If you put someone else's SIM card in your iPhone, it will change the device's phone number to the one associated with that SIM card. Your contacts, apps, and data will remain unchanged, but you won't be able to use your original phone number until you reinsert your original SIM card. Ensure the iPhone is unlocked or compatible with the other SIM card's network. No personal data from the iPhone will transfer to the new SIM card.
