This is a bit lengthy but it should produce your E5830, E5832 or E5838 unlock code for free!
Always REMOVE the SIM card before doing the read or you may get an corrupt file!
Download this version of QMAT.
Digital Kaos - Downloads - QMAT
Select the Application port of the E583x. Check in Windows Device Manager if unsure.
To test if you got the right port, send the "00" version command.
You should see something like this:
00 4A 61 6E 20 20 35 20 32 30 31 30 31 35 3A 31
38 3A 30 35 4A 75 6E 20 31 32 20 32 30 30 39 30
35 3A 30 30 3A 30 30 53 4E 43 41 41 4C 5A 4D 00
00 0D 00 00 00 01 B1
Then select: Read EFS and flag "Alternative Method".
Click "Let's go".
The resultant file contains both Binary and ASCII characters.
You will need to search for this for your 8 digit unlock code. There will be two codes in the file one is for removing the SIM lock and the other removes the Mi-Fi lock.
You can use Notepad to search the file, its crude but you should find the code in a few minutes. I have tried a program called ExtractText:
Windows 95+ programs
The results are hit and miss with this program, sometimes the code is on the last line sometimes it is at the top of the list! However, it might give you a good idea of what you're looking for! To cut down on unnecessary searching using Extract Text go to Options and then Text Options and set the parameters to: Minimum Character 7 and maximum characters 8 plus you should have only Numbers selected:
One thing to keep in mind, the unlock code will appear only once so you can ignore repeated codes. This should narrow the search down somewhat!
Do remember that you have 10 attempts to enter the correct code so do take a little time to chose the code!
A code entry to is included below....
If this seems complicated please ask someone else to do the task for you!
Please post your results!

This should provide some extra help:
Code viewed in Notepad:
Code viewed in Hex Editor:
It is worth noting that every modem I've come across so far, the correct 8 digit unlock code is preceded by Hex value 01 twice.

And also 8 digit unlock code is preceded by Hex value 01 twice.
Very thank again.
need unlock code for E5830S
anyhelp will be appreciated.
found it right at the top, but 01 01 hex values were there.
Also special character was there after the code.
Thanks for all the help
How can I get the code myself?
After reading the SIM unlock code from the device, how can one apply this code? Inserting a SIM from another operator should trigger the request for the unlock code? I'm trying to unlock a Huawei E5832S.
