This means that the pre-approval for GigSky purchases in your PayPal account has been deleted or has expired.
You must remove your PayPal account as a payment method from the Gigsky app, and then add it again.
NOTE for Apple SIM customers: It is not possible to add PayPal as a payment method through the iPad Cellular Data interface. Instead, you must use our web client:
- Log into your account using a web browser at https://app.gigsky.com/#/login
- Go to the menu and select Payment / Payment Methods to find the option to add Paypal.
- Add your PayPal account.
- Go through the procedure for buying a GigSky data plan from the Cellular Data menu on the iPad. PayPal should now be available as a payment method.
