Hello.

I have problem with my RB912UAG-2HPnD + Huawei ME909u-521 device. I buy Orange LTE Internet card and i cant establish connection. Im try using LTE device and lte + ppp-out and it dsnt work. Sim pin is enabled, i cant disable it.

It work with all other sim cards (sic!). Ant this orange card is working on the PC. So its Huawei vs sim card fighting?

I get this error:

This problem occur at 6.35.2 (Current) and 6.36rc21 (Release candidate) RouterOS.

I downgrade to 5.26 (Legacy) and update to 6.32.3 via /system packages update in winbox and now everything works fine.
