For sure I agree with you Star Tech it gets me also how they always want my cell number or email and I am like you I don't want or need the junk stuff and right now Big Snip !
I have my old I phone 4 which still works so I bought a sim only plan for $ 10/ month to get a valid mobile phone number
I then got a G-mail account to go with the phone
Once activated I pull the sim from the phone and it only ever goes back in when I need that number for things like 2 factor authentication and of course I never ever go to G-mail to retrieve the e-mails that I did not want to get in the first place
Funny enough the last time I activated the phone the message box was full and there was over 1000 missed calls
So everything gets deleted then I log into what ever I needed the authorization for then pull the sim again
I deregistered for GST ( Goods & services Tax ) when the government ended paper lodgement & required them to be done either on a phone or tablet ( not even a computer ) that is less than 3 years old .
I am about to change my business from a PTY LTD to a Sole Trader because the government was embarassed by an investigation that showed they had not done their job properly and there was over 1/2 million fake companies out there with directors who were dead or were homeless people who got a free bottle of scotch if they signed "this" form .
So now we need yet another number ( directors Identity number ) but to get one the only way is to use a smart device to get a number from the "one stop government shop" to get an app for you phone ( that is less than 2 models old ) to complete the registration process & be given a tag that remains in your phone which links your directors number to your tax number to your Medicare number to your bank account number and store it all on a "smart phone".
Any one see a problem with that ?
