Can I access cell tower data on the nrf9160 dk without a SIM card?

Hello,

I'm working on a project for my university course and have been tasked with developing an asset tracker that uses only LTE-M and NB-IoT technologies. Tracking data will be stored locally on an SD card that I will interface with the device. One of my project requirements is for the nrf9160 dk to operate without a SIM card. Is this possible? Am I able to use AT commands like NCELLMEAS to acquire data without a SIM card? We were thinking it may be possible since mobile phones without SIM cards can still see nearby towers and contact emergency services.

Regards,
