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?
Don’t glue it shut, paint it shut with an acrylic paint or nail polish. Try to stick to the surface with the paint - you could even paint it to cover it/obscure it’s location as well.
This way, if you ever need to remove it you can delicately dab acetone over it to dissolve the acrylic and it will open once again!
This is amazing! Thank you, I will definitely be painting it closed.
Get a metal case, weld it shut. Connect it to a long chain and a 25kg dumbbell. Guaranteed they won’t rob you of your phone.
This is the best tip so far. Thank you so much!

Ahh imagine carrying on one side for too long, the back pain…
Maybe I could also look into hiring someone to carry the setup for me, that way I can have even more peace of mind knowing I’m protecting my health and my data! /s

SIM cards do sometimes malfunction, so if that happens and you glued it in you’re kinda screwed.
This is also true, maybe there’s another non permanent way of doing this? I only need the SIM card in the device when it’s stolen long enough for me to remotely wipe the device
Well, either you glue it, and if you ever need to switch the SIM, you buy a new phone. Or you buy a new phone with eSIM support now.
I guess the only other option is to have a case that’s hard to get off to buy you some time?
There isn’t really a point to that. The very first thing thieves do is turn off the phone so you can’t track it. They’ll then usually format your phone and sell it. Best you can do is set up a secure password and not show any info on the lock screen so they at least wouldn’t be able to access your stuff.
True, but in my country and in my experience the first thing they do is remove the SIM card so that you can’t track it, if it’s an android which it is in my case.
I’ve got a secure password and no details on the lock screen but I’d just like to try protect myself even more
Samsung devices require the unlock pattern/code to be shut down.
Umm… no they don’t? You need a password to unlock it after restarting it but you absolutely can turn the phone off without a password. I’m on my 3rd Samsung device and have never entered a password to shut any of them off.
Every Samsung device I was handed over the last few years required to enter the unlock code for it to be shut down. Maybe it is a dedicated setting or something?
Pretty sure every single mobile has a key combination to power off and recovery when your display or touch isnt working properly. At least its the case for my samsung m51.
Amd what do they do if the battery runs out? Suspend to disk?
and thiefs will just throw it into a faraday cage to block the signal immediately.
Not in my country lol, they’re not that smart
Not in my country lol, they’re not that smart
Depending on how they get stolen, I’d carry a decoy.
Not a bad idea actually. I do have a work phone which I could hand over but if I get frisked they’ll find the personal phone anyways
…What awful country is this, that your phone gets stolen?
Every country
Never seen or heard of it happening since screen locks became common.
That doesnt really stop them tho, they can still find a way to format it and sell it. Maybe some models can require password for reset but there must be one way or another to do it for doing necessary repairs.
And yet, you would think I would have seen or heard someone complain about theft before now. Everyone has one. This international location is the only place. Thus my assumption that it is some remote country. Doesn’t happen here in Australia.
That actually worked for me once. Handed over my old Nokia brick phone and kept my Motorola flip lol.
But what about a decoy for the decoy?
The federal government has had difficulty dealing with modern locked phones. The sim isn’t integral to the security of the device, it’s just a pointer for the carrier to route calls to. A modern phone with whole system encryption and a strong password is going to be protected against most everyone including nation state actors.
The only real advisory I like to put out with regards to phones is the same as most other devices, don’t reuse passwords and for two factor ideally use something other than email or SMS which makes it far more difficult to get the second factor.
The other thing that’s kind of a ‘best practice’ is using a password rather than any kind of biometric. The reason there is last I’d read (in the USA) the current legal guidance is that while authorities can compelle someone to put a finger on a screen or look at the device, they cannot compelle them to open the contents of their mind (forced testimony) due to the 5th amendment protections. Of course that kind of thing is more related to legal situations rather than lost/stolen devices.
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.
- PluckLockEX: (No longer maintained) https://f-droid.org/packages/xyz.iridiumion.plucklockex
- PrivateLock: https://f-droid.org/packages/com.wesaphzt.privatelock
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 :(
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
you really shouldn’t be recommending things that adds attack vectors.
Some phones including Samsung are encrypted by default.
Don’t keep data on your device you don’t need and use the encryption.
that doesn’t help with sim removal. sim swaps are stuff are a thing and honestly more of a concern than data exfiltration.
“meaning I wouldn’t be able to remotely lock or wipe my phone”. The original post indicated data was the issue. If they want to get the sim out and wipe it, they will. Need to solve the problem (data loss).

