Are you getting an error when trying to insert the SIM card into your iPhone ? The “Invalid SIM card” message on iPhones or iPads is a very common error that affects many users. There’s no specific cause, as it can be due to a variety of factors, from internal issues with the phone to problems with your carrier. In this post, we’ll show you possible scenarios and different solutions to this message on the iPhone.
All iPhone models are compatible with this tutorial. Therefore, you can follow the steps on the iPhone 6 and 6s (including the Plus models), iPhone 7, iPhone 8 and 8 Plus, iPhone X, Xr, Xs, and Xs Max, or even the new iPhone 11, 11 Pro, and 11 Pro Max. However, depending on the iOS version, the settings may be in a different location. In this case, I followed the steps on iOS 13, and versions like iOS 12 or even iOS 11 have the same settings.
First, check if there’s a software update available. If your SIM is new, it may need the latest version of iOS. To update, go to Settings > General > Software Update . Second, restart your iPhone or iPad. Simply hold down the Power button and Volume Up and slide to power off. Then, press the Power button until the screen appears. Finally, re-enter your SIM PIN and check if the message appears. Often, it’s necessary to restart your device for the carrier settings to activate and everything to work correctly.
Remove the SIM from the tray and reinsert it . You may have inserted the SIM card incorrectly, causing the system to not detect it. Check if the pins on the bottom are in good condition. Also, check if you’re using any type of adapter or if it has an irregular cutout. In this case, it’s best to order a new card.
SIM card not valid with Vodafone, Movistar, Orange or other operators
This message may appear due to issues with your carrier. It could be because your SIM card isn’t yet active, or your carrier hasn’t yet connected your mobile line. To do this, contact your carrier’s customer service and verify that your line or SIM card is already activated. If you’re using an eSIM, you’ll likely need to call your carrier to provide the eSIM number and have them activate your line.
Check that the network settings match your carrier’s settings and are up to date. If you’ve inserted a new SIM from another company, the new settings may not have been downloaded. This creates a system conflict that prevents the SIM card from being recognized on the iPhone. To check if the network settings match your carrier’s, go to Settings > About. There you’ll see the network and carrier information. If you’re with Vodafone, it should say ‘Vodafone ES’. If you have an MVNO, such as O2, Movistar will likely appear. In any case, you should also check if there are carrier updates available. These appear in System Settings, under Information. If there’s no warning, it means no updates are available.
Reset your device to factory settings. Don’t forget to back up your data first. If the message persists after following these steps, check if it also appears with other cards. If you don’t have one, take it to your carrier and ask them to insert one to see if it’s a device error. As a last resort, take your iPhone to a service center, as it could be a hardware issue.
