ry emergency calls to any type of hospital, law en-
forcement agency, medical care unit ("Emergency
Service(s)") or any other kind of Emergency Ser-
vice. You must make additional arrangements to ac-

your responsibility to purchase traditional wireless
or landline telephone services to access Emergency
Services.
