i have purchased an iphone 16 with IDmobile, i chose to keep my old number by using a PAC code. when i opened the new phone i began setting it up, they asked if i wanted to transfer my data and i said yes and it all transfered so i could finally use it. i did not think the number had transferred so when i went to get the code of the temporary number i couldnt get the message code as the phone is no longer attached to the new phone. what do i do to activate my old number
