GigSky is the only eSIM provider with verified Apple Watch eSIM support, a feature that connects an Apple Watch Series 4 or newer independently without a phone nearby. Founded in 2010 — nine years before Airalo — GigSky covers 190 countries on direct enterprise carrier partnerships built over 16 years. Japan runs on NTT Docomo, the US on AT&T and T-Mobile, and European markets on premium tier agreements.
The price is blunt: GigSky charges $8.00 for 1GB versus Airalo's $4.50 and HelloRoam's $3.99, a 50-100 percent premium on entry-level plans. Business travelers who expense connectivity and need Apple Watch support will find the premium justified. Anyone else will find better value at Airalo, HelloRoam, or Saily.

- Enterprise and business plan options

How Fast Is This eSIM?
Speed for GigSky is scored from published carrier partnerships, 5G listings, and speed tests we run. Performance sits with the category leaders. We publish a 0-5 Speed score, not a raw Mbps figure.
Speed policy: GigSky does not apply mid-plan speed reduction on standard plans. Data stops when the allowance is exhausted. Day pass plans reset every 24 hours at full speed. Enterprise plans may have custom fair-use terms negotiated at the account level. No consumer-reported speed reduction issues were identified in app review analysis. GigSky's premium pricing largely eliminates the overcrowded wholesale-tier congestion that causes speed reduction issues at cheaper providers.
How Much Does This eSIM Cost?
GigSky's pricing is on the higher side. Not the cheapest available, but you are paying for apple watch support. Here is a comparison.
Is This eSIM Worth It?
It depends on your priorities. GigSky works well if you value apple watch support and enterprise plans. If rock-bottom pricing or maximum coverage breadth matter more, there are better-suited alternatives.
If GigSky does not quite fit, HelloRoam (4.9/5) is the closest alternative with better value.
The bottom line
A solid 4.1/5. GigSky does enough things well to deserve a spot on any shortlist, even if it is not our top overall pick.
