Its not THAT effective in warzone, thats why you do not hear much about famous turkish UAV's anymore. It is very easy to distress any signals in area using low qualified soldier (driver + operator) and RLB-vehicle. When we see a drone putting a grenade (whatever side of conflict it is), ok, great, you wounded 2 soldiers in trench. What about other 12.998 that nearby?

Logistically speaking, the size/weight of improvised explosives that deliver results terrorists are looking for are typically too heavy for small drones. Terror devices also typically employ various amounts of miscellaneous shrapnel, to get the most effect out of limited explosive power, but also significantly increasing payload weight. To make any use out of explosives that weigh enough to let the drone still be pretty fast, you'd have to swarm them. That'd be a pretty effective tactic, but it obviates the benefit of drones over just using any other long range weaponry, precision guidance. If you're just going to spray and pray, do it with something bigger. For super precision individual strikes, a racing drone could maybe take out small targets, 1-3 people, but that's not a terrorists target. And even worse for those cases, they're extremely loud and easy to spot, they wouldn't be too difficult to evade. They're fast and nimble but that's relative, you're looking at 60mph averages, especially with a payload. You can dodge a 60mph car, you can probably dodge a 60mph drone.
They're honestly most effective in Ukraine because Russia is just terribly incompetent. For military use they're effective at rendering stationary equipment inoperable, or taking out a lead truck in a convoy, or blowing up an ammo depot. They're easily deflected with proper equipment since we know what tech they're using (2.4ghz or 900/433mhz control links, 5.8ghz video links), Jamming them is actually easy, just Russia sucks and can't wipe its ass and shit on its elbow at the same time. If they had enough explosive capability to, say, blow up a bridge, you can bet the Kerch Straight bridge would be gone by now.

Apple has stored a digital SIM on the cloud backups for ~5 years.

Cellular Apple Watches have a digital SIM, which is part of the user profile that’s regularly backed up.

>Sim card is the carrier information, all the sim card does is give you a phone number.

Not exactly. The physical SIM holds the ICCID which is a 22 digit code that’s unique and holds redundant information alongside your personal identification.

For instance it holds your country and network. That’s really not needed on a smartphone, it’s been done digitally via carrier settings and GPS for over a decade.

>Phasing out sim cards is a bad idea, now your hardware is locked to your phone number.

That isn’t how this works. You can change networks and phone numbers with a digital SIM. It’s just carrier settings.

In fact, the current digital sim iPhone can support 8 different phones numbers on one handset at one time.

Think of it like setting up aa new email account. Your phone isn’t tied to the one email, and the email isn’t tied to your phone. It’s just a communication route.

>When your phone dies you don't have the luxury to take the sim out and use another phone.

No, you have the luxury of just signing in on another phone and your entire profile (including the digital sim) downloads to your device.

Even worse, I was just reading (I think on Hackaday) that at least some DJI drones transmit both its location and the controller's location coordinates unencrypted.

The thing is, you take that into consideration and there's ways you can mitigate the risk in that. Also, how quickly can the Russian figure that signal out, convert the drone coordinates into whatever they use, and pass that to a gun or missle battalion fire direction center? As well as how quickly that FDC can get that to a gun/missle section that can engage that coordinates? I'm sure the Ukrainians can say, with fair accuracy by now.

Phasing out sim cards is a bad idea, now your hardware is locked to your phone number.

When your phone dies you don't have the luxury to take the sim out and use another phone.
