dual sims need different ring tones & text message notification sounds
I have two sims and I'm looking to be able to tell which one is ringing or which one has an incoming text. It's important because one has unlimited text and talk while the other gets only 20 minutes/texts per month, then I pay for each one. When I get a spam call or text, I can't tell which line it's on without a differentiating sound. I end up wasting money after my limited number of calls is used up by dealing with junk. How can I change the sounds for the different lines so I don't waste money?
