So the question is still the same. I have blocked the number on my phone by going to the contacts and clicking 'Block this Caller'. I never get texts or calls or anything, but I do end up with a voicemail.YES it is blocked correctly. NO it is not a different number, I tested it with a friend.o the question is still the same.
