I just ported my landline to Xfinity. Xfinity said to wait 3 to 4 days for the transfer to be complete. I'm not really sure what to do next. I've been using a modem that I purchased for my computer internet. It does not have a telephone port on it. My package includes unlimited voice. Do I need another piece of equipment from Xfinity? If so, I'm sure there will be another charge for this.
