@Oli7 reboot the phone and check again
If the PM eSIM is really gone, you can rebuy one for free
To rebuy new eSIM for FREE, first, download the app on your phone and login. If you have problem receiving 2FA code, click "Didn't Receive code" or "Resend code" and choose either Send email or Send voice message
Once logged in, Click Account from the bottom, then click Purchase SIM Card and select eSIM.
Once it confirms your phone is eSIM compatible, click Pay $ and Install (the system will check and apply a $5 credit to bring the total price back to $0 at checkout), and follow the prompt to complete and purchase and install eSIM on your device
(in rare case that PM charges you for the replacement esim, you can submit a ticket with PM support and ask them for reimbursement)

While direct eSIM to eSIM transfers are not supported, we do offer the option to transfer service from one eSIM to another by purchasing a new eSIM. If you are already using a Public Mobile eSIM, when you request a new eSIM, we automatically identify you as an existing eSIM user and waive the replacement fee, provided you meet certain conditions.
To qualify for a fee waiver when transitioning between eSIMs, you must meet the following criteria:
* The current Public Mobile eSIM must be actively installed in the device you’re transferring from.
* The eSIM must have been purchased at least 15 days prior to the new request
