Heh heh. I'm not having this problem but I can confirm that Garrett is. Why is it such a big deal? It's just a random number. Does it really inconvenience you?

I received 25 calls from this number between midnight and until a couple of minutes ago. Surely somebody must be able to do something! I tried to switch on internet call barring. Will see if that helps. From my research it appears that 087 is VOIP numbers apparently sponsored by Vox Telecoms in RSA. Maybe VOX should answer to this, else I might swearing or claim from them in Latin for nuisance!

Same thing. I get phoned 4-5 times a day. It's definitely automated. Started 2-3 days ago.

Same sh!t, & same number... Mn started about 2days ago, hope stops soon tho. Not too clued up on phone, bt if won't do anything to my software, rite???

i have the same problem...same number...same problem...

I have exactly the same problem with the same number.  When I pick up my phone says "number not allowed" and if I call back it says "number incorrect".  Wonder if its not phone spam and MTN blocks it.
