Silent ring ins
I just saved the number into my phonebook and set the ringer for silent.
If this phone does not have the 'silent' as a ringer option you might could make a ringer.
I just bought this phone from T mobile but I won't get it for two days (purchased online).
Will the phone let you create your own ringers? If so, just record a second or two of silence and set that for the ringer.
