Did you buy a new phone ??? Did you port your mobile # to another carrier ??? Which model/manufacturer of the phones in question ??? Which carrier are you using ??? Your post is confusing.
after 2 seconds phone specifications
tried everthing, but in the end (after a total of 20 hours skimming through numerous forums) i have this:
by mistake i had my old phone switched on while i was looking for more solutions and when i dialed to check, ringtone was working and voice
mail didn't cut in EUREKA!!!!!!!!!!!!!!!!!so i now have the old phone (Nokia100) permanently ON -ringtone on 0 volume- with the charger plugged in and both phones will ring for 30 secs (default) before going to voice mail
swapping SIMs -both for the same number- didn't help
talked to reps from both the store i bought the phone from and the carrier and reactions went from "no such thing" "never heard of this before" to "why didn't you buy an iPhone?"
if either phone is turned off then voicemail will activate after 2 seconds
