It took years, three different shell companies, and an explosive called pentaerythritol tetranitrate, according to reports.

That blog post describes how it works in more detail. We now live in a world where any battery could be a bomb, there is no way to detect it and the equipment for making those bomb-batteries costs $15k on Ali Express.
I had a feeling that this war would start something like this. Israel has been a testing ground for advanced military technology/ideas for a while. Now that they are engaging in war it was inevitable that techniques or ideas that they have been hiding would eventually get used leading to the world being more dangerous than it was before.
Also as a side note this is why low tech is such a good idea. A small amount of dependencies usually means something is safer in the long run.
Going low-tech is what got them here. The change to bulkier devices gave Israel the opportunity to insert explosives. Using existing small devices would not have given them that opportunity.
Of course, that would mean Israel could continue spying on their cellular communication. It's a risk calculation.
Well maybe I should've been more specific. The reason why I mentioned low tech is because it tends to favor localized production and tech that can be easily repaired/modified/created. The pager and walkie talkie attacks came from them not having control over how the tech was produced. If they did have control over that then it would be less likely that this happened and even if it did they would be able to recover quicker.
PS I actually don't really care about Hezbollah doing this. They suck. It is just in principle it would be better.
