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.
To protect your SIM card from others using it for phone calls or cellular data, you can use a SIM PIN. Then, every time you restart your device or remove the SIM card, your SIM card will automatically lock and you'll see Locked SIM in the status bar.
