I have tried over 7 different multi-sim phones, both smart and feature phone and this is by far the best on to date. It allows use of 3 sims (always on) with very easy switching between each one to make outgoing calls. Good build quality and battery life is great. I use it only as a phone, I have a separate smart phone and tablet for everything else, so I can't comment on its surfing and data qualities.Perfect for what i need. I wish LG would make a quad sim phone now.
