Installing a UK eSIM and starting its validity may be separate events. Read the product instructions before scanning the QR code.
Quick answer: Install on stable Wi-Fi before departure, label the profile and follow its activation timing. In the UK, enable the eSIM, select it for mobile data, turn on roaming for that line and test with Wi-Fi off.
