What if Xiaomi's mobile phone can't surf the Internet and send messages?

Unable to access the Internet. General treatment:

1. Check whether a single program or all programs can't connect to the Internet.

2. Check whether the cell phone signal is good (i9000 should confirm whether roaming is enabled).

3. Check whether a firewall or some software is used to restrict the networking of some programs.

4. Set the access point with one key of Haizhuo.

Put your card on another mobile phone and see if you can connect to the Internet.
