meaning: it's stopped. The mobile phone has been stopped for more than 2 months to recharge, and it has become an empty number, so it will show that you can't access the mobile network whenever you dial any number.

It may be that there is something wrong with the mobile phone. Solution: First, find the settings on the mobile phone, and click the settings above the phone plane. Click the small sign of the mobile phone card first, and then click the network operator. Then click the symbol, and then click search network. Wait patiently.

a network matching your mobile phone appears, as shown below. If the mobile network of your mobile phone card does not match the network displayed by your mobile phone, it proves that your phone card does not match your mobile phone. Therefore, after the mobile phone is plugged into the mobile phone card, an x sign appears in the place where the signal is displayed, and the call will also show that the mobile network cannot be accessed.

restart the network: sometimes the APP may not detect the signal of our mobile phone, so the first step is to turn the mobile phone into airplane mode, restart it, check whether WLAN and 4G are turned on, and open the software to try again.
