Why does the phone restart after changing the SD card shows that the SMS failed to be sent?

USB flash drive digital card mobile phone card:

First of all, you need to confirm whether the SD card is good, and you can try it by replacing it.

1.Connect the card reader to the computer and see if the drive letter capacity is good.

2.If it doesn't work, you can try another computer or card reader. If it still doesn't work, it may be that there is a problem with the card and it has nothing to do with the machine.

3.The machine changes to another good card, try to see if it still shows this problem. If it is still, it proves that there is no problem with the card, but the machine settings or somewhere are damaged, need to be repaired or whatever.

The card cannot be repaired, if there is data, it can be recovered. USB flash drive digital card mobile phone card: "prompt formatting", "unable to open normally","The device is not working properly"：

This situation is that there is no secure deletion during use, and after directly unplugging it, it will become "Prompt formatting" "Unable to open normally" "Device is not normal" "0 bytes" cannot be opened.

There are two types of situations.

1. Due to the sudden pull out of the U disk digital card mobile phone card, the loss of the FAT damage prompts insertion into the disk or formatting. In this case, it would be good to format the ** software on the Internet, such as diskgenius. If it doesn't work, try it with mass production tools.

2. Hard fault: due to sudden unplugging, the voltage instability may cause damage to the sperm element or burn the chip. Caused by the failure of the U disk itself such as crystal oscillator virtual welding.

In this case, I recommend that you find a professional data recovery company, or a USB flash drive repair company to try to repair the general recovery ** in about 200-300. Don't try to unpack the shell yourself, if there is a hard failure, you need to polish the memory card to extract the essence to recover, then 3000 up, don't try it yourself to avoid aggravating the failure. If you don't have important data, I'd suggest you switch it out!

If you have any questions, you can ask them, I hope to help everyone

Go to the SMS Settings Center and set up the SMS Center number.

It may be that the SD card is broken, try another one.

2. Operation steps: first back up the data, then copy the firmware package to the root directory of the mobile phone storage, shut down, press and hold the power button and the volume reduction key at the same time in the shutdown state to enter the engineering mode, clear the data and cache, manually select the installation file, and restart the phone.

3. Take out the SD card and wipe it before reinserting it, or replace the SD card to test whether it is the SD card. If it's not a problem with the SD card, you can go to the customer service center and ask the staff to help you check it.

System problems with it. Isn't it OK if you can use it?

The SD card slot is not in good contact, so go to the store and fix it.

Maybe it's a system reason, try to find another machine to read the SD card, if it can read the best.

If not, try to see if you can recover the data.

The landlord and I are in a similar situation! After my ME525 changed to an 8G memory card, the phone did not run smoothly without 2G, and the preview (hundreds)** folder could not be displayed completely for a long time, and it would crash in serious cases, and the battery should be removed and restarted. And it is very smooth to use the 2g Tsai Nai orange card!

Depressed! I also think it should be a card issue! I'm going to go to a ** merchant to change my card.

I bought it from Kingston. In addition, the landlord recently solved the problem of Mu Mountain, please tell the exact reason! Thank you!
