It worked but troublesome
To see if it’s on or not. Also not everything worked well, mostly apps had kinks.
When I returned to US, a lot of apps didn’t have logins cached when I went back to my mobile plan. This hasn’t happened when using international data on my service so something to think about . Minor inconvenience

Hi Megan! Thank you for the detailed feedback. We're glad the service ultimately worked, though we're sorry to hear it was troublesome to check its status and that many apps had kinks while connected. Network performance can sometimes be affected by local carrier routing, congestion, or coverage in certain areas, which may explain some of the app issues you noticed.
Regarding the login caching issue when switching back to your mobile plan in the US, this is likely related to how your apps and device handle the switch between networks, rather than something specific to our eSIM. We appreciate you flagging it, as this kind of detail helps us understand the full picture of the experience.
If you have any further questions, please don't hesitate to reach out to us at [email protected].

Having complimentary data and not…
Having complimentary data and not having to worry about using main carriers data roaming or getting a different country sim card.
Service is sometimes sporadic despite showing bars but most of the time it works well.
Would be nice if when the plan used up all the data it would trigger a text message or notification that it was all gone. It just randomly stopped streaming/loading without knowing the data allocation was up.

Thank you for your feedback, Ed, and we are glad the complimentary data saved you from roaming charges! We are sorry about the occasional sporadic connection. Regarding notifications, you can actually enable data expiry alerts directly in the GigSky app under Profile and then Notification Settings.

Good Customer Service
Great customer service.
The GigSky eSIM didn’t work for me unfortunately. I run my own business and wanted to check emails while on a cruise but the signal wasn’t strong enough for me to refresh my email inbox. I contacted GigSky upon my return, and to their credit, they refunded me immediately… the customer service is very good.

Thank you for your feedback, Stephen, and we are sorry to hear the service did not meet expectations during your cruise. Connectivity at sea can be affected by coverage availability, distance from shore, and ship structure, which can limit data-heavy activities such as sending emails with attachments and browsing websites. Regarding your refund request, please reach out to our support team at [email protected] with your account details and our team will be happy to assist you. Best regards, The GigSky Team

Worked well for LTE access in Taiwan and Japan
Used GigSky service in Taiwan and Japan during July of 2026. Not sure about whether it was LTE or 5G in taiwan. In Japan the connection was LTE, but speed was adequate for mapping, basic web browsing, etc. Coverage was good throughout the areas I visited (osaka, kyoto, hiroshima, tokyo). My credit card provided a free 15 day pass for GigSky, so I was very happy to have free usable cell coverage while traveling, even if speeds were not amazing.

Thank you for your feedback, David, and we are glad the service worked well across Taiwan and Japan and that the coverage was good throughout all the areas you visited! We are sorry the speeds were not amazing; LTE performance can vary depending on local carrier routing in each region. We are glad the free benefit made your trip more enjoyable!
