I decided to "take the plunge" and join 3 at the weekend. Been playing
around with the N73, but it doesn't want to store the SMS centre number
(I can send texts if I type in the centre number each time I send a
text).

If I try to add a message centre it tells me "Text message service
disabled. No message centres available on current SIM".

Any ideas, or do i need to call 3 customer service?
