Quectel EC25 Mini PCle 4G/LTE Module - SIM card required?

Hello,
We are looking to integrate this module into an android digital signage display. The display has a mPCIe 4g slot for this card, and an empty SIM slot. Is the idea that we need to get a SIM card for each of the displays to have 4G access? Or would this module allow for some type of connectivity without using a SIM? Also, do you see any reason the drivers wouldn’t work on a modern Android display?

Hello,

The SIM card is required for each module to get access of 4G network.

Regarding the Android driver, please contact the module OEM support.
