Upgrade

[Muzeyyen]

I am looking to upgrade my phone and would like to find out best deals.

Nobody can advise you on what is the best deal as that will be different for everybody.

Decide on how much data you need, how much you want to pay

Looks like you should contact the sales team they can help with that – message them on Social Media if yo can - on Facebook (https://o2uk.co/O2CFB) , 

X Twitter (https://o2uk.co/O2CTW) or 

 Instagram (https://o2uk.co/O2CIG)

Or you can call them on 0800 081 0255, free from any phone or landline

You @Muzeyyen probably won't get the best deal from your local O2 retail store, but a visit might aid your fact-finding and give you an idea of prices to compare against :-
