How to open the flow? I sent a message to10086+10655133 after GPRS 5, saying: the access code you entered is wrong!

Android dual card dual standby mobile phone, I mainly use mobile card (phone+Internet), Unicom card is sent by broadband (two cards are sent together, no monthly rent, two cartoon characters are free). By default, the mobile card is installed in slot 2 (GSM) and Unicom is installed in slot 1 (GSM+USIM), so 10655 133 always prevails. Moreover, there are errors in automatic flow calibration like 360. Later, I realized that this machine uses the default card 1 to send text messages. However, the general short message code 10086 can only be identified and sent to Unicom by mistake, so the above situation has occurred (this number was once set as a junk short message number to block, but it could not prevent receiving any short messages with wrong codes from this number). The later solution was to change the position of the two cards. Mobile card loading slot 1 and Unicom card loading slot 2. It's been two weeks now, and I haven't received the text message at this number.
