Unfortunately, you can't. I have had problems with that, too. The only thing you can do is just not answer. I also say on my voicemail that I do not answer restricted, unknown or unavailable calls. I tell people to leave a message. That way I know who is calling.How can I block calls from unavailable numbers?
No you cant block unavailable numbers. But what you could do is the next time the blocked number calls record the date and time that they called and then call tmobile and then tell them if they could track down the # of the blocked # and tell them the date and time when it happened and tmobile will be able to see what number called you. good luck
