problem with voicemail on sony ericsson?

[oliviaexoxx]

it says that i have a new voicemail....
then i ring voicemail and it tells me to 'enter PIN'
...even though ive never made a PIN number and dont have one :s
it never did it before only just started a few weeks back?
any one else experienced this?
thanks

Well Once i had the same problem and i just typed in 1234 and it accepted it or if that doesnt work try the 4 last diqits of your number.
