Apple iPhone: How to enable the Multi-Network Add-On
Enabling the Multi-Network Add-On
Login to your US Mobile app. Download it for iOS here.

Scroll down and click on Multi-Network Available under Add-ons.
Review the Add-on details and click Continue.
Review payment details and Checkout.
Click Start Activation.
Select your preferred network for the additional line.
Click Activate.
All done! Time to install the eSIM on your device.
Installing the eSIM
If you're running the latest version of iOS, you'll get a notification on your iPhone to install the eSIM. Alternatively, you can tap on the Install eSIM now button on the app to get set up.
If you have another phone or computer, you can pull up the QR code on it and then scan it with your phone to install the eSIM. Go to Settings > Cellular Service/Mobile Service > Add Cellular Plan/Add eSIM > Use QR code.
Once the setup completes, your Multi-Network line will be good to go!
Switching between your Primary line and Multi-Network Add-On line
Once you've got the lines installed in your iPhone, both of them will work at the same time for calls and texts. However, your iPhone can only connect to data using one network at a time. If you move to a place where you're not getting the best data speeds, here's how you can easily switch your default data line:
On your iPhone, go to Settings.
Tap on Mobile Service/Cellular Service.
Tap on Mobile Data.
Select the line you want to switch to.
You can also turn on the toggle for Allow Mobile Data Switching. Your phone will automatically switch to the other network once it detects that you're in a low coverage area for your primary network
