I scanned the QR code on the back of Unicom Smart Wojia Cat, and suddenly the network was disconnected. I can't log in, nor can I log in to the mobile phone business hall, and there is no text message. If there is a problem that you can't connect to broadband, you can do the following:

1. Call a phone. If a router is used, please temporarily disconnect the router test;

2. Check whether the network cable or telephone line is loose;

3. Check whether the network equipment such as modem is overheated, restart and try again;

It is recommended that you scan your computer for viruses.

The above situation has not been solved. You can feedback relevant information in the mobile phone business hall-customer service-broadband troubleshooting, and our company will get in touch with you as soon as possible.
