Fixed dialing
Use

feature lets you restrict your outgoing calls to phone numbers 
included in the fixed dialing list or beginning with the same 
digit(s) as an entry in the list. For example, a fixed dialing list 
that includes the numbers “18886654228” and “214” allows 
calls to 1-888-665-4228 and to any phone number beginning 
with 214.
Notes about fixed dialing
• Fixed dialing works only with SIM cards that support it.
• If you turn fixed dialing on and don’t have any numbers 
in the fixed dialing list, you can’t make any calls!
• When fixed dialing is on, calls may be possible to certain 
emergency numbers in some networks (e.g. 911 or other 
official emergency number).
• You can’t access the fixed dialing list like you access 
your phone book. Instead, press

Name:
 prompt, either enter part of

list, press the number key that corresponds to the first
