If the network signal of the watch is not good, it is recommended to try and confirm as follows:
1. Make sure to use standard Nano-SIM card, and eliminate the use of "cut card";
2. Make sure the signal in the environment is normal, you can change the environment and try again;
3.Ensure that the SIM card data traffic Internet function is normal;
4. Change the SIM card of another operator and try again;
5. Ensure that the SIM card has normal insertion.
