Cool and all, except calls won't work in lockdown mode on prepaid SIMs. Like, at all. I learned this the hard way, accidentally, after weeks of emails with my provider, then even migrating to a different provider, setting up my phone from scratch, etc.

They might as well fix it, but I'm sure they won't.
I've used several prepaid SIMs on my phone in lockdown mode without incident since 2023. Both in the U.S. and overseas.

But if you enable lockdown mode, the usability of your very expensive device tends to zero... ¯\_(シ)_/¯
If you were to turn it on, you would want to turn it off as soon as possible lol
It makes your iPhone unusable in a day to day life
There's only a few things I've missed. Hardly unusable. The main thing I've missed is OTP texts no longer being autofilled into two factor prompts. Websites that have issues you can toggle on/off in per-website settings. Other than that I haven't had a negative experience.

Amazing that Apple provides this.

If you’re a politician, activist or journalist who has a ‘work’ phone with this on, you’re not going to be upset about the minor loss of functionality (because it’s for work).

If lockdown mode is that great and virtually unnoticeable to the user as promised here by some, then I have to ask:
Why do I have to enable it manually and why isn't this feature hardcoded into the OS instead? 🤔

The same reason why other features on iOS are optional. Are you trying to play some kind of 'gotcha' game with your question?

I use Lockdown Mode and haven’t had any big issues with it.
But Apple’s claims have to be taken with a little more than a pinch of salt.
There was at least one known vulnerability that could be exploited on devices with Lockdown Mode enabled. https://thehackernews.com/2023/12/new-bluetooth-flaw-let-hackers-take.html
And Apple only acknowledges hacks when publicly confronted with the evidence. For them, every two months happens “an extremely sophisticated attack” 🙂
 


Apple says it has no record of a successful spyware attack against any device running Lockdown Mode, the opt-in security feature it introduced in 2022.

"We are not aware of any successful mercenary spyware attacks against a Lockdown Mode-enabled Apple device," an Apple spokesperson told TechCrunch.

Lockdown Mode is available on the iPhone, iPad, and Mac, and dramatically restricts certain system features that are commonly exploited by mercenary spyware. When enabled, it blocks most message attachment types, disables certain complex web technologies, and prevents devices from automatically joining non-secure Wi-Fi networks, among other restrictions. Apple designed the feature specifically to protect high-risk users such as journalists, activists, lawyers, and others who may be personally targeted by sophisticated nation-state-level attacks.


Donncha Ó Cearbhaill, head of the security lab at Amnesty International, said he and his colleagues "have not seen any evidence of an iPhone being successfully compromised by mercenary spyware where Lockdown Mode was enabled at the time of the attack." Digital rights organizations including Amnesty International and the University of Toronto's Citizen Lab have documented numerous successful spyware attacks on iPhone users over the years, but none have involved a bypass of Lockdown Mode.

Citizen Lab researchers have confirmed at least two cases where Lockdown Mode actively blocked spyware attacks, with one involving NSO Group's Pegasus and another involving Predator spyware, made by a company now part of Intellexa. Google researchers found that spyware was coded to abort its infection attempt if it detected Lockdown Mode was active, apparently to avoid leaving traces that could expose the attack.

Patrick Wardle, an Apple cybersecurity expert, told TechCrunch, "I think it's safe to say, Lockdown Mode is one of the most aggressive consumer-facing hardening features ever shipped."

Article Link: Apple Says No iPhone in Lockdown Mode Has Ever Been Hacked
Saying an iPhone in lockdown mode has never been hacked is an invitation for the world’s hacking community to try to break the lockdown mode feature. It is a bit dangerous.
 
Lockdown mode unfortunately makes the Apple Watch useless as calls no longer ring it. Anyone who actually needs a working phone and has the watch to avoid missing calls cannot use this mode. It doesn’t quite make sense to me that the watch has its own lockdown mode that is always enabled in tandem with the iPhone lockdown mode. Incoming call and text notifications is what my Apple Watch is for. If I didn’t need notifications to alert me quietly on my wrist I could wear literally any other watch or none at all.
