FWIW, people were reporting phantom cellphone-like vibration perceptions well before smartphones, and before using them heavily. I think I felt it at least a couple times when not carrying my circa 2000 Ericsson dumbphone (maybe "https://www.gsmarena.com/ericsson_t18s-116.php https://www.gsmarena.com/ericsson_t18s-116.php"), though I'd hardly used it, probably most days had zero received calls or SMS. I don't know how much that's like phantom limb. https://en.wikipedia.org/wiki/Phantom_vibration_syndrome https://en.wikipedia.org/wiki/Phantom_vibration_syndrome
