Can I still put two numbers on the new phone from the postpay phone update program

Last year I changed one of my phone numbers to ATT postpay program. ATT set the number as an eSIM on my apple. The physical SIM in my apple is another number with a different carrier. So now, my apple has two numbers (two different carriers) on one device.

My new Sumsong device is purchased under the installment plan through the updating program. With my new device, can I still use two numbers on that? Since I heard the phones purchased from att will be locked with att carrier only. 

Thank you.
