How do I port my old ATT number.
I had an ATT land line number for 25+ yrs and then now only use a mobile number with another carrier. I would like to "own" or use the old land line number so I can eventually connect it to my mobile number using google voice. I understand the number has to be ported to a mobile number and I will need to purchase a mobile phone/plan to transfer "briefly" to a google voice number. So, I can then access calls thru my mobile number ( different carrier, Not ATT). BTW, I do have a ATT Internet account, but that's the only ATT account I currently have. Any help with this process, is appreciated in advance.
