Change Primary Number - dual SIM

Hi kirstenn1,

If you are on a text message and want to change the default SIM card you need to:

1. Open Messages and the conversation with the contact
2. Tap on the Contact (at the top) and click on info
3. Click on info again
4. Under the contact name, you should see "last used: Primary >". Click on this option and then choose the Primary or Secondary SIM

You can also change the Default Voice Line altogether from Settings > Mobile Data > Default Voice Line.

Let me know if this helps, otherwise, can you please elaborate further on your question?

Hi kirstenn1,

I understand you have some questions about using the Dual SIM feature and the usage when selecting text messages for different lines of service. I recommend checking this article: Using Dual SIM with an eSIM
