   If yes or you don't know: Please contact Sprint Customer Care for help.

   If no: Please find the nearest Sprint Repair center and schedule an appointment so a Sprint technician can further diagnose the issue.

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

   You can connect to a Wi-Fi network as a temporary solution.

   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 Sonim XP5 S may decrease the signal strength.

   Connecting to a Wi-Fi network may also improve battery life.

Note: To optimize device performance, be sure your Sonim XP5 S is running the most recent device software. Check for software updates.

If you're still having issues, please contact Sprint Customer Care for more help.
