@Porthbeach55 That’s because you need access to your account and if accounts are offline you don’t have access. EE do account Maintance when it will cause at least disruption to the vast major majority of customers. Around 11pm to 6am. This includes access to the app as that’s a link to your account.
To contact EE Customer Services dial 150 From your EE mobile or 0800 956 6000 from any other phone.
