My iPhone says no SIM card.
Hi. My phone says no SIM card. I cannot send nor retrieve phone calls nor messages. How do I rectify this?
- Question from Apple Community
When you need to make calls or send messages, having a SIM card in your iPhone is essential. However, sometimes you might receive a notification saying "No SIM Card Installed." This can be quite frustrating, but don't worry—this article will guide you on how to quickly solve this issue.
When you encounter a “No SIM” alert or a similar notification on your iPhone, it indicates an issue with your SIM (Subscriber Identity Module) card. The SIM is a small plastic chip that fits into your device, storing essential data and enabling you to make calls and access mobile internet, among other functions.
If your iPhone displays “No SIM,” the problem could be due to a damaged or dirty SIM card, software glitches, or the need to update your carrier settings.
Here we offer some useful ways to help you. Hope you can fix the issue right now!
When the issue occurs, you can try to restart your device first.
For iPhone X or later: Press and hold either volume button and the side button simultaneously until the power-off slider appears > Drag the power-off slider to the right to turn off your device.
For iPhone 6/7/8 or SE(2nd or 3rd generation): Press and hold the side button until the power-off slider appears on the screen > Drag the slider to the right to power off your iPhone.
For iPhone SE (1st generation), 5, or earlier: Press and hold the top button > When the power-off slider appears, drag the slider to turn off the device.
After that, press and hold the side/top button until you see the Apple logo to turn on your iPhone. Then you can check your SIM to see if the problem is solved.
If your iOS system is outdated, your iPhone can always cause various iPhone issues, so you can update the software on iPhone to try to fix it. Just go to Settings > General > Choose Software Update. If there is any update available, click Download and Install to make it.
If your iPhone is updated, take a moment to examine the SIM card and the card slot for any dirt or damage. Ensure that the SIM is properly aligned when you place it back in the tray.
Step 1. If the SIM card is dirty, carefully clean it by wiping it with a microfiber cloth or a cotton swab moistened with a 50/50 mixture of water and alcohol. Allow it to dry completely before reinserting it into the tray.
Step 2. If the SIM card is not correctly seated, follow the steps to remove and reinsert it properly.
Step 3. If your SIM card is damaged, reach out to your carrier for a replacement.
Step 4. If the tray is damaged, you will need to have your iPhone repaired.
Once the process is finished, you can check for the carrier settings: Go to Settings > General > About. If there’s an available update, follow the prompts to proceed with the update.
If your issue is still unresolved, please contact your wireless carrier to confirm that you have an active plan. Additionally, if your device uses an eSIM instead of a physical SIM card, you will need to reach out to your carrier to address any error messages.
If all ways can't work, as a last resort, you can reset your iPhone to factory settings. Note that this will erase all data on your device, so make sure to backup any important information on iPhone first.
You can perform a factory reset through your iPhone's settings: Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
