It's good but a bit slow sometimes
I used GigSky in Canada for 10 days through the free 15-day, 3GB plan offered with my Visa Infinite card. Overall, the service was okay, so I would give it 4 stars. I really liked having the option to use an eSIM for free while traveling, and the activation and setup were fairly straightforward. However, I found the connection to be slow on many occasions, which was a bit frustrating, especially when I needed to use mobile data while out and about. The service is not bad at all, but I think it could be much better in terms of connection speed and consistency. Still, the 15-day benefit included with Visa Infinite is definitely a nice perk.
