Quote:The site lists +353 12161616 as the non-geo alternative but dialling this invokes BT's "incorrect" message.
Any answers please ( and what does the '+' mean ?)
+ is used to denote you must dial your countries code to make international calls. In the UK and the EU this is 00.
You will notice on your mobile when ever you text some one it will be sent / received in the international format ie) +4479...... 44 being the code for the UK.
If you travel abroad a lot and take your mobile, it is advised all you numbers in your phone book are in this format, they still work fine when using your mobile in the UK too, and you won't be charged any differently.
