I'm trying to add a unique ringtone to text messages that come from a specific user. But for some reason, the default ringtone keeps overriding the one I chose. Any suggestions? I receive text messages from the USGS Earthquake Monitoring Center and I want my created "quake alert" mp3 to sound when messages come from them. I already created a contact called "Earthquake Alert" with the matching phone number that sends the text but the default ringtone still sounds when a message is received. What am I doing wrong.
