Haier u56t SMS Problem

Ask the mobile sales department to change it for you, and they will change it for you. Or you try to reissue your mobile phone card, or your SIM card may not support this mobile phone (in some cases). You can try another mobile phone of the same model. If you can get in, it means it's the card. If you can't get in, it means you need to get a new card! This is a simple method. Why are mobile salespeople so stupid? And if you encounter this kind of thing, call 10086 to handle it and complain to them. Mobile attaches great importance to complaints and will help you deal with the problem in the first time!
