There are two areas where you define the language for your ServiceNow mobile apps: the instance language setup and the mobile app language setup.

Note: For the optimum user experience, the same language should be used for the instance and the ServiceNow mobile app language.

Defining the ServiceNow instance language

You can change the instance language by selecting the relevant language from the drop-down field in the mobile app login screen. If this field isn't displayed, this means that your instance has been preconfigured for a specific language and can't be changed.

The Preferred Language is the ServiceNow mobile app language and can be configured from this page. To change the language, see Defining the mobile app language.

The Instance Language is display-only and cannot be configured on this page. To change the instance language, see the following section in this topic, Defining the ServiceNow instance language.
