Do you dare to send text messages when you have a virus in your mobile phone?

If your friend's mobile phone is also a smart phone, it may still be contagious, and the virus still has an impact on the SIM card. I suggest you turn off your cell phone:

The first step is to back up all the useful things in your mobile phone, such as phone book, photos, etc.

Step 2, take out the mobile phone memory card.

Step 3, enter *2767*3855# (this is the grid code) on the mobile phone.

Step 4, format the mobile phone memory card on the computer with a card reader.

Step 5, insert the memory card back into the mobile phone.

This way, the virus is formatted, and you can safely send text messages to your friends.
