Hear Voicemail from another mobile

[no0ora31]

Hi,

I have a PAYG O2 number that is out of credit. 

I would like to check that number’s voicemail from my original O2 monthly-paid number without having to put any credit on the PAYG. Is it possible to do that?

Thanks!

Do you already have a pin for your voicemail? If so dial your number from an alternative phone. Interupt the voicemail greeting by keying *
It will then prompt you to enter your pin, then option 2 to listen to your messages.

Don't know if the default pin works that way Usual Default is 8705

Thank you Enlli for your response. 
I do have a pin number and I tried the method you mentioned but I don’t get to type my pin number and the phone is hanged up from the O2 end after this:

”to keep your pin secure, you must change your pin. If calling from another number, try calling from your mobile. If calling from your mobile abroad, please try again… goodbye.”

Thanks for your response. 
I saw that page before writing my question. I googled every possible solution but ended up empty handed.

I don’t have a landline to try that method either.
