Why Does My Samsung Galaxy Show “Unknown” for My Phone Number?

This issue often occurs when your SIM card fails to properly display the phone number associated with it.

This can happen due to various reasons like switching phones, a glitch in the SIM card settings, or even network issues.

Luckily, it’s something you can easily resolve with the help of an iPhone.

Requirements and Guides

You need the following items to get started:

• A SIM card that’s currently in your Samsung Galaxy device.
• An iPhone (borrowed or your own).
• Ensure that your SIM card has enough phone credit for the iMessage / FaceTime activation process.

Now, let’s walk through the process of fixing the “Unknown” number issue.

Eject the SIM Card from Your Samsung Galaxy Device

Use a SIM ejector tool or a paperclip to eject the SIM tray from your Samsung Galaxy Device.

Take the SIM card for the next step.

Check for Phone Credit

Make sure your SIM card has enough phone credit. This is important because the iPhone will need to activate iMessage and FaceTime, which requires a network connection and credit.

Borrow or Buy an iPhone

If you don’t already have an iPhone, you’ll need to borrow one from a friend or family member.

This part of the process only takes a few minutes, so it’s worth asking someone for a quick favor.

Insert the SIM Card into the iPhone

Once you have the iPhone, insert your SIM card.

Wait for it to detect the SIM card.

Wait for iMessage and FaceTime Activation

Allow the iPhone to go through its usual process of activating iMessage and FaceTime. This can take a few minutes.

Once the activation is complete, the iPhone will write the correct phone number to the SIM card.

Eject the SIM Card from the iPhone

Once the activation process is finished, eject the SIM card from the iPhone.

Insert the SIM Card Back into Your Samsung Galaxy Device

Now that the iPhone has written your phone number to the SIM card, it’s time to insert it back into your Galaxy phone.

Unlock the device and check if your number is now displayed correctly.

Check the Results

Your phone number should now appear properly under the “About phone” section or in messaging apps where it previously showed “Unknown.”

Why This Works

iPhones have a feature that writes the phone number onto the SIM card during iMessage and FaceTime activation.

This process updates the number linked to the SIM, solving the issue of Samsung Galaxy devices showing “Unknown” for the phone number.
