The short answer
This charge is your monthly payment to Optimum for high-speed home internet, cable television, or cellular service.
Why is Optimum / Altice USA charging my card?
The descriptor OPTIMUM*ONLINE corresponds to Altice USA, which operates under the Optimum brand (and previously Suddenlink). This deduction pays for your high-speed internet, Optimum Mobile, or cable TV package.
Optimum is notorious for aggressive pricing step-ups after the first 12 months of service. If your charge suddenly spiked by $20 to $40, your promotional pricing has likely rolled off to the 'everyday rate.' It could also include a 'Network Enhancement Fee' or a charge for a missed service appointment.
