How to report fraudulent SMS to the operator
Fraudulent SMS has been around for a long time in Indonesia and there may be people who get them once a week or once a month. Of course it irritated the scammers who wanted to be called, but there was no reaction. There is no other option but to report the number operator.
It’s a good thing to report bad behavior if you or your friends ever receive an inappropriate text message, like getting a car when you didn’t attend the event, or something else like a loan application.
This scam is used to use newly activated starter cards and the scammer encrypts the numbers and sends them one by one via SMS.
Sometimes people who are gullible are people who have never received a fraudulent text message. If that person has a cell phone, a fraudulent text message comes along and it is dangerous to believe.
With some operators, the block number method is only available via SMS or direct call Customer service no problem either. The following is the SMS format from several operators in Indonesia.
Telecomsel
SMS formats: Scam # spoof number # fill out a scam SMS and send it to 1166xL.
SMS formats: Report the # fraudulent number # of the case you are complaining about and submit it to 588INDOSAT
SMS formats: SMS (space) The fraudulent number (space) Fill in the fraudulent SMS and send it to 726
There are still 3 operators who know the SMS format to report fraud. In order for you to block the reported number immediately and not make any mistakes in the content of the SMS, a check may be carried out before any action is taken.
Don’t worry about card users other than the above. You can inquire through customer service or by email. Please click to go to the respective provider’s website: Three (3) Axis Flexi Smartfren Esia.
If anyone finds fraudulent SMS format other than the three above, please comment. And if it’s true, I’ll update this post soon. 
Hopefully useful and good luck
