  If you notice that your phone suddenly loses signal or displays 'No Service' for an extended period of time, it could be a sign that your SIM card has been swapped. This could potentially lead to unauthorized access to your cryptocurrency account if not addressed promptly. It's important to contact your mobile service provider immediately to investigate the issue and secure your account.

  Another sign of a sim swap attack on your cryptocurrency account is if you receive unexpected text messages or emails from your mobile service provider regarding changes to your account or SIM card. These messages may include instructions to confirm or authorize the changes. If you didn't initiate any such changes, it's crucial to treat them as suspicious and take immediate action to protect your account.
