You do know you can transfer your current number to your old clam phone if you so wished?
Um, yes, I do. Although, actually, I never got around to doing that, as I was working abroad at the time I switched phones, and thus, only used the antique Nokia when I was at home.
Now, it is a mad badge of honour, and is an extraordinarily rugged phone. Nevertheless, while I like the simplicity of the thing, the battery life could be better (well, okay, the phone is around 16 years old…..), and the memory for text messages resembles a twitter space - I'm allowed the proverbial 140 characters, which makes for succinct and terse messages.
Abroad, I always had work phones, although some of my colleagues used their iPhones for work (in other words, they changed the sim).
However, I shall probably get a second phone - with some sort of work number in due course, for a second, ad separate identity.
Actually, I'm giving some thought to purchasing this recently released iPhone 5SE, but that is a different topic.
