After knowing that my Redmi doesn’t come with the feature that let me set different ringtones for each SIM, I actually tried out the DualSim Ringtone app.
So did it work on my Redmi ?
As far as I’ve tested, it didn’t work.
In DualSim Ringtone, I can set a different ringtone and message tone for each SIM (See images below). While the ringtone worked most of the time (Unfortunately, it didn’t work 100%), the message didn’t work at all.
According to the developer, in order for the message tone to work you need to set the message tone to “Default” in the Messaging app or Sound Settings. Unfortunately, you can’t do that in MIUI.
Have you tried DualSIM Ringtone or any other similar apps on your Redmi or Redmi Note ? Let me know your results in the comments.
