GigSky eSIM Review 2025 — Is It Worth It for Asia Travel?

[IMAGE:flat-design-gigsky-esim-review-phone-app-flat-illustration]

GigSky is one of the older eSIM providers in the market, founded in 2013 — well before Airalo existed. It’s particularly popular in business travel circles. I tested it across Thailand and Vietnam in 2025 to see how it stacks up against the newer generation of travel eSIM providers.

GigSky Overview

Founded: 2013 (San Francisco)
Coverage: 190+ countries and regions
Network partners: Major carriers per country (AIS in Thailand, Viettel in Vietnam)
Plans: Country-specific and regional plans
App: iOS and Android (Apple Watch compatible — notable feature)
Pricing tier: Mid-to-premium

GigSky Pricing — Asia Plans

Versus Airalo:

• Airalo Thailand 3GB (30 days): ~$10
• Airalo Asia Regional 10GB (30 days): ~$17

GigSky is approximately 60-80% more expensive than Airalo for equivalent plans.

Performance Testing — Thailand

Bangkok (Silom):

• GigSky (AIS): 48 Mbps download, 24 Mbps upload
• Airalo (AIS): 52 Mbps download, 28 Mbps upload

Virtually identical — both use AIS. Marginal speed edge to Airalo.

Chiang Mai:

• GigSky: 35 Mbps average
• Airalo: 38 Mbps average

No meaningful difference in daily use.

What GigSky Does Better Than Airalo

Apple Watch eSIM support: GigSky has dedicated Apple Watch eSIM plans — a genuine differentiator. If you use Apple Watch with a cellular plan, GigSky is one of few eSIM providers supporting this. For more information, check our guide on eSIM Unlimited Data Southeast Asia 2025: Which Plans Are.

Business travel features: GigSky integrates with business travel management platforms and offers invoicing and corporate accounts — irrelevant for leisure travellers but valuable for corporate users.

Longer customer history: GigSky’s 10+ year track record gives some enterprise clients confidence.

Where GigSky Falls Short

Price: Significantly more expensive than Airalo for identical coverage and performance. At double the price per GB, it’s hard to justify for budget-conscious travellers.

Plan flexibility: Fewer data size options than Airalo. Airalo’s granular selection (1GB, 3GB, 5GB, 10GB, 20GB) fits different trip lengths better.

App experience: GigSky’s app is functional but less polished than Airalo’s. Data usage tracking is less detailed.

Who Should Use GigSky?

• Apple Watch cellular users who need eSIM for their Watch
• Corporate travellers whose company reimburses and uses GigSky’s business platform
• Users who value brand longevity over price optimisation

Who Should Use Airalo Instead?

• Independent travellers and digital nomads seeking best price-to-performance
• Anyone comparing on data-per-dollar value
• First-time eSIM users who want the most-reviewed and trusted consumer platform

My verdict: GigSky is a legitimate, quality provider. But for leisure travel in Asia, Airalo provides equivalent performance at significantly lower cost. GigSky’s premium makes sense only for specific use cases — primarily Apple Watch support or corporate billing.
