New sim

[AJ22]

Hi there I need some help to get my new sim up and running. I have no service currently so can not access my o2 app or log on online due to needing a text conformation for a code. Can you please help

You will need to contact O2 for that, @AJ22 - Guide: How to find help & contact O2 has all the ways.  Or take phone and SIM into an O2 shop, with some photo id, and let them do the job for you.

Pay monthly

Customer Service	Number	Charges
From your O2 mobile	202	Free
From a landline	0344 809 0202	Standard UK Rate
From abroad	+44 344 809 0202	Free from an O2 phone

Good luck!

@AJ22 To add to the advice from @pgn, if you can't get to an O2 store and want to call, download Skype to call for free on 0800 032 1402.  Guide: A Guide to Skype 

When it comes to the reason you are calling, stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say 'Upgrade', 'Lost/Stolen', or 'Fraud' if the suggestion above doesn't get you through.
