The Telecom website
"If you didn't buy your mobile phone from Telecom, you'll need to update your mobile settings to get TWorld and WAP. ... please contact our mobile helpdesk on 0800 800 163 and we'll re-send the text message so you can update your settings ..."
I rang 0800 800 163 and the CSO reported (after consulting the "Mobile Team") that they were unable to send the settings at present. When I asked if they would be available in a day-or-two, her reply was that they have been unable to send the settings since just before Xmas 09, and there was no ETA. However since others appear recently to have received settings by SMS for certain other 'phones, I wondered if in fact there is another aspect (ie non-Telecom-supported model).
