With all the unsolicited phone calls people receive these days, call blocking is not uncommon. Home telephone services, as well as cellular services, provide call blocking as an option to your regular phone package. Depending on the service provider, the option may be included in your existing bundle, or may require an additional charge to activate. You still wonder if you have been blocked by someone, or if they are simply not answering your calls. In some cases, the result is the same.
Dial the number you suspect of blocking your calls. Look for signs of your number being blocked. These include a lengthy ringing without the ability to leave a message, or an extended ringing time, followed by a generic message that the subscriber you have contacted is not available.
Contact the service provider. Or search the website to learn about blocked call service. Service providers block calls differently. For instance, with Verizon's service, the caller will receive a message that there are calling restrictions on the line that have prevented the call from being completed.
Research Q&A forums on the web to discuss the topic of blocked calls with other individuals. Evaluate the signs and differences in services. Unless you hear an actual message saying so, it is not going to be clear that your phone number has been blocked. There are conflicting messages with no uniform signs from service providers. For instance, T-Mobile phones where the service is available, simply send the blocked caller to voicemail, which is a similar sign that a phone is turned off.
