Panic! What does this system report mean?

Hi there! I was online and then Safari quit unexpectedly and here what I´ve got:

panic(cpu 1 caller 0x001A3135): Unresolved kernel trap (CPU 1, Type 14=page fault), registers:

Can please anyone tell me what does it mean? I keep on having this problem again and again and cannot work with Safari anymore and have to use Firefox instead

It seems to be a problem with your Huawei Data Card. I am not very familiar with these cards but I found a discussion on a different forum with people having the same issue, I just skimmed it but I believe they may have found a fix.

Good Luck
