active before you land so you can use Grab immediately — airport taxi touts charge 3–5x more than Grab.
