What if my phone carrier isn't listed as the source carrier?
> [!IMPORTANT] > Skype for Business Online will be retired on July 31, 2021. If you haven't upgraded your Skype for Business Online users to Microsoft Teams before that date, they will be automatically scheduled for an assisted upgrade. If you want to upgrade your organization to Teams yourself, we strongly recommend that you begin planning your upgrade path today. Remember that a successful upgrade aligns technical and user readiness, so be sure to leverage our upgrade guidance as you navigate your journey to Teams.?
It's a little confusing when you see that the name of your carrier isn't listed. In most cases, if the service provider or carrier is different, chances are that the phone numbers you are transferring over are owned by a different service provider or carrier. There can be times when the service provider or carrier that is listed could be different from your current service provider because your current service provider may be working with a third-party service provider.
If you are porting number from Skype for Business as your carrier, you might see Level3 listed.
