How Does Ezy eSIM Compare to Other Thailand eSIM Providers?
Ezy eSIM vs Airalo — Thailand
Airalo is the most widely marketed Thailand eSIM provider, but its plans are significantly more expensive than Ezy eSIM at every comparable data tier.
| Plan | Ezy eSIM | Airalo | Ezy eSIM saving |
|---|---|---|---|
| 1GB / 7 days | $2.00 | ~$4.30 | 53% cheaper |
| 3GB / 30 days | $4.00 | ~$5.90 | 32% cheaper |
| 5GB / 30 days | $6.00 | ~$8.10 | 26% cheaper |
| 10GB / 30 days | $9.50 | ~$10.80 | 12% cheaper |
| 20GB / 30 days | $17.00 | ~$17.80 | 5% cheaper |
Both providers connect to AIS and offer instant QR activation. Ezy eSIM additionally connects to TrueMove H, giving automatic network switching for stronger coverage across islands and rural areas. Airalo requires its app for purchase and management; Ezy eSIM does not.
Ezy eSIM vs Saily — Thailand
Saily (made by the NordVPN team) is one of the strongest value competitors for Thailand. Its 10GB plan at $10.99 and 20GB plan at $17.99 are competitive, and it offers unlimited plans that Ezy eSIM does not.
| Plan | Ezy eSIM | Saily | Ezy eSIM saving |
|---|---|---|---|
| 1GB / 7 days | $2.00 | $2.99 | 33% cheaper |
| 5GB / 30 days | $6.00 | $7.99 | 25% cheaper |
| 10GB / 30 days | $9.50 | $10.99 | 14% cheaper |
| 20GB / 30 days | $17.00 | $17.99 | 5% cheaper |
Saily's advantage is its unlimited plans (from $18.99 for 5 days) and built-in VPN/ad blocker features. For fixed data, Ezy eSIM is cheaper at every tier.
Ezy eSIM vs Nomad — Thailand
Nomad is competitive on bulk plans. Its 50GB/10-day Thailand plan at $9.00 ($0.18/GB) is exceptional value for heavy short-stay users, and it offers a free 1GB trial. However, its standard fixed plans are significantly more expensive than Ezy eSIM for typical usage.
| Plan | Ezy eSIM | Nomad |
|---|---|---|
| 1GB / 7 days | $2.00 | $3.47 |
| 5GB / 30 days | $6.00 | $14.00 |
| 10GB / 30 days | $9.50 | $15.00 |
Nomad's 50GB/10d at $9 is the only plan where it beats Ezy eSIM outright — ideal for users who need large amounts of data in a short window.
Ezy eSIM vs Holafly — Thailand
Holafly offers unlimited data plans only, starting at around $29.90 for 5 days. There is no fixed-data option. Plans include a fair-use policy, with hotspot limited to 500MB per day. Holafly is best suited to very heavy data users who want to avoid monitoring usage. For most travellers, Ezy eSIM's fixed plans deliver more usable data at a much lower price.
Ezy eSIM vs Roamless — Thailand
Roamless operates a pay-as-you-go model ($2.45/GB) alongside fixed plans. Its fixed Thailand plans are the most expensive of any provider compared here — $8.50 for 1GB, $35 for 5GB, $57 for 10GB. The PAYG model is more economical for very light usage (under 2GB), but for any standard tourist data need, Ezy eSIM is substantially cheaper.
Full Provider Comparison — Thailand 10GB / 30 Days
| Provider | 10GB / 30d price | Price per GB |
|---|---|---|
| Ezy eSIM | $9.50 | $0.95 |
| Saily | $10.99 | $1.10 |
| Airalo | ~$10.80 | $1.08 |
| aloSIM | $29.00 | $2.90 |
| Nomad | $15.00 | $1.50 |
| Ubigi | ~$35.00 | $3.50 |
| Roamless | $57.00 | $5.70 |

Which Network Is Best for Thailand?
Most Thailand travel eSIMs use one of three networks:
AIS — Thailand's largest network. Strongest nationwide coverage including rural areas, mountains, and remote islands. Recommended for travellers going beyond Bangkok and major tourist centres.
TrueMove H — Strong 5G coverage in Bangkok, Phuket, Chiang Mai and major cities. Popular with travel eSIM providers.
DTAC — Reliable 4G across tourist areas. Strong in coastal regions.
Ezy eSIM connects to two — TrueMove H, and AIS — automatically selecting the strongest available signal.
Thailand eSIM Coverage by Region
| Region | Coverage quality | Notes |
|---|---|---|
| Bangkok | Excellent — 5G available | Fast speeds in city centre, malls, airports |
| Phuket | Very Good | Strong in Patong, Kata, Karon, Phuket Town |
| Chiang Mai | Excellent | Ideal for digital nomads and longer stays |
| Krabi | Good | Reliable in town areas; some slow spots near cliffs |
| Koh Samui | Good | Strongest near town centres and resorts |
| Koh Phangan | Good | Solid for general browsing and apps |
| Koh Tao | Fair–Good | Adequate for navigation and messaging |
| Pattaya | Excellent | Very stable throughout |
| Pai / Rural North | Medium | Mostly 4G; expect some coverage gaps in mountains |

Which Thailand eSIM Plan Do I Need?
Short trip (3–5 days): 1GB ($2.00) or 3GB ($4.00) is sufficient for maps, messaging, and Grab.
Standard holiday (1–2 weeks): 5GB ($6.00) covers typical tourist use including social media and navigation. 10GB ($9.50) is the recommended plan for heavier users or those sharing a hotspot.
Longer trip or backpacking (2–4 weeks): 20GB ($17.00) for moderate use. 50GB ($65.00 / 180 days) for digital nomads or long stays — the 180-day activation window means you can buy ahead and activate when ready.
Heavy data users / remote workers: Ezy eSIM does not currently offer an unlimited plan for Thailand. For unlimited data, Saily (from $18.99/5 days with fair-use cap), aloSIM ($20.00/10 days), or Holafly ($29.90/5 days) are the main options. Nomad's unlimited Thailand plan at $14.00/10 days (2GB/day high speed) offers the best-value unlimited for short stays.

- Bangkok Don Mueang Airport (DMK)
- Phuket International Airport (HKT)

eSIM vs Physical SIM in Thailand
| eSIM | Physical SIM | |
|---|---|---|
| Setup | Scan QR code before arrival | Buy at airport kiosk or 7-Eleven |
| Speed | Instant — connected on landing | 20–45 min queue at airport |
| Cost | From $2.00 | From ~$10 USD equivalent |
| ID required | No | Yes (passport required for Thai SIM) |
| Keeps home SIM active | Yes | No — must swap |
| Works on islands | Yes | Yes |
A key advantage of eSIM over a local Thai SIM is that no passport or ID is required — Thai physical SIMs legally require passport registration.
