A. Review your billing statement carefully. Look for any charges that seem unfamiliar or are not clearly explained. Make a list of these charges and check the Verizon Wireless website for their billing policies and fee explanations. If you find discrepancies, document them and prepare to dispute them through the customer service channels.

B. Set up alerts for your account to monitor usage and charges. This can help you catch any unexpected fees early on. You can do this by logging into your Verizon account and navigating to the notifications settings.
