Received an unknown SMS English code.

Didn't you see the number that sent the text message?

If the SMS number is a normal number, send it, such as a picture, FLASH and so on. The mobile phone can't display, so it is displayed as garbled code. If your mobile phone is multifunctional, it is a problem for the communication company.

If it is an abnormal number, just delete it directly. It may be an advertisement, a virus or something. Just ignore it.
