Messaging app-to-app is the most cost effective messaging option. When in cellular or Wi-Fi coverage, you may send messages to other ZOLEO app users or ZOLEO device users. The app determines the lowest cost method for routing messages. For this reason, we encourage your contacts to use the ZOLEO app even if they don't own a ZOLEO device.
Here are the steps for inviting a friend to use the ZOLEO app:
1. Open the ZOLEO app.
2. Tap on Settings.
3. Tap on Invite a Friend.
4. Select their preferred contact method.
5. An introduction to the ZOLEO app along with a download link will be sent.
