The problem is when the iPhone does not see (does not read) the SIM card is quite common today. Despite constant updates to iOS and the release of new devices from Apple, you are not safe from this error. If your iPhone (X, 8, 7, 6, 5, SE) has stopped seeing the SIM card, you will not be able to make calls, use the Internet, and indeed, you will be cut off from the outside world.
To notice this mistake is quite simple, because the iPhone will notify you about it: “The SIM card was not found or not installed” (the SIM card is invalid). You will also notice that in the left or right corner (depending on the version and iOS settings) of the screen, the signal reception bar is changed to “No SIM card” or “Search …”.
Fortunately, this error is quite easy to fix, below, we give the most common ways to do it!
Why doesn’t the iPhone see (read) the SIM card, what should I do?
The reasons why the iPhone does not see the SIM card may be different. In some cases, the problem may be associated with physical damage to the gadget, in others with a software malfunction. We tried to collect the most popular causes of this malfunction and, of course, wrote instructions for each of the items to help solve the problem.
Physical malfunction of the smartphone. List the entire list, which could cause this malfunction for a very long time, tedious and inappropriate.
However, the most popular reasons why iPhone does not read the SIM card lie on the surface. Physical malfunction can be caused by the fall of the smartphone from a large (although in the case of an iPhone and not large) height, moisture damage, incorrect installation of the tray with a SIM card or even its inoperability.
Software malfunction. Perhaps this is the second most common reason and it’s not about the crooked update released by the developer (although it happened). We are talking about a system error that may have occurred due to the incorrect completion of updates, installing applications or restoring a smartphone.
A malfunction associated with a SIM card or mobile operator. Perhaps this is the only problem in which the phone is not the culprit. Your SIM card may be physically damaged or completely blocked.
Also, the technical work of the telecom operator can serve as a source of the problem, but this rarely happens and all such subscribers are warned via SMS mailing.
What to do if the iPhone does not see the SIM card? Right, reinstall it!
Reinstalling a SIM card is the most commonplace, but quite logical idea. There is nothing complicated in reinstalling the SIM card, the only problem may arise with removing the tray, since not all users save the clip that comes with the smartphone. This does not matter, because you can always use a needle or any, quite thin and durable object. But be careful not to damage the SIM card tray and hands.
1. To reinstall the SIM card, take a paper clip (some iPhones come with a “SIM card eject tool”), straighten it and poke one end into the hole on the SIM card slot.
2. This will make the slot pop up. Make sure that the SIM card is inserted correctly and sits securely enough. Insert the tray back.
3. After a few seconds (in different cases, the time can vary from a few seconds to several minutes), the error “No SIM card” should appear, and then at the top of the screen the communication level and operator name will appear again.
4. If this does not happen, remove the SIM card completely.
5. Make sure that the card and slot are not dirty. If they are dirty, clean them. You can just blow it into the slot, but it’s better to take something more powerful, like a hairdryer (using cold mode) or a can of compressed air. Then reinstall the SIM card.
Does the iPhone still not read the sim card? Turn airplane mode on and off!
If you still have a mistake – “iPhone does not see the SIM card”, your next step is to turn airplane mode on and off. This may reset your iPhone’s cellular connection and fix the problem. To do this, swipe up at the bottom of the screen (or down from the top right on the iPhone X) to open the control panel. Click on the airplane icon to highlight it. So turns on flight mode.
Wait a couple of seconds and click on the icon again so that it no longer glows. Swipe the control panel down to hide it. Wait a couple of seconds to see if the problem has been resolved.
Reboot iPhone to fix communication error
If none of the above helps, restarting the iPhone is a universal solution for most problems, such as: the Internet is gone, the phone does not see another Bluetooth iPhone, the iPhone does not see (does not show) a SIM card. You will be surprised at the number of problems that a restart helps to resolve. There are two ways to reboot:
The first method is carried out by the interaction of the mechanical and software parts. As you understand, this is a soft reset.
The second method is carried out exclusively by buttons, using only the mechanical part.
How to make a soft reboot of the iPhone?
