Hello @Rachel0723 ,
Welcome to the community,
What do you mean change a new phone number?
Do you want to get your phone number changed or is it that you have moved from another network and want to keep the number you have had up to now? If the latter is the case, then you will need a PAC code from your previous network and will need to give it to EE.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
