How and how to connect a SIM card to a PC?

Question

Telephony

Hello. Dear, tell me, what are the least expensive ways to connect a regular SIM card to a PC on win7? It is necessary that the process of reconnecting / disconnecting itself is not stressful - so that the operator can come in the morning, connect his SIM card, and work with the software on the PC as with a cell phone (such as a sip client). At the same time, there is no Internet on the PC, and the usual sip client will not work. It is necessary to think of something with iron. From what I googled - just buy a 4g modem and flash it for voice communication. I wonder if the toaster public knows other options?

Answer 1

Multiphone service from a megaphone. Put a sip dialer on the PC, change the mode to sip, at the end of the day back to sim.
