I can’t seem to send text messages using my secondary sim card. I tried choosing a friend that I had never texted before and it let me choose which sim card to text, however, if I choose a friend that I have sent messages to before using the primary sim, there isn’t a button for me to choose my secondary sim. How should I solve this problem?
iPhone 11, iOS 14

If you haven't called that contact, your iPhone uses your default number. If you want to, you can specify which number to use for your calls with a contact. Follow these steps:
