why does mobile data either get really bad or automatically disconnect when making a call. Then gets restored once the call ends.

If your phone is not compatible with calls over 4G (does not support your carrier’s configuration of VoLTE) or 5G (does not support VoNR) it will switch to 3G or 2G to make a call. Data may not be available or be very limited because not many frequencies are allocated for 3G and 2G these days.

Your call and the mobile data go over the same bandwidth. When you are making a voice call, a lot of bandwidth is needed for the call alone, leaving little for the data connection, which can indeed lead to interruptions in the data you are getting.

Does it?
I don’t agree with this as a statement of fact.

What’s more irritating to me is that my phone (s22) drops my mobile connection when I make a *data* call. So if I use my company’s voip (ringcentral), or even a mobile appointment with a doctor, I’ll lose 4g/5g, and thus the entire call. The issues resolve if I use a VPN. If I’m fast enough getting the VPN on after the call drops, I can pick them back up in 5 to 10 seconds.

Usually phones have some components that are shared for different connection bearers. Some phones can do both voice calls and internet traffic through 3-4-5G due to additional modulator-demodulator-antenna. Some don’t because they have only one mod-demod-antenna and the system prioritizes calls over internet traffic.
This doesn’t happen when you are connected via WiFi, there are other components handling the processes there.
