Some device models (e.g. iPhone 5) will not allow you to your device's latest operating system. In this case, you will not be able to install the 1VALET App.
You can find many second-hand phones for affordable prices. Check the system requirements for the 1VALET App on the App Store or Google Play to ensure you purchase a phone with a supported operating system.
If you have any questions or need further clarification, please do not hesitate to contact our Customer Support Team at support@1valet.com.
