MYLINE Carrier Selection Service

With this service, you won't need to dial an access code any more once you've registered your telephone company selection in each category. But you still will have the option of using other telephone companies. All you do is to dial their access code. And if you have a phone with special functions like ACR*, your phone will still select the telephone company automatically, even if you've registered a different telephone company. Please contact your telephone company if you have questions about ACR and other special functions.

*ACR (Automatic Carrier Routing): a function that automatically selects the telephone company (formerly called LCR or Least Cost Routing).

MYLINE PLUS Carrier Designation Service

MYLINE PLUS is for people who want to always use the same telephone company. MYLINE PLUS designates one telephone company as your regular registered service provider in each category. With MYLINE PLUS you always call through your designated telephone company, even if you happen to dial a different telephone company's access code.
