If you’re not changing carriers most of the time you’re able to swap your Sim from one phone to the other (unless you were using the eSim feature) every time I upgrade I can swap the sim or choose to use the new sim (which usually I choose to use the new sim because well new phone new sim. If the device does not activate on your old sim reach out to your carrier to ensure the proper sim is active.
