What is a SIM Card?

It lets you make and receive calls, send and receive messages, access cellular data, and connect to your carrier’s mobile network. However, such operations essentially stop when a SIM card is defective or isn’t recognised.

Nevertheless, they are incredibly informational and hence powerful. As a result, a variety of situations might make your iPhone display the “Invalid SIM” notification. These may consist of:

  • An improperly positioned SIM card or tray
  • a malfunctioning system

Working through the fastest potential remedies first will make dealing with an invalid SIM card easier, therefore we advise doing the below troubleshooting procedures in that order.

Verify That Your Plan Is Active With Your Carrier

Even though it might seem obvious, do you presently have a plan with a cellular carrier? If not, you won’t be able to use a mobile network to send messages, make calls, or do any other actions.

Similar to the last example, if it has been a while since you used the aforementioned SIM card or paid your mobile bill, your carrier may have temporarily or permanently cancelled your number.

Make sure your phone number is registered and in good standing by checking your carrier’s app or getting in touch with them directly.

Enable and disable Airplane Mode

One of the quickest fixes for a variety of network-related issues, including a finicky SIM card, is toggling your iPhone’s cellular data. Simply launch Control Center and toggle Airplane Mode on and off to complete this quickly.

Restart Your iPhone

Try turning it off and back on again, a wise guy once advised me. Sometimes a simple software issue might make your SIM card seem invalid.

This tried-and-true troubleshooting advice may be all your iPhone needs to detect your SIM card, regardless of whether you need to force restart, just restart, hard reset, or soft reset.

Press and hold the Volume Down and right Side keys simultaneously until you see the Power Off slider to restart an iPhone 11, iPhone XR/XS, or iPhone X.

Once your phone has finished shutting down, drag the slider again to turn your iPhone back on.

Press and hold the Sleep/Wake button (found on the top for the first-generation iPhone SE, iPhone 5, and previous iPhones and on the right side for the most current models) until the Power Off slider displays to restart an iPhone SE, iPhone 8, iPhone 7, iPhone 6, iPhone 5, or earlier.

Contact Apple Support

The cost of a replacement SIM card might vary greatly depending on your cell plan and the carrier you select.

Occasionally, buying a brand-new iPhone could be the best option, especially if AppleCare still protects the one you have.

Update the iOS

On occasion, a software bug might make it seem as though your SIM card is invalid or that your iPhone is missing its SIM card entirely.

Fortunately, Apple frequently releases a new version as soon as it discovers these problematic upgrades. Go to Settings > General > Software Update, then choose Download and Install if required, to manually check for iOS updates.

Before actually installing any updates, make sure to make a backup of your iPhone just in case.

By neglecting these updates, you risk your SIM card malfunctioning and missing out on the newest features offered by your cell operator.

Remove and Reinsert Your SIM Card and Tray

Nearly everything an iPhone needs to operate properly depends on the delicate balancing act of a SIM card in its tray.

It’s conceivable that the SIM card has been jostled out of place or has sustained other damage if your phone recently took a crash or if the SIM tray was hastily inserted into the slot.

Reset Your Network Settings

A software flaw in your phone’s network settings may be the cause of the invalid SIM card warning if you’re still experiencing problems with it. WiFi, Bluetooth, cellphone data, and any VPN you might have are all covered by this.

It’s reasonable to assume that your SIM card is the problem and that it’s time to get a new one if the “No SIM” or “Invalid SIM” issue disappears. If not, your phone is probably the issue. Fortunately, you have one more option to explore before giving up and raising the white flag of surrender.
