This is not a recommended action, however, the only instance where this would be required is if there isn't enough space on your phone to download a new eSIM.
If you need to erase your eSIM, follow these steps:
- Go to Settings > Cellular.
- Tap the eSIM label you want to erase.
- Tap Remove Cellular Plan.
- Tap the label, it may ask you to sync contacts, select your Primary line and the eSIM label will be erased
If you want to cancel your cellular plan, contact GigSky Support at firstname.lastname@example.org and provide your account information and the plan you wish to erase
