How to temporarily disable Dual SIM on iPhone XS Max
I am using an iPhone XS Max with 2 SIMs (the China model with Dual nano SIM tray, not the eSIM version).
How can I disable the secondary SIM, while still leaving it in the SIM tray?
For example, to disconnect a line to avoid being disturbed, but not the second one. A bit like a "Do Not Disturb" or "Airplane" mode for a specific SIM
