The story goes something like this: You recently bought a refurbished iPhone and the description of the online market (or the person who sold it to you, local retailer or personal transaction) promised the iPhone is Network Unlocked. But as soon as you inserted your Carrier’s SIM card you got the ”iPhone SIM not supported” message.
Depending on the iOS version this message could also be:
- No SIM card Installed
- Invalid SIM
So, what can you do when the SIM card inserted in this iPhone does not appear to be supported?

How to fix the ”iPhone SIM not Supported” problem
First of all, don’t panic! You have to determine if the ”iPhone SIM not Supported” error is a Software, Hardware or Network Lock issue!
Before you try to SIM unlock this iPhone, check all the ”Fix Invalid SIM” tips below. Maybe one of them will bypass the SIM Not Supported issue on your iPhone.
- Make sure that the SIM card you inserted in the iPhone is still under an active contract with your Mobile Network.
- Contact your Cellular Network and check for activation or network issues. Maybe you need to replace your current SIM card.
- Update your iPhone to the latest iOS version.
- Try turning airplane mode on and off.
- Restart the iPhone.
- Go to iOS Settings > General > About and check if there is a Carrier settings update.
- Remove the SIM card from the SIM card tray and then put it back. Make sure that the SIM tray closes properly. Sometimes using a SIM tray from a different iPhone model or another smartphone manufacturer creates this ”invalid SIM” problem.
- Try using another SIM card. Maybe your SIM card is damaged! After all, SIM card not installed alerts are displayed when a SIM card is damaged, locked, or missing.
- If another SIM card was used with this iPhone until recently and even if the SIM card’s contract has expired, the iPhone might need this specific SIM card in order to get activated.
- In case you are using a cellular data connection, try to connect to a Wi-Fi network (that you know that is reliable) instead. If the Wi-Fi connection fails, try connecting to iTunes.
- If you’re using iTunes to activate your iPhone, make sure that iTunes is updated to the latest version.
- Use recovery mode and restore the iPhone.
