1.Shut down and restart.
2.It is also possible that the Internet connection parameters have been changed, if you forget how to change back to the previous parameters, call**Ask you**card attendant (Unicom, Telecom, Mobile) He will prompt you how to modify.
3.This method is the most effective, no matter what problems occur with your software, factory reset can be solved, the so-called factory reset is the soft grid, delete all the information files in your phone memory (excluding memory card), and make a good backup of information and books before the soft grid.

It is estimated that the landlord is a parallel import.
However, now both the European version and the Hong Kong version can be exported in Chinese Simplified. The easiest way is to read the manual and see how to change the input method. Is this phone full keyboard?
Look at the landlord doesn't look like a master with a mobile phone, it's best not to blindly brush the machine yourself, to brush the machine and read tutorials and articles on the Internet.

If you turn off the phone for ten minutes, it is estimated that there will be no problem.

The system is running out of memory. Here are a few suggestions for you: First, delete historical text messages.
Second, remove system junk. Third, uninstall the software you don't need (the software is installed too much, and I really don't want to delete it if I exceed the memory load of the phone, so I have to change the phone with a large memory). After the above process, I believe that in a few seconds your text message will come.
