This is USSD notification from your network. You can try this, but can't guarantee that it will work 100%. No harm trying though. Send SMS to 123 as PCNINFO NO.

PCN refer to Post Call Notifications.

Also there are some ussd notification blocker apps available in play store. You can try them at your own risk.
