[PLUG-TALK] Mobile phone SIM card question

Will a SIM card sold by one AT&T MVNO work with another AT&T MVNO?

My research did not provide an answer, but one site suggested that in
addition to the phone's number, password, carrier, and contacts the SIM also
specifies the calling plan. If so, would this require a new SIM card for a
new provider?
