Who knows the user name format of Zhejiang Jinhua Mobile Broadband?

The old JKD123456 format of JKD+ numbers.

Occasionally, some of them are telephone numbers (I did it a long time ago, and the number may be 7 digits instead of 8 digits).

I still don't know. You can only call the manual desk at 10000 and report the name of the original applicant (I reported it to my dad when I went to do it) and the installation address for them to check.
