I have damaged my sim card from switching sim cards in my phone too many times. My phone does not read my sim card anymore (defective sim card, contact provider message). I really need to get it changed ASAP, but I would also need to keep my phone number. Unfortunately, I am abroad and can't simply go in an O2 shop to get help.
SIM card PIN. You can set up a PIN for your device SIM card, which you can use to help prevent unauthorized use of your SIM card in another device. For example, if you lose your SIM card and someone tries to use it in another device, the SIM card can't be used unless the PIN is entered correctly.
