Regarding adding a line; moving a number
I'd like to take advantage of one of the AT&T phone deals present right now - to purchase a Samsung Galaxy S20 for $10/mo (or perhaps $15/mo, it was $10 yesterday) by purchasing a new "unlimited" line.
However, I would like to move a number over from preexisting AT&T line to the new line, effectively changing the plan and upgrading the phone, but hopefully utilizing the deal.
Some details I would like to hopefully know:
Is this possible? Can a number be transferred to another line?
Would this be cost efficient? I have a four-line normal plan now, would adding an unlimited line and removing a normal line make sense?
And, if it is possible, how would I go about doing this?
I would ask AT&T support, but the chat function does not appear to be working, at least for me right now.
