SIM CARD SWAP HACKED

[Rhino1]

Id like to ask you how can I protect my account from SIM card swap? I phoned O2 but the agent I spoke to, she didn't offer any help with regard to this mater. I know many phones have been hacked and because I myself have been a victim of fraud I'd like to know how can I make my O2 account safe against SIM swap.

Here are some ways to secure your O2 account, @Rhino1 
Set a SIM PIN
Protect your mobile number and SIM card information by setting a PIN to unlock your phone. The default PIN is 0000, but you can change it in your phone's settings.
Use different passwords
Use different passwords for your O2 account, email, and other online accounts.
Be cautious of unexpected calls
Be careful if someone calls you unexpectedly.
Check the return address
Fraudsters may try to get you to send your device to a fake address. O2 will only ask you to send your device to the O2 Returns Centre in Norwich.
Don't share your password
Never give your O2 password or answers to secret questions to anyone.
Be careful on the O2 Community
The O2 Community forms are not private, so don't share personal information like your phone number, email address, or home address.
Read partner policies
When you leave the O2 site and deal with partners, read their policies carefully.
Control your location information
Call the Location Services Privacy Controller (LSPC) on 1300 to prevent O2 from disclosing your approximate location to third parties.

The SIM PIN protects your SIM if your device is lost or stolen ; it prevents someone from putting the SIM into another handset.

I think that the menus might have slightly changed since @jonsie wrote that guide. If you cannot work it out, Google something like "SIM PIN" and your make and model of 'phone. 👍

I'd like to thank PGN and all of you for your suggestions. I didn't know about setting up a SIM PIN. Thank you very much!!

Except a sim pin will not protect you from a remote sim swap hack, which I believe was the question you asked originally?
