Change phone plan without changing my phone number
I was at an AT&T store to switch my plan from pre-paid to a post-paid contract plan. One of the reps at the store informed me that my phone number must change as part of the switching process. I can't even quantify the amount of disruption that changing my phone number will cause. As relates to updating family, friends, business contacts and online accounts, this will be a significant life event that I'm not ready to deal with at the moment.
Has anyone had success with switching plans and retaining their phone number? Otherwise, I'm considering abandoning this pre-paid to post-paid migration all together.
Any help and thoughts are appreciated.
