AT&T simcard does not work on Google Pixel Verizon

[AC Question]

I just got Pixel from Verizon.
I inserted AT&T simcard from my Galaxy 7.

Text messages and internet works (without wifi), but i cannot seem to call or receive calls.

Anyone had the same issue..?

Probably because the device is locked to Verizon surely? Have you spoken to any of the service providers about this issue?
