I would recommend an app called LEO Privacy. It can help you add the disgusting phone numbers to blacklist to stop spam and harrassing phone calls from bad guys. LEO Privacy Applock Boost Hide Android Apps on Google Play

go to your phone icon, click on that and then recent and then find the number and press on it and hold, a menu comes up that says add to reject list.

yes, in phone number recall area. number history. find number you want to block hit settings then add to reject list.

In iOS 7, there is an update that allows you to 'Block the Caller' this should block Text Messages and Calls from that number. If that does not work, you can reach out to Law Enforcement about the harassment, or your Cell Phone carrier to block that number all together... Best of luck with that.

Bev,
Certain phones do have an option to filter incoming calls and msgs. Your may have one too. Just check the settings under Security. If not then you can download a software "BLOCKER". If you can install it on your device then you would be able to block unwanted calls and msgs. Search google for blocker to be taken to the site for download free.

Nokia 1100 does not have the option to block an incoming call. If it has internet, then download BLOCKER and install it. You would be able to block not only select incoming calls but unwanted messages as well. If there is no internet facility available on it then you will have to just ignore those unwanted calls.

How to block a call for A PARTICULAR NUMBER IN C2-01

Hi
If you have a Samsung phone, you have the ability to send an incoming call directly to voicemail, without it even ringing on your device.
Look for the "block list" feature on your device.
Or calling customer care for help in blocking a specific phone number is one of the most suggested solutions. Alas! it doesn't work most of the times. But some carriers do let you block a phone number but only after verifying the facts and asking few security questions.

Hi, on the phone you have it is not possible to block any number from calling, it just doesnt have the memory to have that kind of software, the only other option you may have is to call your service provider and ask them if they can direct a call from a certain number direct to your voicemail or see if they can block the number from their end.

on newer phones it is possible to block any number you like but on your phone its just not possible.

sorry i couldnt be of more help, but the phone is no capable of doing what you want, a newer phone would, but try calling your service provider and tell them you keep getting nuisance calls off a certain number and then see if they will block the call from their end
