Ye, that’s crap, but seems mostly an Apple issue. If you need a PC with both, you buy a business class machine (which I do anyway, because consumer lines suck).

But that approach you lose wifi.

Though I have 3 laptops with both wifi and cell, 2 old Dells and a newer Lenovo.

I think the complaint here is Apple not even giving the option of both simultaneously.

1. Voice calls via POTS isn’t a big thing via laptop. Most calls like this are now via apps. Hell, I despise using POTS any more, my phone SIM doesn’t even do voice, all calls are VOIP now via a service that interconnects with POTS.

2. You can use a SIM dongle for laptops without a built-in modem. Though business class laptops have a cell modem as an option

There’s just little call for circuit-based voice calls any more. Those connections are more sensitive to network issues, and I’d bet most voice calls are some form of VOIP anyway. If you really need circuit-based calling, you can still do it over IP using a service like jmp.chat

I have 3.

It just has to be chosen as an option at purchase time. Though usually consumer lines don’t have the option.
