Unlocking Iphone to use on another network

[Richard11]

I have recently changed my network provider from O2 but when I put the new sim card into my Iphone 5 I am told that the phone needs tio be unlocked. I have tried on many occassions to get though to O2 to unlock my phone but as my co ntract with them was terminated last week I am unable to get though to speak to anybody.  Have you any ideas please ?

Thanks jonsie but I have tried these but with no joy, I maybe wrong but I think that the problem is that my phone number was "ported out" last week and now O2 no longer recognise my number

Can you assist with this @Marjo ?

@Richard11 

Your number will still be associated with your IMEI number.

Have you tried the manual form in the link?

[Richard11]

I have tried the link a few times now - only managed to complete it once but was told that I had not passed the security checks. All the other times i get the message "oops something has gone wrong" after filling in the form. I am more than happy to speak to customer service about this but cannot get through using my phone number. Is there anyway to bypass this ?

Try any O2 number if you know someone on O2.
