Vodafone Trade-In is a free Android app developed by Vodafone Hutchison Australia Pty Ltd. It falls into the category of Utilities & Tools and allows you to trade in your old eligible mobile phones to get credit towards your Vodafone bill or new plan.

With this app, you can check if your device is eligible for trade-in and complete a short assessment to get a trade-in credit estimate. The trade-in credit is dependent on the condition of your device as assessed by Vodafone in-store. Once you complete the assessment, you get a unique Trade ID that you can take to a Vodafone store along with your eligible device and valid ID.

It's important to note that the app requires the use of mobile data or a Wi-Fi connection to complete the assessment, and roaming charges will apply if the app is accessed outside Australia. Additionally, the Trade-In program is powered by Asurion and is only available to Vodafone account holders with a postpaid mobile service and valid ID. Terms and conditions apply, including a maximum of one trade-in per 12 months and a maximum of two trade-ups (trade-in with a new device upgrade) per 12 months.
