# Study-provisioned Smart Phone Set Up (iOS)

## Instructions for configuring study-provisioned iOS smartphones for participants without personal mobile devices.

During the onboarding session, confirm whether the participant’s personal smartphone meets the technical requirements for the Hexoskin OneApp (see the [smartphone provisioning decision tree article](https://site.hexoskin.com/smartphone-provisioning-decision-tree?hsLang=en)). If it does not, provide a Study Smartphone from the inventory available at your site.

Please ensure that the data roaming is enabled on the study-provisioned smartphones. 

To do so, go to the iPhone's Settings > Cellular > Cellular Data Options > enable "Data Roaming".

If the Hexoskin OneApp is not yet installed, it will be automatically installed once "Data Roaming" is enabled, so the participant can begin collecting data.
