Im using a dual sim phone and its spot on. Can recieve calls on both sims and it gives you the option to choose which sim you want to choose each time you make a call. Great idea tbh.
Aye I've got it active now, I like it!
It actually works. I've had dual sim phone sin the past and they are garbage. This works very well. Very handy!
Guess dual sim has moved on since I last dabbled.
