Sound and Camera
The Siemens SL42 was not equipped with a loudspeaker or a 3.5mm audio jack, reflecting the era when phones were slowly moving towards multimedia capabilities but were not fully there yet. It relied on vibration and monophonic ringtones for alerts, which could be composed by the user, adding a personal touch. Notably, it did not feature a camera, as mobile photography was still in its infancy at the time of its launch.
