Secondary phone number

Hey there nils259,

Thanks for reaching out to the Apple Support Communities. If you're seeing the incorrect label for your second phone plan, check out the steps in the following resource that can help with changing the label: Using Dual SIM with an eSIM - Apple Support

Label your plans

After your second plan is activated, label your plans. For example, you can label one plan Business and the other plan Personal.

You'll use these labels when you choose which phone number to use for making or receiving calls and messages, to designate a number for cellular data, and to assign a number to your contacts so you know which number you will use.

If you change your mind later, you can change your labels by going to Settings, tapping either Cellular or Mobile Data, and then tapping the number whose label you want to change. Then tap Cellular Plan Label and select a new label or enter a custom label.

Let us know if that's able to help.

Have a great day!
