Which app is primarily focused on device manuals and coupons?

The Team Wireless App is specifically designed to provide users with device manuals and access to coupons. It serves as a resource for customers looking to gather information on their devices, helping them understand how to use various features effectively. Additionally, the coupon feature enhances its utility by offering savings which can be appealing for users looking to maximize value.

In contrast, the other apps focus on different core functionalities. My Verizon primarily offers account management capabilities, allowing users to view their usage, bill, and account settings. Tech Coach is concentrated on providing customer support through technical assistance, focusing on troubleshooting and device optimization. Verizon FiOS is related to the company's internet and television services, focusing on content consumption rather than device management. This distinction highlights the unique purpose of the Team Wireless App in relation to the other options.
