Sorry, there was a problem. Please try again later.I personally have not used the block function on this phone. If it has a limit of 250 numbers, that will be it. Electronics has limitations as far as space and that is what was allotted for that function. I have cable phone service, which is the next best thing to an old fashioned telephone line. The provider also blocks numbers if I ask them to. That is one of their features. As to what limitation they allow, I don't know. But if you haven't already, I would recommend to you to add your number to the National No-Call list. If you keep getting annoying calls from a certain number, you easily report it on that web site. I was getting a call a lot and reported it. The next day, no more calls from that number. I hope that this helps.