1. Press and hold the power button for a few seconds.
2. Wait for the inscription “Slide to Power Off” to appear on the screen.
3. Swipe the screen.
4. Press the button again to turn on the phone.
5. For identification, you will need to enter a password, even if you usually used a fingerprint for this.
How to hard reset the iPhone?
Making a hard reset of the smartphone is quite simple, but with the release of new smartphone series (starting with the iPhone 7), this method has been constantly changing.
In order to learn in detail how to restart any model of a smartphone from Apple, check out the article: How to restart iPhone X, 8, 7, 6, SE? or take a look at the screenshot attached below.
IPhone does not see a sim card? Try updating iOS!
If pulling out and reinstalling the SIM card is not successful, look for updates for iOS, the iPhone operating system. You will need to connect to Wi-Fi and have enough battery power to do this. Install any available updates and see if this solves the problem.
To update iOS, do the following:
1. Go to "Settings".
2. Open the "General" tab.
3. Select “Software Update” from the list.
4. If a new version is available, follow the on-screen instructions to download and install it later.
The iPhone does not see the SIM card – is the operator to blame?
Your phone number may not be valid. In order for your phone to be able to connect to the telephone network of the provider, you need a valid account. If your SIM card was blocked or your access to services was temporarily limited (for non-payment), a SIM card error may appear. We recommend contacting the operator for clarification.
Check for updates for carrier settings
Another reason why your iPhone does not see the SIM card (does not show the SIM card) may be that your telephone company has changed the settings at which the phone connects to their network, and you need to install them.
1. Go to “Settings” and select the “General” tab.
2. Tap in the "Other" (About) function.
3. If an update is available, a window will appear. Click on it and follow the on-screen instructions.
You can also get an update on the operator’s settings if you install a new SIM card that doesn’t connect to the network that the old one was connected to. When you do, you can download the new settings. The problem with the network connection should be fixed.
Try using a friend’s SIM card to connect to the network
If none of the tips above helped you, then try using the SIM card of your friend or relative. Perhaps it is in her, and not in the phone. Insert the card into the tray, if the error “No SIM card” (SIM card is invalid) disappears and everything works fine, then we determined the culprit – this is your SIM card.
Instead of visiting those. For support in the Apple Store, we recommend that you visit your carrier and tell him that you need a SIM card replacement for the iPhone. This is a quick process and you will receive a new one as soon as possible.
Similarly, you can try changing the phone by inserting a SIM card into another device. So you quickly determine why the iPhone does not see the SIM card.
Reset network settings if iPhone does not show SIM card
A rather unpleasant point is the reset of network settings. Why? As soon as you reset the settings, passwords from all previously saved WiFi networks will be reset along with them.
To reset network settings:
1. Go to "Settings".
2. Select the "General" section.
3. Then select “Reset”.
4. Select “Reset Network Settings” and confirm.
This will restore the network configuration to the factory default settings. This will help you troubleshoot software problems in background processes that are responsible for managing how your iPhone connects to cellular and other networks.
Update your operator’s wireless settings using iTunes on your PC.
Connect the phone to the computer (you can also use a friend’s computer). We recommend using iTunes, because before updating the phone, iTunes will automatically check the smartphone for updates to the provider’s settings and, if there are any, will suggest you install them.
If all else fails, how to be?
If none of the tips helped, the problem most likely is the physical malfunction of the iPhone. You can solve it yourself, but for this you need to have certain skills and special tools.
Therefore, the most reliable way will be to contact the service, having given the smartphone for repair.
Carry out a gadget repair yourself
Let’s say right away, using this method, without having certain skills, you run the risk of aggravating the situation. If you consciously take risks, the first thing you need to do is get a certain set of tools.
This set includes several brackets (in order to pry off the screen), a special screwdriver with various tips and a suction cup. In different sets, sets may vary, it all depends on the manufacturer.
1. To begin, using special tools, disconnect the screen of your iPhone.
2. Then disconnect the battery by unscrewing the special mount and disconnecting the cable.
3. Inspect the sim receiver for damage. If there are any (for example, the contact is removed), carefully correct it.
4. Assemble the smartphone (start the assembly from the top of the screen where the front camera and speaker are located).
Standard methods could not solve the problem. I had to.
