Verizon and AT&T are not compatible networks. Also the tablet would have to be unlocked for it to work in any case. It wouldn't work, sorry.
Verizon is CDMA. AT&T is GSM. Completely different networks. Not compatible.

I thought all Verizon devices were SIM unlocked? I'd think since their unlocked phones mostly work on GSM networks, the Tab S2 would as well. Straight CDMA isn't really a thing anymore...modern Verizon hardware uses a SIM for data, CDMA architecture for voice.
