Phone number to call when porting to ATT

Because the thing above, I have to switch my carrier from PagePlus to ATT.
And I went through a lot of waiting time and couple phone calls to make it done.
Here are they: 18003310500 - 18668027560 - 18663190749.

If you just want to port, the middle phone number is what you need.
1 866 802 7560 - people over the line was very helpful!
