There was a GSM version of that Nokia phone from the original Matrix film sold around the world. Are GSM radio bands from the late ‘90s/early 2000s still in use? If so it would presumably still work for calls and texts in some countries.

The spring activated thing in The Matrix was only in the movie though. On the real phone you had to actually pull that plate down yourself, which made the phone seem like a complete disappointment back in the day when I once met someone who actually had one. This person could sort of fiddle it with their hand to kinda push it out one smooth motion, but it just wasn’t quite right.
