I know it’s an odd question, but where I live phones get stolen often. My phone doesn’t have the option for an eSim, which is a problem because 90% of the time when a thief steals a phone they take out the SIM card immediately, meaning I wouldn’t be able to remotely lock or wipe my phone.
Should I consider glueing the SIM tray shut? Or are there alternative less permanent measures I can take to keep my device secure?
I might recommend using something like tape. Extra Strong Clear Tape.
You may also want to invest in a phone case; preferably an opaque and waterproof one that is difficult to remove.
There are apps available on F-Droid like PrivateLock which might help too; this will automate locking your phone if it’s snatched from your hands suddenly.
Last thing I can say is to use a short screen timeout and a strong password to unlock the phone.
Private Lock also hasn’t been updated for four years :(
you really shouldn’t be recommending things that adds attack vectors.
Do not use privatelock! It has the possibility to permanently lock your phone! For me it had a bug with the sensor and it was very hard to remove
