Just got new BT sim. I want to lock my sim with a pin for security, like I did with vodafone. Is there a default pin I have to change? BT chat were useless as ever and suggested I use the PUK code!'

Hi @Cathiee
The SIM pin is turned off by default. But try 555
You can try 6666. If that doesn’t work you can find your PUK via your BT.com account select mobile and then the PUK is under sim
