To switch SIM card from Android to iPhone, you physically move your existing nano-SIM card from one device to the other to keep your phone number and service, but you must first check compatibility because US iPhone 14 and later models are eSIM only and do not accept a physical SIM card. Before you begin, confirm that your Android phone uses a nano-SIM card, which is the smallest SIM size and the only type that fits an iPhone's SIM tray; if you are unsure where to find it, see locating the SIM card on Android phones before proceeding. If you need to preserve media during this transition, you can also handle transferring photos from iPhone without SIM card.
Before you switch your SIM card from Android to iPhone: Critical compatibility check
Not all iPhone models have a SIM tray. Physical SIM cards are not supported on iPhone 14 and later models purchased in the United States; these devices support eSIM only. If your iPhone model does not have a SIM tray, it supports eSIM only. For all other iPhone models, confirm that your Android SIM card is a nano-SIM. The SIM tray's shape and orientation depend on the iPhone model and your country or region. In Hong Kong and Macao, certain iPhone models feature Dual SIM with two nano-SIM cards. In China mainland, iPhone 17e can be activated with either an eSIM or a physical nano-SIM.
How to remove the SIM card from your Android phone
- Power off your Android phone to minimize the risk of disrupting the device's functionality.
- Locate the SIM card slot on your Android phone. Depending on the device model, it may be on the side, top, or back.
- Insert a SIM card removal tool or a small paperclip into the pinhole next to the SIM card slot. Apply light pressure until the SIM card tray is partially ejected.
- Carefully pull the tray out from the phone using your fingers.
- Remove the nano-SIM card from the tray by gently sliding it out. Handle it delicately to avoid damaging the card's circuitry or contacts.
- Inspect the SIM card and tray for any signs of damage or debris.
How to insert the SIM card into your iPhone
Understanding the correct orientation for inserting a SIM card is crucial to avoid damaging the tray or the card. The angled corner of the nano-SIM card determines the correct orientation in the tray.
- Power off your iPhone before initiating the SIM card installation.
- Locate the SIM tray. For iPhone 12, 13, 14, 15, 16, and 17 series models, the SIM tray is on the left side. For iPhone 11, XS, and XS Max models, the SIM tray is on the right side.
- Insert a SIM eject tool or a straightened paper clip into the small hole of the SIM tray and push in towards the iPhone to eject the tray.
- Remove the tray from the iPhone.
- Place the nano-SIM card in the tray, ensuring the angled corner matches the tray's shape for correct orientation.
- Insert the tray back into the iPhone until it sits flush with the device's exterior.
Activate your iPhone with the new SIM card
- Power on your iPhone. The device will detect the new SIM card and begin the activation process.
- If a PIN was previously set on the SIM, carefully enter the PIN when prompted. Incorrectly guessing a SIM PIN can permanently lock your SIM, so be certain of the correct PIN before entering it.
- Follow the on-screen setup prompts, which may include connecting to a Wi-Fi network to expedite activation.
- Wait for the activation to complete. Your iPhone will display a confirmation message when the new SIM card is successfully recognized and integrated.
How to transfer an eSIM from Android to iPhone
For eSIM-only iPhones or if you prefer to use an eSIM, you can transfer your cellular plan directly from your Android device using the built-in transfer feature. This requires iOS 26 on the iPhone and Android 16 or later on the Android smartphone. Both devices must be connected to a Wi-Fi network and have Bluetooth enabled.
- Open the Settings app on your iPhone.
- Tap "Set Up Cellular" and then "Transfer from Android". If you already have another SIM on your iPhone, go to Settings > Cellular, tap "Add eSIM", and then tap "Transfer from Android".
- A QR code will be generated on your iPhone. Use your Android camera to scan the QR code on your iPhone.
- On your Android, select the phone number to transfer and tap "Transfer".
- If asked, tap "Yes" to use the transferred SIM as your primary eSIM.
- If you cannot scan the QR code, on your iPhone select "Other Options" under the QR code. On your Android, open Settings > Google services > All services > Pair with iPhone or iPad > Transfer eSIM. Enter the session ID and pairing code displayed on your iPhone and tap "Next". Select the phone number to transfer and tap "Transfer".
- When the transfer is complete, tap "Done" on your iPhone and "OK" on your Android.
Not all carriers and smartphone manufacturers support the direct eSIM transfer feature. You may need to contact your carrier to transfer your eSIM via eSIM Carrier Activation or by providing a QR code. Alternatively, you can convert a physical SIM to an eSIM on a supported iPhone model by going to Settings > Cellular, tapping "Set Up Cellular" or "Add eSIM", choosing the phone number with a physical SIM, and tapping "Convert to eSIM".
Troubleshooting common SIM card switch problems
No SIM detected
If your iPhone fails to recognize the new SIM card, first ensure the SIM card is properly aligned in the tray and securely inserted. Restart your iPhone to allow the device to re-detect the SIM card.
No Service
If your iPhone displays "No Service" after SIM card insertion, check the signal strength in different locations to rule out network coverage issues. Ensure the SIM card is not damaged and that network settings are correctly configured. Resetting network settings on the iPhone may help resolve connectivity issues.
Activation failures
If the activation process fails, verify that the SIM card is compatible with your iPhone model and that the cellular plan associated with the SIM card is active and in good standing. Contact your cellular service provider for assistance.
Incompatible SIM card
If the SIM card from your Android device is not compatible with your new iPhone, obtain a compatible SIM card from your cellular service provider and begin the SIM card switching process again.
