Do you own an iPhone? If yes, have you come across a pop up saying “Invalid SIM,” which means you can’t send text messages or make phone calls. We’ll look into this SIM failure iPhone issue and how the problem can be fixed.
The iPhone may issue the “Invalid SIM” error because of a software issue. Meaning, the SIM card may be wrongly placed, or the SIM card needs to be replaced by the wireless carrier.
Below are the steps on how to fix the “Invalid SIM” error:
When an iPhone SIM card error pops up, you should turn airplane mode On and Off. After turning the Airplane mode On, the iPhone will disconnect from the wireless and cellular networks.
Open the settings and click next on the switch to see the Airplane Mode interface. After a few seconds, turn the switch Off. See if that hack will rectify the issues
Check whether your iPhone has the carrier settings update. Apple usually uses the carrier settings to ensure your phone can easily connect to the cellular towers.
To access the carrier settings:
If a pop-up fails to appear, it means the carrier settings are not available.
At times an iPhone says no SIM since there is a minor software issue. As you restart your phone, all programs are shut down naturally, which means you’ll have a fresh start as you turn the phone back ON. Meaning, if there was an issue with software hanging, a restart will jumpstart the software afresh.
When your iPhone’s software is out of date, you may experience an iPhone SIM card problem. The developers at Apple usually release new iOS updates as they introduce new features and fix software bugs. To update the iOS, go to Settings > General > Software Update. If a pop-up appears, click Update and install.
But, if your pockets are warm and you’re sure an update is what you need, why don’t you sell your iPhone for top dollar and get the latest one with updated software?
We have managed to look into how you should troubleshoot your iPhone in the steps above. We can now initiate a discussion about why the iPhone won’t read SIM Card.
If you dropped your phone recently, the SIM card might have been displaced from its initial position. You can eject the SIM card and place it back in.
The SIM card tray is present on the right edge of the phone. For the earlier versions of the iPhone, the SIM card tray is present at the device’s top.
A paper clip or SIM card ejector tool is used to press down the small circle around the SIM card tray. You can apply some pressure to ensure the SIM card tray has been ejected.
Ensure the SIM card is well-positioned before reinserting the tray back to your phone.
If the “Invalid SIM” error still appears, you should try out the other troubleshooting steps that will be discussed below.
This step entails determining whether you are dealing with a SIM card or iPhone issue. You can ask your friend for the SIM card and insert it into the iPhone. Does the “Invalid SIM” error still appear?
If the iPhone brings about the invalid SIM error again, it means the device has an issue. If the problem faded away after you inserted another SIM card, it means your SIM card has an issue, and the iPhone is working well.
To solve the SIM card issue, you should contact your wireless carrier. You can check the customer support contacts on the internet.
The network settings on your iPhone include Bluetooth, Wi-Fi, VPN, and cellular settings. An iPhone can say “Invalid SIM” if a software error is present in the cellular settings. Unfortunately, such issues can be hard to pinpoint, which means you should reset all the network settings on your iPhone.
Note: Ensure you have jotted down all the Wi-Fi passwords as you reset the network settings since you’ll have to re-enter them as you reset the iPhone.
Use the following steps to reset the network settings- settings> General> Reset> Reset Network Settings. You’ll have to key in the iPhone passcode as you confirm the reset.
If the “Invalid SIM” error persists even after resetting the network settings, you should contact Apple or your wireless carrier. For SIM card issues, it is advisable to get in touch with the wireless carrier first since they can fix the issue. In most cases, you only need a new SIM Card.
You can visit the wireless carrier’s local retail store or even contact them through the customer representative contacts.
If you’re tired of the “Invalid SIM” issue, you can consider moving to a new wireless carrier. Before doing so, compare the plans provided by different wireless carriers.
As discussed above, there are different ways to troubleshoot and fix the “Invalid SIM” issue. After fixing the error, you can use cellular data and make calls. If you can’t fix the issue, feel free to visit one of our stores for a free diagnosis.
If the SIM card were the main issue, the iPhone wouldn’t showcase the “Invalid SIM” error after inserting a new one. However, if it’s a software issue, the error will persist.
No, you don’t need a new SIM Card.
No, not any SIM Card can be used on an iPhone. The frequency bandwidths of the wireless carrier should match those of the iPhone.
