Thanks for the tip.
Unfortunately the list is relatively short as I have tried a number of phones to find the ones with screens that I find 'easy on my eyes'*. Of those I have now found a deal that I am happy with online and pressed the penury button.
By tomorrow evening I should be back up and running, accessible to clients, friends and family alike, and, hopefully without worry of techno-isolation for another three or four years. By then I hope that the next big step in personal tech will have been taken and there will be less need for me to actually read bloody screens!
* As my sight is deteriorating so small screens are getting more and more difficult to use.
