Welcome to T-Mobile and our Support Community! Sometimes it can take 2-24 hours to fully port over your number and in between that time period you may have dual service with your previous carrier. To chat with a representative, you'll need to go to your My T-Mobile account (which is likely not set-up yet) and the chat with us option should be available. Another option is to contact T-Force, our social media Customer Care team, via Facebook or Twitter to see why your services are working.
