Are you suspicious that your cell phone is being blocked by someone? With today's technology, most cell phone service providers allow customers to block 10 to 15 numbers so that they won't receive incoming calls from certain people.

Find out which service provider the person is using. Verizon and AT&T are common service providers. Each service provider uses a different prerecorded message to play to blocked callers; you can use to determine if you are being blocked. If you do not have access to this information, continue the steps anyway.

Dial the phone number of the person you think may be blocking you. If you get through to him/her or get voicemail, you are not being blocked. However, if you receive a recorded message, then it is possible you are being blocked.

Write down the recorded message you hear. You will use this to compare it to the various recorded messages from each service provider.

Compare the message that you wrote down with these standard prerecorded messages from popular service providers. If your cell phone number has been blocked by an AT&T customer, you will hear a message that says: "The AT&T subscriber you are trying to reach is not available at this time." If your cell phone number has been blocked by Verizon, Qwest or Century Link, you will hear a message stating that the customer is not currently accepting calls. If another service provider is being used, go to that company's website and contact customer service to determine what message is played to blocked callers.
