I've been using my real phone number for my online shopping such as eBay and I've been getting alot of spam calls. I think someone is farming mobile numbers from postal delivery labels as they usually print my number on there.
Anyone can recommend any services such as Google VOIP numbers that I can use in Australia, so that I can regularly change the phone number. I want it to be active, so that they can contact me in the case of an emergency, but I don't think I will keep the number for long term.
What if you change your number and someone tries to call the old number in the case of an emergency?
