If you are upgrading your iPhone Xs, Xs Max or Xr to the new iPhone 11's and you have a GigSky data plan on the old phone and have done a backup and restore to the new iPhone, there are two things to consider;
1) If there are no active data plans on the device, please go to the GigSky App and Delete All Data Plans. This will remove all the information about the eSIMs on the account and allow you to purchase a new data plan and download a new eSIM
2) If you have an active data plan, please contact please contact GigSky Support and email@example.com. We will reassign a new eSIM to your new phone to allow you to download a new eSIM to your phone.
If you have any questions which of these two scenarios apply to your account, please do not hesitate to contact GigSky support, we will gladly provide assistance
