Not detecting sim card T460s

My laptop is not detecting the sim card, it came with a sim that it also cannot detect. The message displayed is: Insert Sim. 

The sim is on O2 network and works in my ipad.  

 

I have rebooted and installed all latestr firmwares.

Re: Not detecting sim card T460s

Hello and welcome

I think you insert the SIM card while the laptop is powered on. This behavior causes issue you face with. So, to insert the SIM card power off the laptop completely, using the Shift key and remove the AC charger.

Also, make sure the SIM card doesn't need the PIN code.

Re: Not detecting sim card T460s

I hope you insert the SIM card carefully and properly, according to the laptop User Guide. Its tray is frangible enough.

Is the SIM card tariff/contract universal, for both, tablets and modems? There might be restrictions depending on cellular operator. Is O2 your home network? Do you have another SIM card with internet access service activated, at least for the test purpose?

Regarding the wwan card installed: is there em7455 entry in the Windows Device Manager, without errors?
