there's a software (free and paid) that you can use to check if the number is still being used.
1. buy numbers from market - can go as low as USD0.10/number. even 3 cents also got
2. put the csv containing number list (as well as your other info - email, id, etc) into the software/script
3. the script then "ping" the number one by one. if got tone, number is still alive, and exits
4. put a note next to the number to say that number/you are still "alive"
5. gets the updated number list and resell for a higher price (can go as high as USD3/number)

put the number as scam also no use. they'll just get a new sim and repeat. the script needs to hang up quickly so they won't get charged. overseas ma. also have to be overseas no for legal and security reasons to protect the scammers. it's also why number registration does nothing but inconvenience legit people. u go kedai ahbeng and ask for numbers that no need to register, not expensive also.

the script is easily available if you know where to look.

and your number is not really a secret anymore. https://www.thestar.com.my/news/nation/2019...parliament-told
