I have recently renewed my contract with a new phone and on my bill I am charged £13 for Ess Device 4GB . I don't know what this is? Can anybody help?

Hello @buffygirl16. 

Thanks for coming here. 

Is there a mobile number attached to this?

When you log in to your EE account online and select this line does it show what device it is linked to?

Speak soon, 

Katie
