Hey Ephraim, thank you for your question. In general, porting each way can take 3-10 business days because we're moving the number from wireless status to wireline and then back to wireless.

Practically speaking, the whole process could take as little as a few days if everything works totally smoothly. You'll want to review these couple of articles from our help center and please reach out to our support team if we can help:
