Wires from (most) SVB accounts are free so, that's factually inaccurate. If you had an account that didn't have free wires you had the wrong kind of account.
Not sure what kind of contract you have but outside of a discount on the first N wires, all the accounts have fees for wires, both domestic and international. Were you transferring directly to another SVB account?
Nope! But this is a regular SVB checking account not one through Atlas so I'm not sure what the differences are. My comment is defending SVB the bank, not necessarily the Atlas account which I have less knowledge of.
Wires were not free for me. I received a few wires from Sweden and recall paying a fee for each. Additionally there is an account service fee ($15) each month.
