Sim Card

Help me with this. Why can’t they create a sim card that can store your numbers the same way they do on your phone? If you have multiple numbers for someone stored under their name, a sim card has to separate them into different entries.

So when you buy a new phone, you have to transfer them to the sim card which separates multiple numbers into different entries. Then you have to reenter your phone numbers to get them back to where you started with your old one. Ugh.
