Let's say I have a regular SIM card that can make regular calls and send/receive SMS, and provides 4G and 5G connectivity while inserted in my Android phone. If the Nitowall were connected to the Internet via 4G and were to provide connectivity to an Android phone via WiFi, would it be possible to make regular phone calls and send/receive SMS through the phone number linked to the SIM card on the smartphone? If so, would it require heavy additionnal configuration? Thank you
