Refund policy

SIMs and top-ups can't be returned once sold and unused data isn't refunded; a minimally used subscription plan (under 1GB) affected by a connectivity issue may be refunded at GigSky's discretion. Read the policy ↗

Validity starts

Plans are turned on by the customer when ready to travel, not automatically at purchase, per GigSky's setup flow ('Activate When You Travel, Top Up Anytime').

Fair-use limit

On Unlimited plans, GigSky may reduce speed during a single day of very heavy use (e.g. video streaming); normal speed resumes the next day. No specific data threshold or throttled speed is disclosed.

Top-ups & rollover

Eligible plans can be topped up anytime in the GigSky app (My Plans > Top Up), with the data added to the existing plan; not every plan supports top-ups and complimentary Visa plans can't be topped up.

Lost device / reinstalling

If you delete your GigSky eSIM you may be able to download a replacement through the GigSky app; if you can't reinstall it, contact GigSky Support.

Billing currency

You pay in the currency set in Profile Details — USD, CAD, EUR, GBP or JPY — and that is the checkout currency; crypto payments are processed in USD.
