I’d like to change this number to my old number
What happened to the old number? Do you port it to another carrier or did you cancel the service associated with the number? If you canceled without porting it, it was likely released to the available pool of numbers and recycled already. It is quite likely someone else was assigned that number already.
Hello, nikki_bee142, we can certainly help to see if we are able to change your number back to your previous number. So we can better assist, we will be reaching out via Private Message.
