How do I set Mint as my default line for iOS?

If you have dual SIMs, you can select one to be a default line for calls and data. It also doesn’t have to be the same line. You can specify a default for each one.

To set Mint as the default calling line on iOS:

1. From your phone’s Home screen, select Settings
2. Scroll down and select Cellular 
3. Tap Default Voice Line and select your Mint phone number (It’s selected when a checkmark is present)

To set Mint as the default data line on iOS:

1. From your phone’s Home screen, select Settings
2. Scroll down and select Cellular 
3. Click on Cellular Data
4. Select your Mint phone number as the default line (It’s selected when a checkmark is present)

Cellular data switching

Turning the feature “Allow cellular data switching” on will allow your phone to use cellular data from both lines, depending on coverage and availability.
