HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall for Bangkok, with App 5.0 and Support 5.0 on an iOS and Android app, live chat plus WhatsApp, and a 180-day refund. Plans price from $3.50/GB, far above Bangkok's own $0.29/GB local floor, with unlimited from $5, the widest gap of any destination in this comparison.
Dimension scores, 0-5 on our rubric
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- iOS and Android app with in-app top-up, add-destination, and usage alerts
- Live chat, WhatsApp, and email support, including real-time channels
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Newer brand (launched August 2025) with shorter track record
- 186 countries, behind Airalo's 200+ catalogue
Airalo -- Widest Coverage Catalogue
Airalo is the matrix default for Bangkok, routing over AIS and DTAC's 5G networks and True Move's 4G tier, with pricing from $3.49 for 1GB down to $0.29/GB at the 20GB tier, the cheapest local floor in this ten-city comparison. Airalo's own general rate card runs $4.50/GB, more than 15 times Bangkok's local floor.
Dimension scores, 0-5 on our rubric
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- No live chat or WhatsApp channel: support runs on email and in-app messaging
Nomad -- Best Budget Per-GB Rate
Nomad's general $3.00/GB rate still sits well above Bangkok's own $0.29/GB local floor. Nomad has no regional bundle for Thailand. Nomad's own pricing examples put a Thailand 5GB plan at $6.99, matching this matrix's Airalo-routed 5GB tier for Bangkok exactly, a rare case where a competitor's stated price lines up with the destination-specific ladder.
Dimension scores, 0-5 on our rubric
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with no live chat, WhatsApp, or phone channel
- Basic app compared to Airalo and Saily
- 200 countries, behind only Airalo among the five providers
- Limited plan variety in some countries
Holafly -- Best Unlimited Daily Rate
Holafly's $2.99/day unlimited rate undercuts Bangkok's own $3.49/day unlimited floor by $0.50. HelloRoam also sells unlimited from $5. The Holafly 1GB/day hotspot cap matters more for a traveler tethering a laptop from a Sukhumvit hotel than for one who streams straight to a phone.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 180-day refund policy on unused plans
- 24/7 chat support alongside email
Cons
- Speeds reduce after the daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Saily -- Best for Privacy
Saily bundles NordVPN into every Bangkok plan at $3.99/GB, well above Bangkok's own $0.29/GB local floor. Saily has no regional bundle for Thailand. Thailand's VPN access is unrestricted for general use, though the government's gambling and lese-majeste content blocks apply at the ISP level regardless of which VPN a traveler runs.
Dimension scores, 0-5 on our rubric
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 200 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 200 countries, just behind Airalo's 200-plus

FAQ
Bangkok eSIM questions, answered
Who leads the Bangkok eSIM comparison?
Who leads the Bangkok eSIM comparison?
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix. Airalo, Holafly, Saily, and Nomad follow on coverage breadth, daily unlimited, privacy, and per-GB pricing.
Which eSIM has the cheapest per-GB rate for Bangkok?
Which eSIM has the cheapest per-GB rate for Bangkok?
Bangkok's local per-GB floor sits at $0.29, the cheapest of any destination in this ten-city comparison. Every general provider rate card sits well above it, from Nomad's $3.00/GB to Airalo's $4.50/GB, though buying Airalo's destination-specific 20GB tier at $15.99 gets closest to that local floor. HelloRoam prices from $3.50/GB.
Does Bangkok have 5G coverage?
Does Bangkok have 5G coverage?
Yes. Bangkok is one of the handful of Thai cities, alongside Chiang Mai, Pattaya, and Phuket, where AIS and DTAC have switched on 5G. Rural provinces outside these areas remain on 4G only, a gap that applies to HelloRoam, Airalo, Holafly, Saily, and Nomad since network access does not depend on which eSIM a traveler buys.
Which Bangkok eSIM includes VPN protection?
Which Bangkok eSIM includes VPN protection?
Saily is the only provider in this matrix bundling NordVPN into every Bangkok plan. Thailand's VPN use is legal and widespread, though the government blocks some gambling and lese-majeste content at the ISP level, a restriction that applies regardless of which VPN is active.
