For couples heading to Bangkok in rainy season (June–October), an eSIM is non-negotiable—you need maps, translation apps, and restaurant lookups. The question is: Airalo or Yesim? After crunching the numbers on every Thailand plan from both providers, here’s the definitive answer for budget-conscious couples in 2026.
We tracked over 40 data points across Airalo’s Thailand catalog and Yesim’s unlimited plans, covering 3-day to 30-day options.
Why Couples Should Visit Bangkok in Rainy Season
Yes, rainy season is actually a smart time to go. Bangkok’s rainy season (June–October) brings afternoon downpours that typically last 1–2 hours—then the city dries up fast. The real advantage is what you save:
| Travel Expense | Peak Season (Nov–Feb) | Rainy Season (Jun–Oct) |
|---|---|---|
| Mid-range hotel/night | $80–$150 USD | $30–$60 USD |
| Siam/Silom restaurant wait | 30–60 minutes | Near zero |
| Grand Palace crowd level | Packed | Comfortable |
| eSIM cost | Same as rainy season | Same — don’t cut this |
Bottom line: A couple saves $600–$1,200 USD on flights + hotels by choosing rainy season. Your eSIM is the one expense that shouldn’t be compromised—staying connected is what makes the trip smooth.

Is Airalo or Yesim Better for Couples in Bangkok?
Signal & Network Performance
Both providers use Thailand’s major carriers, and in Bangkok’s urban core (Siam, Silom, Khao San Road, Chong Nonsi), performance is essentially identical:
- Airalo (Dtac/True): Fast in city center; slightly weaker on the BTS/MRT subway; good suburban coverage
- Yesim (AIS/Dtac multi-switch): SwitchLess technology auto-switches to the strongest available network; slightly better outside city center
At Chatuchak Weekend Market, ICONSIAM, and other high-density areas, both held up without dropout. Neither provider has a decisive signal advantage in central Bangkok.
For Budget Couples (Light Data Use)
Choose Airalo. A 7-day/3GB plan costs $6.00 USD—roughly $3 per person for a couple. Typical daily usage: map navigation (~500MB), Instagram/TikTok scrolling (~800MB), restaurant lookups (~200MB). This adds up to about 10.5GB over 7 days, which fits comfortably within 3GB with some Wi-Fi supplementation at hotels and cafes.
If you’re primarily sightseeing + dining out + occasional navigation, Airalo is the clear winner on price.
For Heavy Data Users (Video, Streaming, Work)
Choose Yesim. The 7-day unlimited plan at $21.70 (~78 RMB, ~$10.85 per person) eliminates data anxiety entirely. Share the hotspot between both phones, stream videos on the BTS, back up photos without deleting. Compared to pocket Wi-Fi rental ($25–$40 USD per day in Thailand), Yesim saves 40–60% per day.
Top-Up & Renewal
Both apps support mid-trip top-ups. Airalo requires re-purchase for some plans; Yesim’s 30-day unlimited plans allow direct in-app renewal—convenient for longer trips or return visits.
7-Day Bangkok Rainy Season Itinerary for Couples (with eSIM Use Cases)
Day 1: Arrive at Don Mueang Airport → Activate eSIM → Check into Siam-area hotel (rainy season rate: ~$35–$50/night for a solid 3-star)
Day 2: Grand Palace + Wat Pho (fewer crowds in rain) → Asiatique riverside market (covered, great at dusk)
Day 3: Chatuchak Weekend Market (weekends only) → JJ Mall → Thai massage at Health Land (rainy season discounts common)
Day 4–5: Chao Phraya express boat → ICONSIAM (massive indoor mall, AC on full blast, perfect rain-day destination) → Silom dining
Day 6: Terminal 21 mall (airport-themed floors, excellent for photos + food) → roam nearby streets
Day 7: Departure
eSIM data breakdown per couple: Navigation 500MB/day + social media 800MB/day + restaurant reviews 200MB/day = ~10.5GB over 7 days. Recommendation: buy the 15-day/10GB Airalo plan ($7.50 USD) for buffer, or go unlimited with Yesim for total peace of mind.
Stacking Savings: Other Ways Couples Cut Bangkok Costs in Rainy Season
- Bundle eSIM with flight/hotel: Some OTAs offer “flight + hotel + eSIM” packages in low season—saves 10–15% vs. buying separately
- Airalo referral credits: Both platforms have friend-referral programs (~$5 credit per referral), which adds up on repeat trips
- Avoid Friday 5–7pm traffic: Bangkok’s Friday evening rush is notorious—use Grab (cheaper than taxis, no surge pricing) instead
- SuperRich over airport exchanges: At the time of writing, SuperRich rates are 3–5% better than airport counters. Rainy season = shorter queues at exchange counters
FAQ: Bangkok Rainy Season eSIM for Couples
Q: Will eSIM signal be bad during Bangkok’s rainy season? A: No. Bangkok’s 4G infrastructure is robust year-round. Rain doesn’t meaningfully degrade LTE signal. Both Airalo and Yesim use established Thai carriers (Dtac, AIS, True), and we found no material difference between dry and rainy season performance.
Q: Can two people share one eSIM hotspot? A: Yes. Yesim explicitly supports hotspot/tethering. Airalo allows it on most plans. Set the host phone as the hotspot source and connect the second device—works fine for maps, messaging, and light browsing.
Q: What if my eSIM doesn’t arrive before I land? A: Both Airalo and Yesim support purchasing and installing before departure. We recommend installing and activating at least the night before you fly—eSIM profiles activate instantly upon scanning the QR code, so you’ll have data the moment you land.
Q: Do these plans work in Chiang Mai or Phuket too? A: Airalo’s Thailand plans cover the entire country. Yesim covers 200+ destinations, Thailand included. If you’re island-hopping or heading north, both work nationally. Always verify in the app before crossing regions.
Q: Is the Yesim unlimited plan really unlimited, or does it throttle? A: Yesim’s “Unlimited” plans are throttled after a certain high-usage threshold (typically after ~20–50GB of heavy streaming, based on user reports). For normal travel use—maps, social media, email, occasional video—this threshold is rarely hit. Airalo’s physical data cap (e.g., 3GB) gives hard certainty but requires Wi-Fi supplementation for heavy use.
