Payphone surcharges are charged by Payphone providers for calls to free phone numbers. A $0.99 surcharge will be billed to your account to connect a payphone call. Regular account per minute charges still apply.
NOTE: Payphone calls to local numbers do not incur a surcharge since the caller was required to pay for the call. The surcharge is subject to change.
