I recently upgraded my phone to a pixel 7. It came in the mail with a new sim card. I thought there was some sort of process to follow where my new sim card supersedes the old one, but it looks like the new one just doesn’t work and I just transferred my old sim card to the new phone and it worked.
Is it okay if I just throw out the new sim card? Why would they send me an extra sim card? For the plastic size adapters?
