user_hvrs2n Thank you so much for reaching out for help with your questions about activating a modem you are using with another provider. I am not sure about Asountd, but with our system, there is a 24 to 48-hour delay in removing the modem from a previous account before it can be activated on a different account. Once removed, however, as long as the modem is one of the 3rd party devices we support, activation using the Xfinity app only takes a few moments.
