Hi @Mehmet30 It's brilliant new that you're looking to upgrade your phone.
You can upgrade your phone through your My EE account.
If you'd prefer to speak to one of our guides, you can pop into one of our stores
If you'd like to speak to us over the phone, you'd just need to dial 150 from an EE phone, or 07953 966 150 from any other phone.
