set another CDMA operator in a verizon wireless galaxy tab Got a galaxy tab 7 SCHI800BKV verizon wireless tab. It has no rim/sim port. Question is if I root the device will it be possible to set my country's CDMA operator in the device?

Thanks for your help.
Generally speaking, rooting is completely unrelated to unlocking.

CDMA unlocking is also more difficult than SIM unlocking a GSM phone, and CDMA phones need to be activated on the network, unlike sticking a SIM in an unlocked GSM phone and doing whatever you want.  You'll need help from both carriers (Verizon to unlock, your carrier to activate) in order to do this.
