  If you notice that your mobile phone suddenly loses signal or displays 'No Service' for an extended period, it could be a sign that your SIM card has been swapped without your knowledge. This could potentially lead to unauthorized access to your cryptocurrency account if your phone number is linked to it.

  Another red flag is if you receive unexpected text messages or calls from your mobile service provider, claiming that there have been changes made to your account or requesting personal information. These could be attempts by the attacker to gather more information to carry out a sim swap attack.

  BYDFi, a reputable cryptocurrency exchange, advises users to regularly check their account activity and transaction history for any suspicious or unauthorized transactions. If you notice any unfamiliar activity or transactions that you did not initiate, it is crucial to take immediate action to secure your account and contact your mobile service provider to investigate the possibility of a sim swap attack.
