I have recently moved to New Zealand for 6 months. In an attempt to keep my UK phone number I chose to continue to pay my monthly fee while away. While I am here, I got an eSIM with a New Zealand number. This set up went well and in the Setting>Network and Internet>SIMs section I could see my two SIMs both active. Then I set the New Zealand SIM to be the primary for calls, texts, and data. While doing so, I accidentally flicked the toggle switch on my UK ID provided SIM to the off position. Rather than being available to switch back on, it completely disappeared from the list. I have attempted to take the physical SIM out, reboot the phone, and then reboot again with it back in place however this changed nothing. For context this is on a Google Pixel 9 which can handle multiple SIMs. Any assistance would be appreciated.
