Which edition of the S7 do you have. The ONLY one that it is possible to switch from Verizon to AT&T on is the Carrier Unbranded / Unlocked edition, the SM-G930U & SM-G935U.
The carrier branded Verizon has a Snapdragon 820 with only the CDMA radio
The carrier branded AT&T has a GSM radio
Only the Unlocked editions have both radios available, allowing for use of any GSM or any CDMA Sim card.
The G930A is not the same as the G930V in terms of the radios.
Hope this helps
