If your new phone takes a different sized SIM you’ll need to keep the new SIM in your new device and Text SWAP to 23424 from your original SIM card.

If your new phone takes the same SIM card size as your current SIM card, you don’t need to do a SIM swap. Just take your current SIM card and put it in your new phone.
