You can pay online or through the phone.Alsi you can pay in person at the. Harbour Tunnel, or Fort McHenry. Also at MVA
As far as I know, the only way to technically pay by phone would be to drive through the ez-pass lane and incur a toll violation which will increase the toll amount by 50%. Then wait for the bill to show up and go to the ezpass website on your phone to pay for it. If you want to prepay tolls, get an ezpass. It will make the tolls a bit cheaper too as an added benefit. You could also check their website or call the ezpass office to try to find out if there are other ways.
