If you put your boyfriend's SIM card in your phone, it will essentially transfer his phone number and mobile carrier account to your phone. This means that you will be able to make calls, send texts, and use data under his phone number and account.

However, remember that some services or features may only work properly if the SIM card is compatible with your phone or carrier. It is best to consult with your mobile carrier or your boyfriend before making any changes to ensure that both devices are compatible and properly configured.

A SIM card is only the key to the cellular network, not to storing data. If you want to access the data, you might not be able to achieve it. After inserting your boyfriend's SIM card into your phone, you can make and receive calls and messages from now on, but you cannot access his message history or call logs since this information is on the old phone, not on the SIM card.

If you want to give your phone to your boyfriend, there is one way to transfer all the data from the old phone to the current phone. Let EaseUS MobiMover be your great helper, which can transfer everything from iPhone to iPhone, including pictures, text messages, WhatsApp messages, contacts, audio files, etc. EaseUS MobiMover supports both iOS and Android, and you can download it from your Windows or macOS computer.

Step 1. Connect both your phones to the computer and launch EaseUS MobiMover.

Step 2. Choose Phone to Phone > Select the data > Click Transfer.

Step 3. Then, it will start the data transfer process. Do not use your phones until the data transfer is completed.
