A: When the green indicator keeps flashing, it means that the box cannot register to 3G network.
You can check from the following aspects:
a. Whether the plugged box is covered by any metal. If yes, remove the metal, and ensure that the box is not interfered by any electricity device.
b. Whether the SIM card is not inserted. If not inserted, Insert based on the instructions on the cover. If inserted, check whether the SIM card is inserted properly. If not inserted properly, insert the SIM card properly.
c. Whether the network data in SIM card is insufficient. If insufficient, please recharge.
d. Whether you are outside the network signal coverage.
If all preceding conditions are not true and the green indicator still flashes, replug the box. Contact after-sale personnel if there is still no response.
