I found this for you. This is from a search on the help page. If you have any issues you would need to contact customer service and I would recommend Facebook messenger as I have had faster responses than chat.
If you are an existing member, it’s easy to transfer your service to a new phone with eSIM or switch to eSIM on your current device. Just follow these steps:
2. DOWNLOAD, OPEN, and LOGIN to the Visible App on your eSIM-compatible device
3. NAVIGATE to “Your Devices” and scroll down to "Switching phones is SIMple" then click on “Switch Now”
4. FOLLOW the on-screen instructions to transfer your SIM
IMPORTANT: Before we begin your transfer, an authentication code will be sent to your Visible number via SMS and your email address on file. Please make sure you have access to both during this process, and keep in mind that you may need to check your spam folder.
