Hi,
I’ve EM7455 installed on DELL E7270 running Windows 10 Pro 64 bit. After install latest Sierra QMI drivers and looks running fine. I’ve inserted SIM and could access internet without any issues. I don’t understand about “Activatioln” because so far doesn’t requests for “Activation”. What do you means about Activation ? Could you elaborate more about which hardware ? HP, LENOVO, DELL or Clone PC.
