How can I delete the message " Number changed to Primary " on my iPhone ?

We have a two prepaid phone cards since Christmas. I have an iPhone and my husband has a simple flip-phone. The first SIM card did not work and the second SIM card looked his simple flip-phone . That's way, we exchanged the SIM cards and we inserted this second SIM card into my iPhone. I could not access Voicemail and send messages, just receive messages. I called Bell Customer Service from my iPhone and the automated service was unable to determine the input numbers from my keyboard.Then my iPhone went grey and there was the message: "Error performing request Unknown Error ". I called Apple Support. After that, I received an Apple survey and the message: " Number changed to Primary ". Yesterday I returned to the Bell store and they put a new (third) SIM card into my iPhone for free. Now I have connected the message: "Number changed to Primary" with every message. How can I delete this message ?

iPhone XS, 12

Once you activate a second SIM or eSIM, you must label your plans and choose which one is your primary. iMessage and FaceTime use your default line to call and send messages.
