1: Keep a Record Maintaining a call log can be beneficial in recognizing patterns of spam calls. If a specific number, like 91743000, repeatedly appears in the log, it’s likely a spammer. 2: Avoid Answering Suspicious Call If you receive a call from an unfamiliar number, especially one that seems suspicious, it’s best not to answer. Let it go to voicemail, and if it’s essential, the caller will leave a message. 3: Utilize Caller ID App Caller ID apps can help identify potential spam numbers, including the 91743000 number. These apps access extensive databases to provide information about incoming calls. 4: Block Unwanted Number Smartphones have the option to block specific numbers. If you’ve determined that 91743000 or any other number is spam, block it to prevent future calls.
