No SIM error messages on your iPhone can be quite annoying to deal with, especially if you’re trying to make or receive calls and text messages.

Luckily, there are some simple fixes you can try out to fix the issue, so you can get back to using your iPhone again quickly and easily.

The following article provides information on how to fix no sim on iPhone 7 and how to fix no sim on iPhone 6s as well as how to fix no sim on any other iPhone models.

Apple explains what No SIM means

In order for your iPhone to work, it must have a SIM (Subscriber Identity Module) card.

This is what connects your phone to your carrier’s network and gives you access to services like cellular data and calling/texting.

Occasionally, there may be an issue with no SIM showing up. The error means that there is no active voice or data plan for your device and you will not be able to make calls or send text messages without first activating your service through iTunes.

Fortunately, Apple has designed a workaround you can use in order to troubleshoot and fix issues with no SIM showing up on your iPhone.

How to Fix No SIM on iPhone

Below are tips on how you can easily fix the No Sim Error on your iPhone:

Update iOS, Preferably Using iTunes

If you’re using an Apple device, it’s important that you stay up-to-date with your operating system.

Updating through iTunes (this is only available for iPhones, iPads, and iPods) is incredibly easy: Simply connect your device to your computer with a USB cable and click Check for Update.

You may need to download and install iTunes first; it’s always good practice to download updates directly from their source.

You may also be prompted by iTunes itself when new updates are available.

Restart your phone

If you just restored your phone or it’s been acting weird, it could be that there’s an issue with your SIM card. Restarting your phone is usually an easy fix for a host of problems.

To restart your phone, press and hold down both the Sleep/Wake button and Home button until you see a slide to power off or slide to unlock.

Then drag the slider from left to right. After you reboot, check to see if you have cell service.

Try using Another Sim Card

If you get a no sim error, it’s because your phone is trying to connect to your carrier. To troubleshoot, try connecting your phone with another sim card (provided by someone who is currently using their cell).

If that doesn’t work, reset all network settings: Settings > General > Reset > Reset Network Settings.

Another option is to restore all settings: Settings > General > Reset > Erase All Content and Settings.

In these cases, you may have to enter your Apple ID/iCloud login information again as well as re-enter any wifi passwords. Hopefully, that fixes things!

Turn Your iPhone Off And Back On Again

The easiest way to troubleshoot any electronic device is by turning it off and then back on again. It’s simple, but more often than not it works!

If you suspect your phone has stopped reading your SIM card for some reason, try turning it off and restarting. This clears the memory and resets everything—in most cases, that’s all you need.

Restart your carrier settings

How to Fix No SIM on iPhone

A simple fix for this issue can be restarting your carrier settings. Go to Settings > General > Reset and tap Reset Network Settings.

This will clear out any possible problems that are causing your phone not to receive network signals properly, so try it before you go any further.

If you aren’t sure how to get there, don’t panic; we’ll show you exactly where in just a minute.

Restore your phone from backup

If you’re getting an error code that says No SIM, there are some things you can do to try and fix it. First, restore your phone from backup (located in Settings > General > Reset > Erase All Content and Settings).

This will wipe everything off your phone, but restoring from backup will reinstall all of your software, settings, and data.

Also, if you have to Find My iPhone enabled on your device, disable it. Once that is complete, put your device into DFU mode (this is accomplished by holding down both home and power buttons for about 10 seconds), select iTunes as Device Firmware Update and let iTunes complete what it needs to do.

Reinsert The SIM Tray

The no-SIM error is usually caused by a loose connection between your phone and its antenna. The most common way to fix it is with a quick reset: Pull out your SIM tray, wait for 10 seconds, then put it back in.

To pull out your tray you need either an iFixit ejector tool or an unbent paperclip. This step doesn’t involve any actual repairs but does solve about 90% of no-SIM errors we see.

If you’ve already followed these steps and are still getting a no service error then move on to another option.
