The service provided by the network operator to phone users such as waiting music, ringtones, missed call notifications, games, watching video clips, etc. data limit… bring a lot of benefits when used.
Some carrier services may cause you to be charged monthly
However, this is also the reason why users are charged monthly if they accidentally register without knowing it. This is similar to the case of a registered user but forgot to send a cancellation message, causing the service to continue to be maintained even though it is no longer needed.
In case you have signed up for many different services but forgot about it for a long time, or accidentally registered but didn’t know it yourself. Here’s how you can test the services subscriber using.
How to check the services in use of Viettel, MobiFone and Vinaphone carriers
To look up subscriber services in use (for 3 operators Viettel, MobiFone and Vinaphone), follow the following texting syntax:
If you have a situation where your money is deducted for no reason, try to check this way
– For MobiFone network subscribers: text KT to 994;
– For Viettel network subscribers: text TC to 1228;
– For VinaPhone network subscribers: text account to 123.
After you perform the lookup, the operator will provide information about the services being registered on your phone number via text message. Accompanying that is the fee and the syntax to cancel these services. If you discover a service that you do not feel is necessary to use, unsubscribe according to the provided syntax.
In addition to services from carriers, readers are also wary when downloading applications from 3rd parties, as well as applications that require a lot of important access rights. These malicious applications can voluntarily register for paid services or cheat ads, at the expense of users.
