Hi everyone.
Just got a GL-X750 v2 and set it up right away with the old firmware, i guess it was 3.0. SIM worked immediately, but i noticed that multible wan is missing, so I did the upgrade via the bin-file from the official web site.
Now, I have 4.0, multiple wan, but the SIM can’t be unlocked. „SIM card has been locked, please input the PIN code to unlock it.“
OK then, tried the SIM in my old router and it works just fine. Tried it in a phone and it works just fine. Reset the GL.iNet and tried again. Same error.
What am I doing wrong here? Please help me out.
