Bar Calls and Texts to data SIM

Just purchased and received a HiPad X LTE. I put a data only SIM in one of the SIM slots. Immediately after setup I get 3 calls from an unknown number. Wonder how someone got hold of the number for the data sim.

Obviously I need to bar calling and texting for this data SIM. I turned on the Do Not Disturb feature for this purpose. Any other way to bar all calls, text messages and their notifications?
