Mobile number location tracker and Call Blocker is an app that allows you to keep track of your phone number, so you can keep track of where your phone is, even if you don’t have a signal.

You can also choose to block calls from people you don’t want to talk to, which is a great way to keep your phone free from spam and anonymous calls.

Once you have downloaded the app, you can see all the options that you have available. You can add your number to the blacklist or whitelist, and you can also choose to block or allow calls.
