Switching SIM cards when getting a new iPhone is not necessary in order to transfer data. Thanks to modern technology, data can be transferred over a Wi-Fi network. However, eventually you will need to install the old SIM card in the new iPhone in order to setup the Messages and FaceTime apps that use your phone number.
The process of transferring data from an old iPhone to a new one is quite simple. First, you will need to back up the old iPhone. This can be done by connecting the device to a computer and using iTunes to create a backup. Alternatively, you can use iCloud to back up the data. Once the backup is complete, you can then restore the data to the new iPhone.
Once the data is transferred, you can then insert the old SIM card into the new iPhone. This will allow you to setup the Messages and FaceTime apps that use your phone number. You may also need to enter the PIN code associated with the SIM card in order to activate it.
In conclusion, switching SIM cards when getting a new iPhone is not necessary in order to transfer data. However, eventually you will need to install the old SIM card in the new iPhone in order to setup the Messages and FaceTime apps that use your phone number. The process of transferring data from an old iPhone to a new one is quite simple and can be done over a Wi-Fi network.
