1. Dual sim support, so that it shows which sms came thru which sim. 2. Should allow to reply with whichever sim we like. Both of the above are most basic and the android default message app itself has them. 3. Should have a word filter to reject emails or store them separately without pinging and disturbing me (multiple keywords based blocking will be super helpful). This the only thing im needing that's not in the default android sms app. This is all i want. The first 2 are already in the basic sms app that comes with android marshmallow. Its only that i want the third feature (keyword filter/blocking) without sacrificing the first 2 basic most features. For one year, tried installing more than 20 different types of sms apps. Of these 3 basics which i mentioned above it will be lacking one feature.Either they will have word blocking, but no dual sms identification (can't tell which sms came thru which sim). Or it can do dual sim recognition but it can't block keywords. .
