Apple's mobile phone has not been displayed China Mobile is always English letters, it is a NAND hard disk error, most of them are flash memory or peripheral circuit faults, which are motherboard circuit faults. Causes:
1. The mobile phone should be cut off in time after the water enters the water and the circuit should be fully cleaned, and the water should be dried before turning on the phone. Due to the design of Apple's hands, it is more difficult for individual users to remove the battery, resulting in untimely cleaning, and some users can be used normally during the short rental period after entering the water, and they are not cleaned up in time and continue to use, resulting in serious failures.
2. Sudden restart of display NAND in normal use: This kind of fault is generally difficult to repair, and most of them are caused by damage to flash memory circuit components.
3. Flash memory chip itself is damaged: this kind of situation is relatively rare.
Repair method: The cause of the failure is different, and the repair method is also different, but this is not to be solved by repairing it yourself, it is recommended to go to the after-sales repair, because some serious failures can only be solved by replacing NAND.

Telecom's Apple mobile phone displays the four words of China Telecom, which should be checked from four aspects: SIM card, card slot, local signal and card sticker.
The main reasons and solutions for not showing the four words of China Telecom:
1.Check if the phone has a SIM card inserted, a SIM card is required to connect to the signal.
2.Check whether the SIM card slot or SIM card is damaged. You can insert other SIM cards to try, and if there is no problem with other SIM cards to display, you can rule out the problem with the card slot.
Then put the SIM card of the mobile phone itself into the card slot of other mobile phones to see if the signal will appear "China Telecom" four words, if the display is normal on other mobile phones, you can rule out the problem of SIM card. If the card slot is damaged, it is recommended to replace the card slot, if the SIM card is damaged, please go to the business office to replace the SIM card.
3.When the signal in the place is not good and the signal cannot be searched, there will also be a phenomenon that "China Telecom" is not displayed, and you can change to a place with a good signal to search.
