We are all subscribers of one or the other SIM.
Whether we understand it or not, we launch various services on our mobile connection / SIM. As a result, the services deduct a certain amount of money from the SIM's balance.
It can happen at different time intervals. There is no limit to the suffering of SIM users with these. These deductible services are called value added services, or VAS for short.
However, the hope is that it is possible to turn off these value-added services.
Hope you can use this app to solve the problem of balancing your mobile, thank you.
