Identified
We have identified an issue affecting some Sonim XP5+ LTE Radios where the device may lose its configured APN, resulting in a dropped cellular network connection. Getting you back online is our top priority, so please follow these quick steps to restore your service:
1. Close Tango Tango: Completely close the Tango Tango app on your radio. 2. Locate Your IMEI: Find your device's IMEI number and note the last four digits. 3. Connect to Wi-Fi: Ensure your device is connected to a stable Wi-Fi network so we can communicate with it. 4. Request a Remote Update: Text the last four digits of your IMEI to 888-826-4607. Our team will use this to remotely push a network update directly to your device. 5. Restart the Radio: Once our team replies to confirm the update has been pushed, simply restart your device.
Your cellular connection should automatically restore once the device powers back on. If you continue to experience any connectivity interruptions after rebooting, please reach out to our support team for immediate, hands-on assistance.
