Fixing SMARTY SIM Detection on iPhone
Fully power off your iPhone. Remove the SIM tray using the ejector pin. Take out the SMARTY SIM, check it for physical damage, then reinsert it firmly in the correct orientation. Power on and wait 2 minutes.
Use a dry, lint-free cloth to gently wipe the gold contacts on the SIM card. Oxidisation and dust on the contacts are a common cause of intermittent SIM detection failure.
If your iPhone has a dual SIM slot, move the SMARTY SIM to the other slot. This tests whether the original slot has a hardware fault.
Insert a different SIM into your iPhone. If the other SIM is detected, the problem is with your SMARTY SIM card — request a free replacement from SMARTY on smarty.co.uk live chat.
Insert your SMARTY SIM into another device. If it is not detected there either, the SIM has failed and needs replacement. Call smarty.co.uk live chat to arrange a free replacement SIM.
Go to Settings → About Phone → System Updates. Install any pending updates — firmware updates sometimes include fixes for SIM detection issues.
Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. This clears all network state and forces your iPhone to re-detect the SMARTY SIM from scratch. Restart after resetting.

Frequently Asked Questions
Why does my iPhone say No SIM with SMARTY?
No SIM detected usually means the SIM is not seated correctly, the contacts are dirty, or the SIM has failed. Start by powering off, removing and reinserting the SIM. If the problem persists, test the SMARTY SIM in another device to determine if the SIM or the iPhone is at fault.
How do I get a replacement SMARTY SIM?
Contact SMARTY on smarty.co.uk live chat or visit a SMARTY store. SIM replacements are usually free if your original SIM has failed. Your number and account transfer automatically to the new SIM within a few hours of activation.
Can a software update cause SIM not detected?
Yes — some firmware updates change modem driver settings that affect SIM detection. If the issue started after an update, try removing and reinserting the SIM after the update completes, or perform a network settings reset at Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
