spam calls

Spam calls or messages or even spam emails are some of the things we all hate and wish we never have to handle them or even receive them in the first place. While blocking spam emails is relatively easy and could be avoided by simply keeping our email ids confidential, it is not as easy to avoid spam calls or text messages.

Because you might get spam or an advertising call from anyone ranging from telemarketers, unknown callers, scammers or even from your carrier calling at you at a wrong time or a place. Unfortunately, like email service providers, most Android phones do not come with a built-in option to prevent or block these spam calls or messages.

Thankfully, you can make use of the multiple third-party apps available to download for free from the Google Play Store, which allows you to block all known spam calls and messages, identify unknown calls and messages and even filter the numbers you want. So, here is a list of 9 most popular Android apps to block and prevent spam calls and messages for you to choose from.

Truecaller: Caller ID, spam blocking & call record

If you are someone who receives a lot of calls from unknown numbers on a daily basis regarding your work, then you might have a hard time trying to figure out whether the call you are getting from an unknown is a genuine call you are expecting or just Tranother scammer trying to annoy you and waste your time.

Truecaller is a free app for Android that can help you with this situation. The app automatically identifies the number and will display the name of the contact so you can be sure to know who is calling from the unknown number before picking up the call.
