SVG2482AC is designed and manufactured for Xfinity and it is only compatible with Xfinity alone when customer need both the voice and internet service. If only need to activate internet on SVG2482AC then it is compatible with all service provider so please do check with your service provider for activation again.

I do have Internet and voice and was told by 2 different X- Finity agents it was not compatible. 

SVG2482-AC is compatible only with an Xfinity internet service provider. I suggest trying self-activation through the Xfinity application. 

I request that you follow the steps on the below-given link for the first-time activation:
