4. Reset the network settings

If you’re still seeing a card error message, try resetting your network connection settings to clear your Wi-Fi passwords and saved networks. Don’t worry, this won’t delete any apps, photos, or contacts but it may resolve any network issues. Here’s how to do it:

1. Open Settings and tap System > Advanced > Reset options.
2. Then, tap Reset Wi-Fi, mobile & Bluetooth, or if you have a Samsung phone, tap General Management > Reset > then Reset Network Settings. 
3. Tap Reset Settings and enter your passcode or password. 
4. Tap Reset Settings, then Reset. 

5. Contact your carrier

Still having trouble? You may need to contact your cell phone carrier to check your service and possibly get a new SIM card. 

6. Restore your phone to factory settings

A factory reset may fix your problem, but it should be a last resort. Before you try this option, make sure to back up your data—if you don’t, you may lose it. Then, follow these steps to factory reset your device.
