Fortunately, there are several steps you can take to minimize these interruptions as well and protect your privacy.1) Dont answer calls or texts from unfamiliar numbersNot answering unfamiliar calls is one of the best ways to avoid a potential scam. Most phone carriers now label robocalls as "Spam Risk" or something similar. Scammers often use your local area code or even parts of your phone number to make you think the call is legitimate. That's why it's crucial to carefully check the number before picking up. If you dont recognize the number, its safest to ignore the call or text in case it's spam.2) Block the numberIf you get a spam call and want to prevent future calls from the same number, you can easily block it.

However, removing your number from these sites can help lower the chances of spammers getting a hold of it and reaching out to you. With a data removal service, your personal information is removed from the web so data brokers and scammers never get their hands on your personal phone number, home address or email address. While no service promises to remove all your data from the internet, having a removal service is great if you want to constantly monitor and automate the process of removing your information from hundreds of sites continuously over a longer period of time.Check out my top picks for data removal services here.
