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 on NTT Docomo, the US on AT&T and T-Mobile, and European markets on premium tier agreements all average 35-75 Mbps download speeds.
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.
