When making a call, you can easily choose which number to use. Open your phone’s dialer and select the line you want for your outgoing call. You can also view your recent call history to see which number made or received each call. ![image iphone dual sim select dial-2](https://help.redpocket.com/hs-fs/hubfs/Knowledgebase%20Images/image%20iphone%20dual%20sim%20select%20dial-2.png?width=235&name=image%20iphone%20dual%20sim%20select%20dial-2.png)   ##### **Do my internet settings affect calling and texting?** Yes! Most devices let you use data from one or multiple lines. You can turn on **Cellular Data Switching**, which allows your phone to automatically switch between lines for internet access. Or, if you prefer, you can set your device to use **only a single line** for data. If you choose to use just one line for internet access—like your primary line—your other lines won’t have data access. Don’t worry, though: those lines will still be available for calls and texts. **Important:** Even if you only plan to use one line for data, it’s still essential to **enable LTE** on all of your lines, including secondary lines.   ##### **To enable LTE:** 1. Power on your device and open **Settings**. 2. Select your additional line(s). 3. Choose **Enable 5G**, **Enable LTE**, or **Enable VoLTE**. **Note:** If you don’t see **Enable LTE** right away, first tap **Voice & Data**.
