*SueDonim, I knew I wasn't the only person with this problem! There are many reasons why people cannot, or have difficulty, using mobile phones, that are not technological.
Dyspraxia, like dyslexia etc affects people different ways. When I was diagnosed, I had some specialist pysiotherapy that helped, but I also have a problem with distraction by outside events, ambient noise and I do not like using a phone in busy places. Even at home, with a landline phone, I will go into another room by myself if a phone call is of any length or concentration is required and I do a lot of things with my eyes shut to remove visual distractions. DS, whose diagnosis of dyspraxia led to me being assessed, does manage with a mobile phone, but his dyspraxia manifests in different ways, his problem that is he is never sure if he can find it!
