Unlock code for Huawei E3531s-2 O2 Germany

[slamhard]

Hello,

Thank you for the response.

I will try with : Unlock (V3): 10152924
The other two are not working.

Should i just insert it in the browser page that opens when i plug the dongle in the PC? It's a page from O2, on local host 192.168.0.1 and it requires the code for SIM unlock. Or should i use a tool for writing the code ?

Thank you!
