2 Phone numbers on ONE PHONE... possible??

Hey there @Thayerzoo One hour on the phone and no solid answer? Wow! There are a couple ways that you are able to get two numbers on one device. I see that you posted this thread in our Apple forum, but I never want to assume facts that can affect the answer. What phone are you using that you want to get two phone numbers on?

No matter what device you are using, you can use our DIGITS service to get two T-Mobile numbers on one phone by using the DIGITS app. It is free to install and easy to use. We have tons of great information about it on our Support page, so check it out. https://www.t-mobile.com/support/plans-features/get-started-with-digits?cmpid=hw_send

If your phone supports dual SIM, then you could have your eSIM profile assigned to one phone number and then your physical sim assigned to another. This is an option for both two T-Mobile numbers or for one T-Mobile and one other carrier like @gramps28 mentioned above. 

Are you trying to use two T-Mobile phone numbers or one from another carrier? Are both numbers already active or do you need to add a new line? A little more information can help us provide a more detailed resolution, but I hope this information helps a bit.
