Thanks for sharing Amani! In our experience your account will be live within one day. Depending on the moment you delete your account it is even possible to be back online within an hour. Please contact us at firstname.lastname@example.org to talk over the possibilities of planning this moment as good as possible.
For what's next: as soon as you delete your account we will be able to request your number to be activated. As soon as the number is activated in your account, you can verify the number. You will receive instructions on how to do this via email and after these steps have been done, you will be back online.
