Welcome back home! Now, all that remains is to restore the situation to its original state.
1
Open your SIM manager
Go to 'Settings' > 'Connections' > 'SIM manager'.
2
Switch off your StaffTraveler eSIM
Turn your StaffTraveler eSIM off.
3
Switch your own SIM back on
If your primary SIM was switched off while you were away, turn it back on.
4
Point mobile data back at your own SIM
In 'SIM manager', check that your primary SIM is the one set for mobile data, so your phone does not fall back to the eSIM.
