“SIM Not Provisioned”
What This Means (In Plain English)

- •Moving a SIM card from an old phone to a new one without activating it
- •A damaged or very old SIM card
- •Account issues with your mobile carrier
How to Fix It — Step by Step
- 1
Turn your iPhone off completely, then turn it back on.
- 2
Remove the SIM card tray using a SIM ejector tool or a straightened paperclip.
- 3
Take out the SIM card, check it for damage, and place it back in carefully.
- 4
Make sure the SIM card is sitting flat and properly aligned in the tray.
- 5
Push the tray back in gently until it clicks.

If the error continues, call your mobile carrier (e.g., AT&T, Verizon, T-Mobile) and ask them to reprovision your SIM.
- 7
Your carrier may need to send you a new SIM card — this is usually free.
