Uconsole questions about making the LTE modem work on a multi carrier SIM

Straight Talk just offered me a $10/month data only tablet plan in addition to my phone plan.
Their SIMs are able to use TMobile, Verizon and ATT towers.

I have read forum posts regarding getting certain carrier SIMs to work right, but is the process the same for a multi carrier SIM?

Trying to find out before I sign up for this data plan.

Thanks!
