How to block Calls and SMS from Numbers on Infinix Phones

It’s safe to say that older infinix phones up to the HOT 3, runs infinix XUI. While newly launched infinix phones like the Hot 4, NOTE 3 and HOT S, runs XUI which is the brand’s refined User Interface.

Thankfully, same process can be done on both UIs.

  • Simply Tap on the App drawer and locate XManager app
  • Launch the XManager app and tap on Harassment Block
  • Under the Harassment Block menu, tap on the blacklist tab and choose the option to add blacklist.

You can thereafter, choose to add numbers from your call log, contacts, SMS or manually input the numbers.

It’s that easy!

If you want to customize the blacklist a bit, you can tap on the gear icon (settings), and choose if to block both SMS and phone calls or just calls from the blocked contacts.

So, there you have it. Blocking contacts on infinix phones is that easy. Got questions? Please free to share using the comment session.
