Mikrotik BaseBox 5 (v.6.33.5) + LTE Huawei ME909S-120

Hi fox,
I’m trying to set up the mini pcie LTE modem Huawei ME909s-120 on basebox 5.
I’ve just switched from usb modem e3392 where I had a connection.

With mini pcie, lte interface is identified, DHCP client is set up and IP received but no connection, no ping.
Any suggestions?
