How to block spam sms

[passiflora]

Hi there, 

Since a while I receive spam sms from marvelous games ( phone number 4510086) 

In itself it didn't bother me too much because they went directly to my spam, but today when I wanted to pay my AIS bill, I realized that these text messages cost me 9 baht (x 30 days...)

Unlike true, I cannot find a ussd code to stop these text messages

I also can't find anything on the my AIS app to stop this scam

Any idea? 

Thanks for your help

Best thing to do is call AIS, they will block most of these spams and give a refund if you're getting charged. Also individually block the number by

go to phone

go to recent

long press the spam number

select block
