This article provides troubleshooting tips for the HTC EVO 3D. It contains troubleshooting steps and advice to help resolve data connectivity issues.

• Unable to connect to the internet
• Unable to browse websites
• Unable to send multimedia messages (MMS)
• Internet-dependent applications open but do not load content
• Unable to send or receive email

The following steps and advice can be used to help identify the underlying cause of the issue and resolve it. After completing each step, test to see if the problem still occurs. If so, proceed to the following step.

1. Verify your HTC EVO 3D is connected to the Sprint voice and data network using Sprint Zone.

   Your HTC EVO 4G mobile data connection can be manually enabled or disabled. If mobile data is disabled, features and processes that require a data connection will not work. Follow these instructions to access Sprint Zone and browse to Help > I Need Help. This will automatically check the voice and data connections. If either connection fails, tap Update Profile to update the data profile. This can potentially fix connectivity issues. If updating the data profile does not resolve the issue, move on to the next step.

2. Perform a soft reset.

   This process will re-establish your HTC EVO 3D connection to the Sprint network. To perform a soft reset, turn your HTC EVO 3D off and remove the battery. After 30 seconds, reinsert the battery and turn your HTC EVO 3D back on. If a soft reset did not solve the problem, then move on to the troubleshooting steps below.

3. Are other Sprint customers experiencing the same problem, in the same location(s)?

   If yes, or you do not know, please contact Sprint Customer Care for assistance. If no, please visit the nearest Sprint Service and Repair Center to have your phone checked by a Sprint Technician.

4. Temporary solution: Connect to a Wi-Fi network.

   If a mobile data connection cannot be established, connecting to a Wi-Fi network can serve as a temporary solution. When connected to a Wi-Fi network, your HTC EVO 3D web browser and other internet-dependent applications will work properly. Connecting to a Wi-Fi network may also improve battery life. To connect to a Wi-Fi network, follow these instructions.

   Note: Most Wi-Fi networks have a range of less than 100 feet indoors and up to 300 feet outdoors. Objects between the router and your HTC EVO 3D will decrease the signal strength.

Note: To optimize device performance, ensure your HTC EVO 3D is running the most recent device software. To check for software updates, follow these instructions.

If you are still having issues, please contact Sprint Customer Care for further troubleshooting.
