Yes, you can use any sim with it, they come with one but no need to activate.

Drop some airtags in your suitcases - helped us find ours when it ended up on the wrong belt/ and once dumped by the oversize/ pushchairs.

If the thief has an iPhone he will know he's getting tracked

What gave you that idea, it can be either hardwired or charged up at home and used via the built-in battery.

I’m with you.
I’ve got an old Peugeot 207 and I loathe it. I leave it in high crime areas with a £50 note and the keys on the front seat, along with a full tank of petrol, maps, a change of clothes and fake passports.
It’s still there. No self respecting gangster is going to nick it.

Had my tracked car returned to me within 2 hours of it being reported stolen. Perhaps some counties perform better than others.
Also, I get about 10% off of my insurance policy for having one

This is the same item. I purchased it when it was the lower price and it does exactly what I wanted 🏼

Ghost II.

It immobilises the car unless you press the correct button combination inside the car first (and it can be more or less whatever you want, like vol up, skip track, etc etc)

No - both require a compatible device to be in range to return a ping. They're great in built-up areas, but in smaller urban areas or the country, they become next to useless.

With these trackers, all the devices require is a phone signal (to send data back to the owner) and GPS data (for location); both are continually sent, so even if it's taken to a "dark" location, you can see exactly where it has been, and the last location before any signal goes dead - something you can't do with air tags

Air tag also has an anti-stalking app where anyone can tell if an air tag is in the vicinity, create a sound, and then any thief can remove it.

Air tags have their purpose, but not for comprehensive tracking.

During which time you go and collect your vehicle. 🥲

Let’s get things correct first. If you have a in your words a desirable vehicle you wouldn’t have this fitted. You’d have a proper hidden tracker fitted correctly not some toot from a supermarket. That way they don’t generally find the tracker in minutes.

Is it live tracking? Or do you need to send a message to get location?

Sure If you want something not the same you might as well hide a bit of toast.

And you’ll end up in jail if caught. An acquaintance of mine was sent for 1 year behind bars for this reason.

Am I right to think that insurers will only offer a discount if the unit is appropriately certified?

And if so, does this unit have that certification?
