Unable to email current at& phone bill

You can scan your bill into pdf and attach that file when you submit your port request.
I remember using my free fax service (didn’t have scanner where I was at) to get the bill in electronic format. (http://k7.net/ I fax myself, then k7 sent me the fax in electronic format into my email inbox).
