If your phone is saying the SIM not valid, try the steps outlined in this article.
Get help activating your iPhone - Apple Support
- If your carrier provided a SIM card, make sure it's in your iPhone.
- Restart the iPhone.
- Try to reach the activation server another way, then try to activate.
- Try connecting to a known-good Wi-Fi network if you can't activate using a cellular data connection.
- Try connecting to iTunes if you can't activate using Wi-Fi.
- Restore the iPhone.
- Check the system status for iOS Device Activation. If the iOS Device Activation status isn't green, try activating your iPhone later.
If you receive an alert message when you try to activate your iPhone, place the iPhone in recovery mode and perform a restore. If you still can't complete the setup assistant due to an activation error, contact Apple for assistance.
If you're asked to enter a password to proceed with activating the iPhone, Activation Lock might be enabled as part of Find my iPhone.
Thank you for visiting Apple Support Communities.

If your phone is hacked to unlock it, then if you reset, restore or update it, then it will revert to being locked again, so your sim card will come up as being invalid.
Contact your carrier and get your phone unlocked properly through the carrier and without hacking.
