however, even changing to a new number won't cut out calls forever. i knew someone that worked for a cold calling company, they went by numbered lists and usually have no idea who they are phoning. if registered with tps companies can get fined if they call you, but overseas calls aren't part of this and would continue to call. to emphasise this, i had a payg. no one knew the number and i never made a call or text. it was just used to update twitter for business. i got lots of cold calls on that.
ive had someone asking for richard for two years who wants to move to australia and they want to help. blocked the numbers many times but new numbers keep popping up. .
