It seems like they are becoming more frequent, I haven't given my cell number to any random companies that I'm aware of. Usually just a some spam on a tape recording. It's especially annoying when I'm sleeping.
there is a do-not-call registry for cell phones now, if you're in the US. I believe they have something similar in Canada as well, if that's where you reside.
I've had the same mobile number for 9 years now and I don't get any spam calls. There was a time in 2002 where I did but it's been clear sailing ever since.
I once had a message from a local (Hawaii) guy talking thick pidgin (If you dont know what that is, look it up on YouTube) yelling "YOU KICK MAH DOG!!! I KILL YOU, I KILL YOU!!!!!!!!!!!1!!11!!" for about 5 min. It was quite scary, as I was only in 6th grade. The funny thing is that I never kicked a dog......
While adding your cellphone to the National Do Not Call Registry may add some additional protection, FCC regulations already forbid most telemarketing calls to cell phones.
i get the same stupid timeshare call, im not even qualified to BUY a timeshare...what really bugs me is calls to my pay as you go phone i just dont answer it if its not someone i know
