Hi and welcome, I'm not Samsung staff but a fan and not as posh
😊 as you with the Book5 Pro, but I do own a Book2 Pro 5G I5 and also a Book2 Pro i7.
I wasted neallrly £300 on an EE data SIM contract gor 2 years, probably actually used the 5G element less than 6 times, as initially I would use a Hot-spot, but now we have more integrated connectivity sharing when all devices are on the same Samsung account.
Even my car WIFI is pointless as I created a routine whereby when my ZFOLD6 hot-spot auto activates.
The only purpose I can see for me a 5G laptop being relevant is if my mobile SIM was basic with limited tethering or to avoid using say none home WIFI which maybe exposed, but again it brings me back to just use my mobile hot-spot.
