Hello @BaFughi ,
Welcome to the community,
Are you on pay as you go or contract? 5G does not work on pay as you go.
Are you able to make calls and send text not using any app, but making calls via cellular and same with text?
Not sure why it is not working , but do you have parental control on? This could be the issue, which you can check via settings in the EE App? If it is on, that is why the apps may not be working and need changing.
If on pay as you go, you will need to make a refundable amount to prove that you are over 18, which you can do with a credit card over the phone or by going to an EE high street store, with photo ID.
If on contract, you can do this via the EE App and change it, this is done for security reasons, so that people under the age of 18 are safe, no matter what age you are, easily changed if the right age.
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.
