8. Troubleshooting

This section addresses common issues you might encounter with your TD-G19 radio.

A. About the Signal Issue

The free SIM card supports AT&T, Verizon, and T-Mobile in North America. The TIDRADIO PoC radio uses cellular networks for calls. Ensure you are in an area with good 4G signal coverage from these carriers to avoid issues.

B. About Network Fail

If you experience network failure, follow these steps:

  1. Modify APN: In the ODmaster APP, find "ME" → "APN". Turn on G19 Bluetooth and select "Headphone", then enter the APN code: globaldata. Reboot and test the radio again. (For G100, no need to turn on Bluetooth).
  2. Check the SIM card: If modifying the APN doesn't solve the problem, insert the SIM card into your phone, enable roaming, search for carriers, and test its internet access. This helps identify SIM-card problems.
  3. Persistent Issues: If the issue persists, please send us your SIM card number (ICCID#) and order number. We will conduct troubleshooting for you.

C. Frequent Disconnections or Choppy Sound

Usually results from weak signal. Try making calls in a well-signaled area.

D. Radio Not Registered

Usually, the radio cannot bind to the APP properly. If it shows as unbound, unbind and rebind. Restart the radio. Press PTT to enlarge the QR code for easier scanning if needed.
