5 Ways to Fix SIM Card Problems on iPhone 13
Fix #1. Check for activation error
As we mentioned, the iPhone 13 is in unprecedented demand in the United States. With so many devices active at the same time, your network service provider may be having difficulty activating them in time. This can lead to activation errors, which usually resolve automatically after a few hours. As these problems are operator-dependent, you – the user – can’t do much to fix them yourself. If your iPhone 13 doesn’t turn on automatically, contact your network service provider. They would be able to tell you what the problem is and, with luck, give you the correct solution.
Fix #2. Check for a carrier settings update
when a new phone is released, service providers often distribute updates to their network settings. When this mismatch happens, you may get the error message ‘Invalid SIM card’ or ‘No SIM card’. To make sure there are no pending updates for your device, all you need to do is go to Settings, tap ‘General’ and open ‘About’. Updates, if available, would be installed immediately.
Fix #3. The last line is no longer available iPhone 13
The ‘Last line is no longer available’ error seems to pop. up when a user is about to make a call on their iPhone 13 when they turn it on for the first time. Based on previous instances, this issue appears to be a bug that is somehow related to e-SIM functionality on some newer iPhones. An e-SIM is a digital SIM that enables dual-SIM option on newer iPhone models such as iPhone 13, iPhone 12, iPhone 11, iPhone XR and iPhone XS / Max. Users experiencing the ‘Last line is no longer available’ error report that they are alerted to the error as soon as they are about to make a call from their default line through the Phone recent application logs. The default line is the SIM you prefer to use to make calls and send messages to people you haven’t saved as contacts.
Fix #4. Reset Network Settings
If switching Airplane Mode and resetting the device does not work, you should consider resetting the network settings. First, go to Settings and tap ‘General’. Now go to ‘Reset’ and tap ‘Reset network settings’. Confirm your action and restart the device.
Fix #5. Reinsert the SIM card
A misplaced SIM card can make life extremely difficult. Dropped calls, no coverage and activation errors are caused by them. So it’s always a good idea to make sure the card is seated correctly. Simply remove your SIM using the SIM eject tool, remove the SIM card, clean the card with a dry cotton/microfiber cloth and replace. Reinsert your SIM to see if it fixed the problem.
