I recently purchased a new phone that came with a new SIM which I did not use and put my old SIM into the new phone. I would like to add a line to my family plan using my old phone with the new SIM card. The option to add a new line on the T-Mobile app requires a purchase of a new SIM which is unnecessary for me. How do I bypass the buy a SIM part?
