How do you deactivate a chargeable SMS & MMS service to which you have subscribed?
The deactivation command is given in the general information on the service.
Keep this information in a safe place when you activate the service. Send the command to the short number given for the relevant service. Or, send the keyword STOP to the service provider's short number. This will stop all the subscriptions you have with the service provider. E.g: STOP to 60520. Failing this, contact call the service provider directly.
