MI 1S youth edition, with Unicom card, you can make phone calls, send and receive short messages, and you can't surf the Internet. The network is open. We have chosen 2G and 3G networks, but we still can't get online. Hello,

1. Please restart your mobile phone to see if it can be used.

Please put this mobile phone card in another mobile phone to see if it can be used.

3. If it doesn't work, please ask the mobile operator if it is a mobile phone card problem.

4. If it still can't be solved, please back up the data, enter the recovery to clear the cache, user data and all data, and brush the latest development system. Do not restore the system settings after entering the system.

I hope the above reply is helpful to you.

Thank you for your support and wish you a happy life!
