Part 3: What to Do If Your iPhone 13 Says No SIM Card?

Now that you know what factors cause the SIM failure on iPhone 13, you can easily avoid them to save yourself from the problem. If not that, then you can detect the root of the problem. Is this all you will learn about SIM failure? No. The section coming below will share different fixes that you can follow to resolve the trouble of SIM card failure.

1. Check if SIM Malfunctions

We usually purchase one SIM and then use it for the rest of our life. Not realizing the fact that SIM gets old and old SIM is an expert for throwing weird and unexplained errors. For this reason, if your SIM card fails on iPhone 13, then you must try to use it on some other device and check if it is working properly or not.

2. Check your Activation Error

iPhone 13 has a great demand. In case your SIM card is not working, you should wait and check for an activation error. This is because your service provider might have a lot to handle. As a greater number of devices are going live simultaneously, it's hard to activate them all. Since this problem is carrier-dependent, nothing much could be done except for waiting.

3. Reset SIM Card

Among the common reasons that cause SIM failure, one is when the SIM is poorly seated on the SIM card. The best thing to do whenever you face a coverage problem, dropping calls, or activation error, simply take out the SIM card with a card ejector. Clean the card with a dry microfiber cloth and then reinsert and reset the card on the tray. Check your phone to see if the problem has been resolved or not.

4. Play with Airplane Mode Settings

This might sound strange, but most iPhone users have tried this, and it works. Turning off the Airplane mode and then turning back on actually does the job. If you have never used the Airplane mode before, then take guidance from the steps below.

Step 1: To enable the Airplane mode, you need to access the ‘Control Centre.' For that, from the top right corner of the screen, swipe down. From the Control Centre, locate the ‘Airplane Mode’ icon and click on it to enable it.

Step 2: After a few seconds of enabling it, you can now disable it in the same way.

7. Check the Network Coverage

On iPhone 13, no matter how good or poor your network, the antenna bands always show a steady connection. It is tough to use cellular services like calling and texting with poor coverage.
