Fixing Sky Mobile SIM Detection on OnePlus
Fully power off your OnePlus. Remove the SIM tray using the ejector pin. Take out the Sky Mobile 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 OnePlus has a dual SIM slot, move the Sky Mobile SIM to the other slot. This tests whether the original slot has a hardware fault.
Insert a different SIM into your OnePlus. If the other SIM is detected, the problem is with your Sky Mobile SIM card — request a free replacement from Sky Mobile on 0333 759 0000.
Insert your Sky Mobile SIM into another device. If it is not detected there either, the SIM has failed and needs replacement. Call 0333 759 0000 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 → System → Reset options → Reset Wi-Fi, mobile & Bluetooth. This clears all network state and forces your OnePlus to re-detect the Sky Mobile SIM from scratch. Restart after resetting.

Frequently Asked Questions
Why does my OnePlus say No SIM with Sky Mobile?
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 Sky Mobile SIM in another device to determine if the SIM or the OnePlus is at fault.
How do I get a replacement Sky Mobile SIM?
Contact Sky Mobile on 0333 759 0000 or visit a Sky Mobile 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 → System → Reset options → Reset Wi-Fi, mobile & Bluetooth.