Uhm, I don’t care about the device or the SIM card?.. I care about my data, and I care about remotely wiping the device before they can try access the device if they are even trying to access it in the first place?
Sure they can turn it off, but if I activate the command to wipe the device the command will execute as soon as the device is powered on.
This is not the case if they remove the SIM. If they remove the SIM the connect is lost and the device can remain on and be tampered with, with my data still entact.
I don’t “keep asking for proof” I literally asked in one comment? You seem very angry about people asking questions online, maybe you should do some introspection or something idk

This is unfortunately how a lot of online privacy communities feel. Like it’s mostly performative privacy fan service. Often with a weird martyrdom thread running through it, almost as if people are mixing up the ideas of privacy, with simple rebellion against modern technology.
I can’t speak to any particular communities, but to me it’s about putting extra steps between me/my data/whatever and thieves. (I have a personal tinge of rebellion against social media and perma connectedness but I generally see them as separate)
If my password is “password” anyone can and will pop it
If my password is “P@$sw0Rd60&4” alot of people could and probably would
If my password is ^ and I use 2FA, sure that can be spoofed but the number of able hackers is much lower and it’s much more work, quite frankly I’m just not that interesting 😂
Etc etc, adjusted for situation
A better option would be to use a good password generally and the built-in lost device functions like Find my iPhone, Google Find my Device or Samsung Find my Mobile.
If you’re using Android, and want a separate app that can lock down your device outside of the built-in functionality, among a ton of other features:
I used to use Cerberus years ago for that security before that functionality was really built in. It is a side loaded app that allows remote tracking, lockdown, etc. and functions as a system app. They have a version of the apk that is listed as “System Framework” with a stock Android icon and as well to hide in the app listing. You can have it hide the app and access it via a dialer code as well for added security. When I used it, you could have it take photos to send to your email with location data for incorrect login attempts, send messages to the device to display while lost, etc. www.cerberusapp.comStill no use if the SIM gets pulled, therefore losing connectivity and rendering any Find My Device app useless. Unless I’m missing something?
Of course nothing will work if the SIM is removed, no new SIM is inserted, and they don’t connect it to Wi-Fi. But at that point, whoever has it also isn’t using the device either are they?
There is no way to have a device know it is stolen and wiped without it being able to get that notification from somewhere.
If that device is connected back to the Internet though, all of the find my device services work just fine, and you can queue a wipe to wait for the device to be online again. None of them are reliant on your SIM or phone number, they all use the MEID/IMEI and your Apple/Google/Samsung/etc. account to manage it.
To actually answer your question:
Super glue would be a decent option. You should only need one drop to secure the tray.If you ever need to open the tray again, wet the area with isopropyl alcohol for a few minutes, and it should pop right open without damage. If you get too much resistance, add more alcohol and wait a little longer.
There is also a 2-part epoxy with similar performance called “Doubkr Bubble” that also dissolves with alcohol, but it’s definitely overkill for a SIM tray.
If you can open it, they can open it. There’s not much of a point if it’s something you can undo.
Same deal as putting a lock on a door. Buys time
Exactly this. I’m looking to buy time not to completely bar access

It at least provides resistance to the immediate removal of the card. I doubt most thieves are running around with readily available solvents. Could provide enough time to remotely lock or wipe as OP said
deleted by creator
Amazing, thank you! I think the super glue option will be best. The phone is water resistant as well so I don’t see the isopropyl being an issue to try loosen the super glue.
With the phone off, the isopropyl should be safe. It’ll dry quick, too.
Hot glue can be undone with heat
It would give me enough time to remotely wipe the device before they can remove the SIM would it not?
No, they can do it with the phone turned off.
I mean on average theyll just turn it off and then try to factory reset it later which will remove your data if there isnt an exploit. What i do since I have the same problem, is just not keep any data on my phone the same goes for accounts but I see that might not be for everyone. Assuming your phone is fully updated a long passphrase, think stock android limits to 17 characters, should be enough to keep out the average drug addict. Be mindful of your surroundings, dont fight back unless they try kidnapping you and use lockdown mode or fully restart your device when you go to a shady area. Curious what device do you have?
Edit: what you should be more worried about are the assholes that force you to unlock it and then empty out your bank through the countless digital payment methods. Arming yourself would be the answer for that
Thanks for the response. I have a Samsung A34. I don’t think keeping accounts off of my phone would work for me, it’s my most central place for everything which I know is risky, but it’s better than having everything on my work computer which could get searched or taken at any point
Alright so did a quick search and couldnt find a way to bypass the lockscreen so that should be alright assuming they dont take it when its unlocked but do more research. Go ahead and set a short timeout, and get a privacy screen protector so shoulder surfing can be ruled out. Yeah that is risky but life is life you have the decision on that. The dummy phone is also a good idea if you leave behind the personal one imo
Have you thought about using a strong unlock method, so they can not gain access to your data in the first place (if all you want to do is wipe it)?
I’m on a Samsung A34 using a passphrase to unlock, I’m not sure it gets stronger than that? Unless there’s something I’m missing
having proper hardware security like is present on pixels would help a lot. if you can, look into a pixel and put grapheneos on it. I know it doesn’t solve your sim removal issue but the documentation can walk you through a lot of that.

If I really had such a concern I’d use a Linux phone, e.g PinePhone or PinePhone Pro, and I would program it so that unless a certain command has been ran, if it boots or stay too long (e.g 1s) without a SIM then it deletes sensitive data.
Or a rooted android.
1 second?
