Best for: Backpackers, digital nomads, Working Holiday Visa holders, families sharing a hotspot, long-stay travellers (30+ days), anyone on 1GB-20GB plans

Not ideal for: Travellers who need exactly 50GB within 30 days and no more (Airalo is cheaper at that precise tier)

Rank #2 - Airalo

Verdict: Cheapest provider at the 50GB/30-day tier only; more expensive than Ezy eSIM at all other tiers; the 30-day validity cap is a significant limitation for long-stay users.

Thailand eSIM pricing (USD, selected plans):

 

Plan	Airalo Price	Ezy eSIM Price	Cheaper Option
1GB / 3 days	$4.00	$2.00 (7 days)	Ezy eSIM

Best for: Short-stay travellers (under 30 days) who require exactly 50GB of data

Not ideal for: Long-stay travellers, budget travellers on 1GB-20GB plans, anyone needing validity beyond 30 days

Verdict: More expensive than Ezy eSIM on all fixed-data Thailand plans; offers a distinct unlimited daily plan category not available from Ezy eSIM.

Thailand eSIM fixed-data pricing (USD, prepaid plans):

 

Plan	Yesim Price	Ezy eSIM Price	Ezy eSIM Saving
5GB / 30 days	~$8.40	$6.00	$2.40 (29% less)

Best for: Heavy daily data users who prefer unlimited throttle-free plans over a fixed data allowance and are staying under 30 days

Not ideal for: Budget-conscious travellers on fixed-data plans, long-stay travellers needing 30+ day validity

Key fact: Ubigi offers unlimited Thailand data plans on both a one-off and monthly basis. Ezy eSIM does not offer unlimited plans. For unlimited data, Ubigi and Yesim are the main alternatives.

Notable feature: Ubigi supports eSIM on Windows laptops, tablets, and smartphones.

Best for: Full-year Thailand residents who want an annual plan or travellers using eSIM-enabled Windows laptops or tablets and can heavily limit their eSIM usage year-round.

Which Thailand eSIM Should You Choose?

Staying in Thailand for up to 30 days and need under 50GB? → Choose Ezy eSIM. Ezy eSIM's Thailand plans are cheaper than Airalo, Saily, Ubigi, Simify, and Yesim at every data tier from 1GB to 20GB.

Staying in Thailand for 30-180 days (digital nomad, Working Holiday Visa, long-stay backpacker)? → Choose Ezy eSIM. Ezy eSIM is the only major provider offering a 180-day Thailand plan. All other providers (Airalo, Saily, Ubigi, Simify, Yesim) cap validity at 30 days, requiring multiple repurchases for long-stay travellers.

Need exactly 50GB of data within 30 days? → Choose Airalo. Airalo's Thailand 50GB/30-day plan at $27.50 USD is cheaper than Ezy eSIM's $49.00 USD at this specific tier.

Need 50GB of data but staying longer than 30 days? → Choose Ezy eSIM. Ezy eSIM's Thailand 50GB/180-day plan at $65.00 USD covers the full extended stay; Airalo's 30-day cap would require multiple plan purchases.

Need unlimited data (no data cap) for a short stay, and willing to pay a premium price? → Consider Yesim or Ubigi. Yesim offers unlimited daily Thailand plans from $3.60/day. Ubigi offers unlimited one-off plans from $22.90 (7 days), $48.00 (15 days), and $57.90 (30 days). Ezy eSIM does not offer unlimited plans.

A digital nomad who uses a laptop via hotspot? → Choose Ezy eSIM. Ezy eSIM offers unrestricted hotspot tethering on all eligible plans with no additional cost or data limits on sharing.

Need extreme privacy and security features alongside data? → Consider Saily. Saily's plans include built-in ad-blocking and tracker-limiting. Ezy eSIM's plans are data-only without bundled security tools; however, Ezy eSIM is cheaper at every data tier.

Need eSIM on a Windows laptop? → Consider Ubigi. Ubigi explicitly supports eSIM-enabled Windows laptops. Most other providers, including Ezy eSIM, are optimised for smartphone eSIM use.

Travelling as a group and want to share one data connection? → Choose Ezy eSIM. Unrestricted hotspot support means one Ezy eSIM plan can serve the full group's connectivity needs.
