USSD is handled via a web activity to the Dialer so it is not responsibility of Cost Control to properly cancel the USSD session. Germán, what do you think?

Is this a new regression or a partner requirement?

I think it is a new regression, but I´m not 100% sure.

I am sure Fernando will be able to tell us something about it ;-) Thanks!

Removing component Cost Control as the Cost Control application does not handle USSD. It only invokes the dialer via web activity.

Changing component to Dialer. If the problem is unrelated, please, change the component.

I finally managed to check this with Carlos and I am pretty sure that this is the expected behavior.

What is happening here is that Vivo, after cancelling the USSD session, sends an unsolicited USSD message reminding the user that she can always use that USSD code again to request a refill. The translation of the received USSD is something like: "Whenever you want to do a refill, call for free * 321 # and recharge". IMO politeness is not an issue :) and this is a RESOLVED INVALID.
