Hello @Hoooyooo2525252 ,
Welcome to the community,
Are you on pay as you go or contract?
Did you use your SIM card in the UK before going to Germany? SIM cards have to be activated and used in the UK first.
If on contract, did you enable roaming on your account?
Have you rebooted your phone, done a manual search to find a signal?
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.
