Cannot unlock SIM

[Denise-Ben]

Hello.  Trying to swap to vodafone from o2 and cannot get the sim to read.  Phoned o2 who told me I need the PUK code which I have got but I don't have anywhere to enter it.  I've tried looking on the o2 SIM which is no longer active as it's been switched off.  When I enter the new SIM (Vodafone) it says Activation Required with 'dismiss' underneath.  Then I got to a screen that says updated completed - continue - SIM not supported.  Enter  sim that's supported.

I can't log into o2 to enter the code as it says I don't have any services or products with o2?

Please help.  I'm front line staff and I need my phone!

What doesn't work?

I cannot fill out the manual form because it says I don't have My o2.  I've just been on and changed my password to log in and it's still saying 'oops something went wrong' at the top of the form.
